In my first two data posts for 2025, I looked at the strong year that US equities had in 2024, but a very good year for the overall market does not always translate into equivalent returns across segments of the market. In this post, I will remain focused on US equities, but I will break them into groupings, looking for differences. I first classify US stocks by sector, to see return variations across different industry groupings. I follow up by looking at companies broken down by market capitalization,  with an eye on whether the much-vaunted small cap premium has made a comeback. In the process, I also look how much the market owes its winnings to its biggest companies, with the Mag Seven coming under the microscope. In the next section, I  look at stock returns for companies in different price to book deciles, in a simplistic assessment of the value premium. With both the size and value premiums, I will extend my assessment over time to see how (and why) these premiums have changed, with lessons for analysts and investors. In the final section, I look at companies categorized by price momentum coming into 2024, to track whether winning stocks in 2023 were more likely to be winners or losers in 2024. US Stocks, by Sector (and Industry)        It is true that you very seldom see a market advance that is balanced across sectors and industries. This market (US stocks in 2024) spread its winnings across sectors disproportionately, with four sectors - technology, communication services, consumer discretionary and financials - delivering returns in excess of 20% in 2024, and three sectors - health care, materials and real estate delivering returns close to zero: Sector Returns - Historical (with $ changes in millions) The performance of technology stocks collectively becomes even more impressive, when you look at the fact that they added almost $4.63 trillion in market cap just in 2024, and that over the last five (ten) years, the sector has added $11.3 trillion ($13.6 trillion) in market cap.     I  break the sectors down into 93 industries, to get a finer layer of detail, and there again there are vast differences between winning and losing industry groups, based upon stock price performance in 2024: $ changes in millions While most of the industries on the worst-performing list represent old economy companies (steel, chemicals, rubber & tires), green energy finds itself on the list as well, perhaps because the "virtue trade" (where impact and socially conscious investors bought these companies for their greenness, rather than business models) lost its heft. The top two performers, in 2024, on the best performing industry list, semiconductors and auto & truck, owe much of their overall performance to super-performers in each one (Nvidia with semiconductors and Tesla with auto & truck), but airline companies also had a good year, though it may be premature to conclude that they have finally found working business models that can deliver profitability on a continuous basis. US Stocks, by Market Cap     For much of the last century, the conventional wisdom has been that small companies, with size measured by market cap, deliver higher returns than larger companies, on a risk-adjusted basis, with the debate being about whether that was because the risk measures were flawed or because small cap stocks were superior investments. That "small cap premium" has found its way into valuation practitioners playbooks, manifesting as an augmentation (of between 3-5%) on the cost of equity of small companies.  To get a sense of how market capitalization was related to returns, I classified all publicly traded US companies, by market cap, and looked at their returns in 2024. The returns across deciles are volatile, and while the lowest deciles in terms of market cap deliver higher percent returns, looking at the top and bottom halves of the market, in terms of market cap, you can see that there is not much setting apart the two groups.      To make an assessment of how the performance of small cap stocks in 2024 falls in the historical spectrum, I drew on Ken French's research return data, one of my favorite data sources, and looked at the small cap premium as the difference in compounded annual returns between the lowest and highest deciles of companies, in terms of market cap: My small cap premium spreadsheet, based on Ken French data In this graph, you can see the basis for the small cap premium, but only if go back all the way to 1927, and even with that extended time period, it is far stronger with equally weighted than with value weighted returns; the 1927-2024 small cap premium is 2.07% with value-weighted returns and 6.69% in  equally weighted terms. It should be noted that even its heyday, the small cap premium had some disconcerting features including the facts that almost of it was earned in one month (January) of each year, and that it was sensitive to starting and end points for annual data, with smaller premium in mid-year starting points. To see how dependent this premium is on the front end of the time period, I estimated the small cap premium with different starting years in the graph (and the table), and as you can see the small cap premium drops to zero with any time period that starts in 1970 and beyond. In fact, the small cap premium has become a large cap premium for much of this century, with small cap returns lagging large cap returns by about 4-4.5% in the last 20 years.     The market skew towards large cap companies can be seen even more dramatically, if you break stocks down by percentile, based upon market cap, and look at how much of the increase in market cap in US equities is accounted for by different percentile groupings: US Stocks: Market Cap Change Breakdown Looking across 6000 publicly traded stocks in 2024, the top percentile (about 60 stocks) accounted for 74% of the increase in market cap, and the top ten percent of all stocks delivered 94% of the change in total market capitalization.     Zeroing in even further and looking at the biggest companies in the top percentile, the Mag Seven, the concentration of winners at the very top is clear: $ changes in millions In 2024, seven companies (Apple, Amazon, Meta, Alphabet, Microsoft, Nvidia and Tesla) increased in market cap by $5.6 trillion, almost of the entire market's gain for the year. While it is not uncommon for stock market returns to be delivered by a few winners at the top,  with the Mag Seven, the domination extends over a decade, and in the last ten years (2014-2024), these seven companies have added $15.8 trillion in market cap, about 40% of the increase in market capitalization across all US stocks over the decade.     For years now, some investors have bet on a reversal in this trend line, with small cap stocks coming back in favor, and these investors have lagged the market badly. To get a better handle on why large cap stocks have acquired a dominant role, in markets, I look at three explanations that I have seen offered for the phenomenon: Momentum story: Momentum has always been a strong force in markets, in both directions, with price increases in stocks (decreases) followed by more price increases (decreases). In effect, winning stocks continue to win, drawing in new funds and investors, but when these same stocks start losing, the same process plays out in reverse. A reasonable argument can be made that increasing access to information and easing trading, for both individual and institutional investing, with a boost from social media, has increased momentum, and thus the stock prices of large cap stocks. The dark side of this story, though, is that if the momentum ever shifted, these large cap stocks could lose trillions in value. Passive investing: Over the last two decades, passive investing (in the form of index funds and ETFs) has taken market share from active investors, accounting for close to  50% of all invested funds in 2024. That shift has been driven by active investing underperformance and a surge in passive investing vehicles that are accessible to all investors. Since many passive investing vehicles hold all of the stocks in the index in proportion to their market cap, there presence and growth creates fund flows into large cap stocks and keeps their prices elevated. Here again, the dark side is that if fund flows reverse and became negative, i.e., investors start pulling money out of markets, large cap stocks will be disproportionately hurt. Industry economics: In writing about the disruption unleashed by tech start-ups, especially in the last two decades, I have noted the these disruptors have changed industry economics in many established businesses, replacing splintered, dispersed competition with consolidation. Thus, Meta and Alphabet now have dominant market shares of the advertising business, just as Uber, Lyft and Grab have consolidated the car service business. As industries consolidate, we are likely to see them dominated by a few, big winners, which will play out in the stock market as well. It is possible that antitrust laws and regulatory authorities will try to put constraints on these biggest winners, but as I noted in my post on the topic, it will not be easy. In my view, the small cap premium is not coming back, and given that it has been invisible for five decades now, the only explanation for why appraisers and analysts hold on to it is inertia. That said, the large cap premium that we have seen in the last two decades, was businesses have transitioned from splintered to consolidated structure, will also fade. Where does that leave us? Picking a company to invest in, based upon its market capitalization, will be, at best, a neutral strategy, and that should surprise no one. The Value Premium?     Just as the small cap premium acquired standing as conventional wisdom in the twentieth century, the data and research also indicated that stocks that trade at low price to book ratios earned higher returns that stocks that trade at high price to book ratios, in what was labeled as the value premium. As with the size premium, low price to book (value) stocks have struggled to deliver in the twenty first century, and as with the small size premium, investors have waited for it to return. To see how stocks in different price to book classes performed in 2024, I looked at returns in 2024, for all US stocks, broken down into price to book deciles: Deciles created based on price to book ratios at start of 2024 In 2024, at least, it was the companies in the top decile (highest price to book ratios) that delivered the best returns in 2024, and stocks in the lowest decile lagged the market.      Here again, Ken French's data is indispensable in gaining historical perspective, as I looked the difference in annual returns between the top decile and bottom decile of stocks, classified by price to book, going back to 1927: My value premium spreadsheet, based on Ken French data In this graph, I am computing the premium earned by low price to book stocks, in the US, with different starting points. Thus, if you go back to 1927 and look at returns on the lowest and highest deciles, the lowest decile earned an annual premium of 2.43%. That premium remains positive until you get to about 1990, when it switches signs; the lowest price to book stocks have earned 0.87% less annually between 1990 and 2024, than the highest price to book stocks. As was the case with the small cap premium, the premium earned by low price to book stocks over high price to book stocks has faded over time, spending more time in negative territory in the last 20 years, than positive.      Value investors, or at least the ones that use the conventional proxies for cheapness (low price to book or low PE ratios), have felt the effects, significantly under performing the market for much of the last two decades. While some of them still hold on to the hope that this is just a phase that will reverse, there are three fundamentals at play that may indicate that the low price to book premium will not be back, at least on a sustained basis: Price to book ≠ Value: It is true that using low price to book as an indicator of value is simplistic, and that there are multiple other factors (good management, earnings quality, moats) to consider before making a value judgment. It is also true that as the market's center of gravity has shifted towards companies with intangible assets, the troubles that accountants have had in putting a number on intangible asset investments has made book value less and less meaningful at companies, making it a poorer and poorer indicator of what a company's assets are worth. Momentum: In markets, the returns to value investing has generally moved inversely with the strength of momentum. Thus, the same forces that have strengthened the power of momentum, that we noted in the context of the fading of the small cap premium, have diluted the power  of value investing. Structural Shifts: At the heart of the premium earned by low price to book ratios is mean reversion, with much of the high returns earned by these stocks coming from moving towards the average (price to book) over time. While that worked in the twentieth century, when the US was the most mean-reverting and predictable market/economy of all time, it has lost its power as disruption and globalization have weakened mean reversion. So, what does this mean for the future? I see no payoff in investing in low price to book stocks and waiting for the value premium to return. As with market cap, I believe that the value effect will become volatile, with low price to book stocks winning in some years and high price to book stocks in others, and investing in one or another of these groups, just on the basis of their price to book ratios, will no longer deliver excess returns.     Since the fading of the small cap and value premiums can be traced at least partially to the strengthening of momentum, as a market force, I looked at the interplay between momentum and stock returns, by breaking companies into deciles, based upon stock price performance in the previous year (2023), and looking at returns in 2024: Deciles formed on percentage returns in 2023 As you can see, barring the bottom decile, which includes the biggest losers of 2023, where there was a strong bounce back (albeit less in dollar terms, than in percent), there was a strong momentum effect in 2024, with the biggest winners from last year (2023) continuing to win in 2024. In short, momentum continued its dominance in 2024, good news for traders who make money in its tailwinds, with the caveat that momentum is a fickle force, and that 2025 may be the year where it reverses. Implications     The US equity market in 2024 followed a pathway that has become familiar to investor in the last decade, with large companies, many with a tech focus, carried the market, and traditional strategies that delivered higher returns, such as investing in small cap or low price to book stocks, faltered. This is not a passing phase, and reflects the market coming to terms with a changed economic order and investor behavior. There are lessons from the year for almost everyone in the process, from investors to traders to corporate executive and regulators: For investors: I have said some harsh things about active investing, as practiced today, since much of it is based upon history and mean reversion. A mutual fund manager who screens stocks for low PE ratios and high growth, while demanding a hefty management fee, deserves to be replaced by an ETF or index fund, and that displacement will continue, pruning the active management population. For active investors who hold on to the hope that quant strategies or AI will let them rediscover their mojo, I am afraid that disappointment is awaiting them. For traders: Traders live and die on momentum, and as market momentum continues to get stronger, making money will look easy, until momentum shifts. Coming off a year like 2024, where chasing momentum would have delivered market-beating returns, the market may be setting up traders for a takedown. It may be time for traders to revisit and refine their skills at detecting market momentum shifts. For companies: Companies that measure their success through stock market returns may find that the market price has become a noisier judge of their actions. Thus, a company that takes a value destructive path that feeds into momentum may find the market rewarding it with a higher price, but it is playing a dangerous game that could turn against it.  For regulators: With momentum comes volatility and corrections, as momentum shifts, and those corrections will cause many to lose money, and for some, perhaps even their life savings. Regulators will feel the pressure to step in and protect these investors from their own mistakes, but in my view, it will be futile. In the markets that we inhabit, literally any investment can be an instrument for speculation. After all, Gamestop and AMC were fairly stolid stocks until they attracted the meme crowd, and Microstrategy, once a technology firm, has become almost entirely a Bitcoin play.  I recently watched Timothy Chalamet play Bob Dylan in the movie, A Complete Unknown,  and I was reminded of one of my favorite Dylan tunes, "The times they are a-changin".  I started my investing in the 1980s, in a very different market and time, and while I have not changed my investing principles, I have had to modify and adapt them to reflect a changed market environment. You may not agree with my view that both the small cap and value premiums are in our past, but it behooves you to question their existence.  YouTube Video Data Updates for 2025 Data Update 1 for 2025: The Draw (and Danger) of Data!

In my last post, I noted that the US has extended its dominance of global equities in recent years, increasing its share of market capitalization from 42% in at the start of 2023 to 44% at the start of 2024 to 49% at the start of 2025. That rise was driven by a surge in US equity values during 2024, with the S&P 500 delivering returns of close to 25%, all the more impressive, given that the index delivered returns in excess of 26% in 2023. In this post, I will zero in on US equities, in the aggregate, first by looking at month-by-month returns during 2024, and then putting their performance in the last two years in a historical context. I will follow up by trying to judge where markets stand at the start of 2025, starting with PE ratios, moving on to earnings yields and ending with a valuation of the index. US Equities in 2024     Entering 2024, there was trepidation about where stocks would go during the year especially coming off a a strong bounce back year in 2023, and there remained real concerns about inflation and a recession. The hopeful note was that the Fed would lower the Fed Funds rate during the course of the year, triggering (at least in the minds of Fed watchers) lower interest rates across the yield curve, Clearly, the market not only fought through those concerns, but did so in the face of rising treasury rates, especially at the long end of the spectrum.      While the market was up strongly for the year, it is worth remembering that the there were months during 2024, where the market looked shaky, as can be seen in the month to month returns on the S&P 500 during the course of 2025: The market’s weakest month was April 2025, and it ended the year or a weak note, down 2.50% in December. Overall, though the index was up 23.31% for the year, and adding the dividend yield of 1.57% (based upon the expected dividends for 2025 and the index at the start of the years) yields a total return 24.88% for the year: As is almost always the case, the bulk of the returns from equity came from price appreciation, with the caveat that the dividend yield portion has shrunk over the last few decades in the United States. Historical Context     To assess stock returns in 2024, it makes sense to step back and put the year's performance into historical perspective. In the graph below, I look at returns (inclusive of dividends) on the S&P 500 every year from 1928 to 2024.  Download historical data Across the 97 years that I have estimated annual returns, stocks have had their ups and downs, delivering positive returns in 71 years and negative returns in the other 26 years. The worst year in history was 1931, with stocks returning -43.84%, and the best year was 1954, when the annual return was 52.56%. If you wanted to pick a benchmark to compare annual returns to pass judgment on whether a year was above or below average, you can can go with either the annual return (11.79%) or the median return (14.82%) across the entire time period.     Looking at the 24.88% return in 2024 in terms of rankings, it ranks as the 27th best year across the last 97 years, indicating that while it was a good year, there have been far better years for US stocks. Combining 2023 and 2024 returns yield a cumulative a two-year return for the S&P 500 of 57.42%, making it one the ten best two-year periods in US market history.      The riskless alternative to investing in US stocks during this period, in US dollar terms, are US treasuries, and in 2024, that contest was won, hands down, by US equities: Equity risk premium earned in 2024, over 3-month  treasury bills  = Return on stocks - Return on 3-month treasuries (averaged over 2024)  = 24.88% -4.97% = 19.91% Equity risk premium earned in 2024, over 10-year treasuries = Return on stocks - Return on 10-year treasury = 24.88% -(-1.64%) = 26.52% The ten-year treasury return was negative, because treasury bond rates rose during 2024.      Equity risk premiums are volatile over time, and averaging them makes sense, and in the table below, I look at the premium that stocks have earned over treasury bills and treasury bonds, going back to 1928, using both simple averages (of the returns each year) and geometric averages (reflecting the compounding effect): Download historical data These returns are nominal returns, and inflation would have taken a bite out of returns each year. Computing the returns in real terms, by taking out inflation in each year from that year's returns, and recomputing the equity risk premiums: Download historical data Note that the equity risk premiums move only slightly, because inflation finds its way into both stock and treasury returns.     Many valuation practitioners use these historical averages, when forecasting equity risk premiums in the future, but it is a practice that deserves scrutiny, partly because it is backward looking (with the expectation that things will revert back to the way they used to be), but mostly because the estimates that you get for the equity risk premium have significant error terms (see standard errors listed below the estimates in the table). Thus, if are using the average equity risk premium for the last 97 years of 5.44% (7.00%), i.e., the arithmetic or geometric averages, it behooves you to also inform users that the standard error of 2.12% will create a range of about 4% on either side of the estimate. Pricing Questions     Coming into 2025, investors are right to be trepidatious, for many reasons, but mostly because we are coming off two extraordinarily good years for the market, and a correction seems due. That is, however, a poor basis for market timing, because stock market history is full of examples to the contrary. There are other metrics, though, which are signaling danger, and in this section, I will wrestle with what they tell us about stocks in 2025. PE ratios and Earnings Yields     Even as we get new and updated pricing metrics, it is undeniable that the most widely used metric of stock market cheapness or expensiveness is the price earnings ratio, albeit with variations in the earning number that goes into the denominator on timing (current, last 12 months or trailing or next 12 month of forward), share count (diluted, primary) and measurement (ordinary or extraordinary). In the graph below, I focus on trailing earnings for all companies in the S&P 500 and compute the aggregated PE ratio for the index to be 24.16 at the start of 2025, higher than the average value for that ratio in every decade going back to 1970.  Download data Just for completeness, I compute two other variants of the PE, the first using average earnings over the previous ten years (normalized) and the second using the average earnings over the last ten years, adjusted for inflation (CAPE or Shiller PE). At the start of 2025, the normalized PE and CAPE also come in at well above historical norms.     If I have terrified you with the PE story, and you have undoubtedly heard variants of this story from market experts and strategists for much of the last decade, I would hasten to add that investing on that basis would have kept you out of stocks for much of the last ten years, with catastrophic consequences for your portfolio. For some of this period, at least, you could justify the higher PE ratios with much lower treasury rates than historic norms,, and one way to see this is to compare the earnings yield, i.e., the inverse of the PE ratio, with the treasury yields, which is what I have done in the graph below: Download data If you compare the earnings yield to the ten-year treasury rate, you can see that for much of the last decade, going into 2022, the earnings yield, while low, was in excess of the ten-year rate. As rates have risen, though, the difference has narrowed, and at the start of 2025, the earnings yield exceeded the treasury rate. If you see market strategists or journalists talking about negative equity risk premiums, this (the difference between the earnings yield and the treasury rate) is the number that they are referencing.     At this stage, you may be ready to bail on stocks, but I have one final card to play. In a post in 2023, I talked about equity risk premiums, and the implicit assumptions that you make when you use the earning to price ratio as your measure of the expected return on stocks. It works only if you make one of two assumptions: That there will be no growth in earnings in the future, i.e., you will earn last year's earnings every year in perpetuity, making stocks into glorified bonds.  In a more subtle variants, there will be growth, but that growth will come from investments that earn returns equal to the cost of equity. The problem with both assumptions is that they are in conflict with the data. First, the earnings on the S&P 500 companies has increased 6.58% a year between 2000 and 2024, making the no-growth assumption a non-started. Second, the return on equity for the S&P 500 companies was 20.61% in 2023, and has averaged 16.38% since 2000, both numbers well in excess of the cost of equity.     So, what is the alternative? Starting 30 years ago, I began estimating a more complete expected return on stocks, using the S&P 500, with the level of the index standing in for the price you pay for stocks, and expected earnings and cash flows, based upon consensus estimates of earnings and cash payout ratios. I solve for an internal rate of return for stocks, based upon these expected cash flows: The expected return from this approach will be different from the earnings to price ratio because it incorporate expected growth and changes in cash flow patterns. The critique that this approach requires assumptions about the future (growth and cash flows) is disingenuous, since the earnings yield approach makes assumptions about both as well (no growth or no excess returns), and I will wager that the full ERP approach is on more defensible ground than the earning yield approach.      Using this approach at the start of 2025 to the S&P 500, I back out an implied expect return of 8.91% for the index, and an implied equity risk premium of 4.33% (obtained by netting out the ten-year bond rate on Jan 1, 2025, of 4.58%): Implied ERP calculation in 2025 You are welcome to take issue with the number that I use there, lowering the growth rates for the future or changing the assumptions about payout. That is a healthy debate, and one that provides far more room for nuance that looking at the earnings yield.         How does an implied equity risk premium play out in market level arguments? Every argument about markets (from them being in a bubble to basement level bargains) can be restated in terms of the equity risk premium. If you believe that the equity risk premium today (4.33%) is too low, you are, in effect, stating that stocks are overvalued, and if you view it as too high, you are taking the opposite position. If you are not in the market timing business, you take the current premium as a fair premium, and move on. To provide perspective on the ERP at the start of 2025, take a look at this graph, that lists implied ERP at the start of each year going back to 1960: Historical implied ERP There is something here for almost point of view. If you are sanguine about stock market levels, you could point to the current premium (4.33%) being close to the historical average across the entire time period (4.25%). If you believe that stocks are over priced, you may base that on the current premium being lower than the average since 2005. I will not hide behind the "one hand, other hand" dance that so many strategists do. I think that we face significant volatility (inflation, tariffs, war) in the year to come, and I would be more comfortable with a higher ERP. At the same time, I don't fall into the bubble crowd, since the ERP is not 2%, as it was at the end of 1999.  Valuation Questions     Pulling together the disparate strands that are part of this post, I valued the index at the start of 2025, using the earnings expectations from analysts as the forecasted earnings for 2025 and 2026, before lowering growth rates to match the risk free rate in 2029. As the growth rates changes, I also adjust the payout ratios, given the return on equity for the S&P 500 companies: Download spreadsheet With the assumption that the equity risk premium will climb back to 4.5%, higher than the average for the 1960-2024 period, but lower than the post-2008 average, the value that I get for the index is about 5260, about 12% lower than the index at the start of the year. Note that this is a value for the index today, and if you wanted to adopt the market strategist approach of forecasting where the index will be a year from now, you would have to grow the value at the price appreciation portion (about 7.5%) of the expected return (which is 9.08%).     As I see it, there are two major dangers that lurk, with the first being higher inflation (translating into higher treasury rates) and the second being a market crisis that will push up the equity risk premium, since with those pieces in play, the index becomes much more significantly over valued. From an earnings perspective, the risk is that future earnings will come in well below expectations, either because the economy slows or because of trade frictions. Rather than wring my hands about these uncertainties, I fell back on a tool that I use when confronted with change, which is a simulation: Crystal Ball used for simulations While the base case conclusion that the market is overvalued stays intact, not surprising since my distributions for the input variables were centered on my base assumptions, there is a far richer set of output. Put simply, at today's price levels, there is an 80% chance that stocks are overvalued and only a 20% chance that they are undervalued. That said, though, if you are bullish, I can see a pathway to getting to a higher value, with higher earnings, lower interest rates and a continued decline in the equity risk premium. Conversely, you are bearish, I understand your point of view, especially if you see earnings shocks (from a recession or a tariff war), rising inflation or a market crisis coming up.     I don't dish out market advice, and as one whose market timing skills are questionable, you should not take my (or anyone else's) assessments at face value, especially heading into a year, where change will be the byword. It is possible that lower taxes and less regulation may cause to come in higher than expected, and that global investment fund flows will keep interest rates and equity risk premiums low. My advice is that you download the valuation spreadsheet, change the inputs to reflect your views of the world, and value the index yourself. Good investing requires taking ownership of the decisions and judgments you make, and I am glad to provide tools that help you in that process.

For the last four decades, I have spent the first week of each year collecting and analyzing data on publicly traded companies and sharing what I find with anyone who is interested. It is the end of the first full week in 2025, and my data update for the year is now up and running, and I plan to use this post to describe my data sample, my processes for computing industry statistics and the links to finding them. I will also repeat the caveats about how and where the data is best used, that I have always added to my updates. The Draw (and Dangers) of Data    It is the age of data, as both companies and investors claim to have tamed it to serve their commercial  interests. While I believe that data can lead to better decisions, I am wary about the claims made about what it can and cannot do in terms of optimizing decision making. I find its greatest use is on two dimensions: Fact-checking assertions: It has always been true that human beings assert beliefs as facts, but with social media at play, they can now make these assertion to much bigger audiences. In corporate finance and investing, which are areas that I work in, I find myself doing double takes as I listen to politicians, market experts and economists making statements about company and market behavior that are fairy tales, and data is often my weapon for discerning the truth.  Noise in predictions: One reason that the expert class is increasingly mistrusted is because of the unwillingness on the part of many in this class to admit to uncertainty in their forecasts for the future. Hiding behind their academic or professional credentials, they ask people to trust them to be right, but that trust has eroded. If these predictions are based upon data, as they claim they are, it is almost always the case that they come with error (noise) and that admitting to this is not a sign of weakness. In some cases, it is true that the size of that errors may be so large that those listening to the predictions may not act on them, but that is a healthy response. As I listen to many fall under the spell of data, with AI and analytics add to its allure, I am uncomfortable with the notion that data has all of the answers, and there two reasons why: Data can be biased: There is a widely held belief that data is objective, at least if it takes numerical form. In the hands of analysts who are biased or have agendas, data can be molded to fit pre-conceptions. I would like to claim to have no bias, but that would be a lie, since biases are often engrained and unconscious, but I have tried, as best as I can, to be transparent about the sample that I use, the data that I work with and how I compute my statistics. In some cases, that may frustrate you, if you are looking for precision, since I offer a range of values, based upon different sampling and estimation choices.  Taking a look at my tax rate calculations, by industry, for US companies, int the start of 2025, I report the following tax rates across companies. Effective tax rates, by Industry (US) Note, that the tax rates for US companies range from 6.75% to 26.43%, depending on how I compute the rate, and which companies I use to arrive at that estimate. If you start with the pre-conception that US companies do not pay their fair share in taxes, you will latch on to the 6.75% as your estimated tax rate, whereas if you are in the camp that believes that US companies pay their fair share (or more), you may find 26.43% to be your preferred estimate.  Past versus Future: Investors and companies often base their future predictions on the past, and while that is entirely understandable, there is a reason why every investment pitch comes with the disclaimer that “past performance is not a reliable indicator of future performance”. I have written about how mean reversion is at the heart of many active investing strategies, and why assuming that history will repeat can be a mistake. Thus, as you peruse my historical data on implied equity risk premiums or PE ratios for the S&P 500 over time, you may be tempted to compute averages and use them in your investment strategies, or use my industry averages for debt ratios and pricing multiples as the target for every company in the peer group, but you should hold back.  The Sample     It is undeniable that data is more accessible and available than ever before, and I am a beneficiary. I draw my data from many raw data sources, some of which are freely available to everyone, some of which I pay for and some of which I have access to, because I work at a business school in a university. For company data, my primary source is S&P Capital IQ, augmented with data from a Bloomberg terminal. For the segment of my data that is macroeconomic, my primary source is FRED, the data set maintained by the Federal Reserve Bank, but I supplement with other data that I found online, including NAIC for bond spread data and Political Risk Services (PRS) for country risk scores.      My dataset includes all publicly traded companies listed at the start of the year, with a market price available, and there were 47810 firms in my sample, roughly in line with the sample sizes in the last few years. Not surprisingly, the company listings are across the world, and I look at the breakdown of companies, by number and market cap, by geography: As you can see, the market cap of US companies at the start of 2025 accounted for roughly 49% of the market cap of global stocks, up from 44% at the start of 2024 and 42% at the start of 2023. In the table below, we compare the changes in regional market capitalizations (in $ millions) over time. Breaking down companies by (S&P) sector,  again both in numbers and market cap, here is what I get: While industrials the most listed stocks, technology accounts for 21% of the market cap of all listed stocks, globally, making it the most valuable sector. Thee are wide differences across regions, though, in sector breakdown: Much of the increase in market capitalization for US equities has come from a surging technology sector, and it is striking that Europe has the lowest percent of value from tech companies of any of the broad subgroups in this table.     I also create a more detailed breakdown of companies into 94 industry groups, loosely structured to stay with industry groupings that I originally created in the 1990s from Value Line data, to allow for comparisons across time. I know that this classification is at odds with the industry classifications based upon SIC or NAICS codes, but it works well enough for me, at least in the context of corporate finance and valuation. For some of you, my industry classifications may be overly broad, but if you want to use a more focused peer group, I am afraid that you will have to look elsewhere. The industry averages that I report are also provided using the regional breakdown above. If you want to check out which industry group a company falls into, please click on this file (a very large one that may take a while to download) for that detail. The Variables     The variables that I report industry-average statistics for reflect my interests, and they range the spectrum, with risk, profitability, leverage, and dividend metrics thrown into the mix. Since I teach corporate finance and valuation, I find it useful to break down the data that I report based upon these groupings. The corporate finance grouping includes variables that help in the decisions that businesses need to make on investing, financing and dividends (with links to the US data for 2025, but you can find more extensive data links here.) table.tableizer-table { font-size: 12px; border: 1px solid #CCC; font-family: Arial, Helvetica, sans-serif; } .tableizer-table td { padding: 4px; margin: 3px; border: 1px solid #CCC; } .tableizer-table th { background-color: #104E8B; color: #FFF; font-weight: bold; }  Corporate Governance & Descriptive      1. Insider, CEO & Institutional holdings      2. Aggregate operating numbers      3. Employee Count & Compensation           Investing Principle Financing Principle Dividend Principle  Hurdle RateProject ReturnsFinancing MixFinancing TypeCash ReturnDividends/Buybacks 1. Beta & Risk1. Return on Equity1. Debt Ratios & Fundamentals1. Debt Details1. Dividends and Potential Dividends (FCFE)1.Buybacks 2. Equity Risk Premiums2. Return on (invested) capital2. Ratings & Spreads2. Lease Effect2. Dividend yield & payout  3. Default Spreads3. Margins & ROC3.

In addition, within each of the datasets (in excel format), you will find a page defining the variables used in that dataset.  The Timing     These datasets were all compiled in the last four days and reflect data available at the start of 2025. For market numbers, like market capitalization, interest rates and risk premiums, these numbers are current, reflecting the market's judgments at the start of 2025. For company financial numbers, I am reliant on accounting information, which gets updated on a quarterly basis. As a consequence, the accounting numbers reflect the most recent financial filings (usually September 30, 2024), and I use the trailing 12-month numbers through the most recent filing for flow numbers (income statement and cash flow statements) and the most recent balance sheet for stock numbers (balance sheet values).      While this practice may seem inconsistent, it reflects what investors in the market have available to them, to price stocks. After all, no investor has access to calendar year 2024 accounting numbers at the start of 2025, and it seems entirely consistent to me that the trailing PE ratio at the start of 2025 be computed using the price at the start of 2025 divided by the trailing income in the twelve months ending in September 2024. In the same vein, the expected growth rates for the future and earnings in forward years are obtained by looking at the most updated forecasts from analysts at the start of 2025.      Since I update the data only once a year, it will age as we go through 2025, but that aging will be most felt, if you use my pricing multiples (PE, PBV, EV to EBITDA etc.) and not so much with the accounting ratios (accounting returns). To the extent that interest rates and risk premiums will change over the course of the year, the data sets that use them (cost of capital, excess returns) allow for updating these macro numbers. In short, if the ten-year treasury rate climbs to 5% and equity risk premiums surge, you can update those numbers in the cost of capital worksheet, and get updated values. The Estimation Process     While I compute the data variables by company, I am restricted from sharing company-specific data by my raw data providers, and most of the data I report is at the industry level. That said, I have wrestled with how best to estimate and report industry statistics, since almost every statistical measure comes with caveats. For a metric like price earnings ratios, computing an average across companies will result in sampling bias (from eliminating money-losing firms) and be skewed by outliers in one direction (mostly positive, since PE ratios cannot be negative). Since this problem occurs across almost all the variables, I use an aggregated variant, where with PE, for instance, I aggregate the market capitalization of all the companies (including money losing firms) in an industry grouping and divide by the aggregated net income of all the companies, including money losers.      Since I include all publicly traded firms in my sample, with disclosure requirements varying across firms, there are variables where the data is missing or not disclosed. Rather than throw out these firms from the sample entirely, I keep them in my universe, but report values for only the firms with non-missing data. One example is my data on employees, a dataset that I added two years ago, where I report statistics like revenue per employee and compensation statistics. Since this is not a data item that is disclosed voluntarily only by some firms, the statistics are less reliable than on where there is universal disclosure.      On an upbeat note,  and speaking from the perspective of someone who has been doing this for a few decades, accounting standards around the world are less divergent now than in the past, and the data, even in small emerging markets, has far fewer missing items than ten or twenty years ago.  Accessing and Using the Data     The data that you will find on my website is for public consumption, and I have tried to organize it to make it easily accessible on my webpage. Note that the current year’s data can be accessed here: https://pages.stern.nyu.edu/~adamodar//New_Home_Page/datacurrent.html If you click on a link and it does not work, please try a different browser, since Google Chrome, in particular, has had issues with downloads on my server.     If you are interested in getting the data from previous years, it should be available in the archived data section on my webpage: https://pages.stern.nyu.edu/~adamodar//New_Home_Page/dataarchived.html This data goes back more than twenty years, for some data items and for US data, but only a decade or so for global markets.        Finally, the data is intended primarily for practitioners in corporate finance and valuation, and I hope that I can save you some time and help in valuations in real time. It is worth emphasizing that every data item on my page comes from public sources, and that anyone with time and access to data can recreate it.  For a complete reading of data usage, try this link: https://pages.stern.nyu.edu/~adamodar//New_Home_Page/datahistory.html If you are in a regulatory or legal dispute, and you are using my data to make your case, you are welcome to do so, but please do not drag me into the fight.  As for acknowledgements when using the data, I will repeat that I said in prior years. If you use my data and want to acknowledge that usage, I thank you, but if you skip that acknowledgement, I will not view it as a slight, and I certainly am not going to threaten you with legal consequences.     As a final note, please recognize that this I don't have a team working for me, and while that gives me the benefit of controlling the process, unlike the pope, I am extremely fallible. If you find mistakes or missing links, please let me know and I will fix them as quickly as I can. Finally, I have no desire to become a data service, and I cannot meet requests for customized data, no matter how reasonable they may be. I am sorry!

I am a teacher at heart, and every year, for more than two decades, I have invited people to join me in the classes that I teach at the Stern School of Business at New York University. Since I teach these classes only in the spring, and the first sessions for each of the classes will be in late January, I think this is a good time to provide some details on the classes, including content and structure. If you have read these missives in prior years, much of what I say will sound familiar, but I have added new content and updated the links you will need to partake in the classes.  My Motives for Teaching     I was in the second year of my MBA program at UCLA, when I had my moment on grace. I had taken a job as a teaching assistant, almost entirely because I needed the money to pay my tuition and living expenses, and in a subject (accounting) that did not excite me in the least. A few minutes after I walked in to teach my first class, I realized that I had found what I wanted to do for the rest of my life, and I have been a teacher ever since. Since that was 1983, this will be my forty first year teaching, and I have never once regretted my choice.     I know that teaching is not a profession held in high esteem anymore, for good and bad reasons, and I will not try to defend it here. It is possible that some of the critics are right, and I teach because I cannot do, but I like to think that there is more to my career choice than ineptitude. My motivations for teaching are manifold, and let me list some of them: I like the stage: I believe that every teacher, to some extent, has a little bit of a repressed actor in him or her, and I do enjoy being in front of an audience, with the added benefit that I get to review the audience, with the grades that I given them, rather than the other way around. I like to make a difference: I do not expect my students to agree with all or even much of what I have to say, but I would like to think that I sometimes change the way they think about finance, and perhaps even affect their choice of professions. I am lucky enough to hear from students who were in my classes decades ago, and to find out that my teaching made a difference in their lives.  I like not having a boss: I would be a terrible employee, since I am headstrong, opinionated and awfully lazy, especially when I must do things I don’t like to do. As a teacher, I am my own boss and find my foibles completely understandable and forgivable. I know that teaching may not be your cup of tea, but I do hope that you enjoy whatever you do, as much as I do teaching, and I would like to think that some of that joy comes through. My Teaching Process     I do a session on how to teach for business school faculty, and I emphasize that there is no one template for a good teacher. I am an old-fashioned lecturer, a control freak when it comes to what happens in my classroom. In forty years of teaching, I have never once had a guest lecturer in my classroom or turned my class over to a free-for-all discussion. Class narrative: This may be a quirk of mine, but I stay away from teaching classes that are collections of topics. In my view, having a unifying narrative not only makes a class more fun to teach, but also more memorable. As you look at my class list in the next section, you will note that each of the classes is built around a story line, with the sessions building up to what is hopefully a climax. Bulking up the reasoning muscle: When asked a question in class, even if I know the answer, I try to not only reason my way to an answer, but to also be open about doubts that I may have about that answer. In keeping with the old saying that it is better to teach someone to fish, than to give them fish, I believe it is my job to equip my students with the capacity to come up with answers to questions that they may face in the future. In my post on the threat that AI poses to us, I argued that one advantage we have over AI is the capacity to reason, but that the ease of looking up answers online, i.e., the Google search curse, is eating away at that capacity. Make it real: I know that, and especially so in business schools, students feel that what they are learning will not work in the real world. I like to think that my classes are firmly grounded in reality, with my examples being real companies in real time. I am aware of the risks that when you work with companies in real time, your mistakes will also play out in real time, but I am okay with being wrong.  Straight answers: When I was a student, I remember being frustrated by teachers, who so thoroughly hedged themselves, with the one hand and the other hand playing out, that they left me unclear about what they were saying. I would like to think that I do not hold back, and that I stay true to the motto that I would rather be transparently wrong than opaquely right. It has sometimes got me some blowback, when I expressed my views about value investing being rigid, ritualistic and righteous and the absolute emptiness of virtue concepts like ESG and sustainability, but so be it. I am aware of things that I need to work on. My ego sometimes still gets in the way of admitting when I am wrong, I often do not let students finish their questions before answering them, I am sometimes more abrupt (and less kind) than I should be, especially when I am trying to get through material and my jokes can be off color and corny (as my kids point out to me). I do keep working on my teaching, though, and if you are a teacher, no matter what level you teach at, I think of you as a kindred spirit.  My Class Content     In my first two years of teaching, from 1984 to 1986, I was a visiting professor at the University of California at Berkeley, and like many visiting faculty around the world, I was asked to plug in holes in the teaching schedule. I taught six different classes ranging from a corporate finance class to undergraduates to a central banking for executive MBAs, and while I spent almost all of my time struggling to stay ahead of my students, with the material, it set me on a pathway to being a generalist. Once I came to NYU in 1986, I continued to teach classes across the finance spectrum, from corporate finance to valuation to investing, and I am glad that I did so. I am a natural dabbler, and I enjoy looking at big financial questions and ideas from multiples perspectives.          There are two core classes that I have taught to the MBAs at Stern, almost every year since 1986. The first is corporate finance, a class about the first principles that should govern how to run a business, and thus a required class (in my biased view) for everyone in business.  If you are a business owner or operator, this class should give you the tools to use to make business choices that make the most financial sense. If you work in a business, whether it be in marketing, strategy or HR, this class is designed to provide perspective on how what you do fits into value creation at your business. If you are just interested in business, just as an observer, you may find this class useful in examining why companies do what they do, from acquisitions to buybacks, and when corporate actions violate common sense.     The second is valuation, a class about how to value or price almost anything, with a tool set for those who need to put numbers on assets.  Again, I teach this class to a broad audience, from appraisers/analysts whose jobs revolve around valuation/pricing to portfolio managers who are often users of analyst valuations to business owners, whose interests in valuation can range from curiosity (how much is my business worth?) to the transactional (how much of my business should I give up for a capital infusion?)      While my class schedule has been filled with these two courses, I developed a third course, investment philosophies, a class about how to approach investing, trying to explain why investors with very different market views and investment strategies can co-exist in a market, and why there is no one philosophy that dominates.  My endgame for this class is to provide as unbiased a perspective as I can for a range of philosophies from trading on price patterns to market timing, with stops along the way from value investing, growth investing and information trading. It is my hope that this class will allow you to find the investment philosophy that best fits you, given your financial profile and psychological makeup.     In 2024, I added a fourth course to the mix, one centered around my view that businesses age like human beings do, i.e., there is a corporate life cycle, and that how businesses operate and how investors value them, changes as they move from youth to demise. I have used the corporate life cycle perspective to structure my thinking on almost every class that I teach, and in this class, I isolate it to examine how businesses age and how they respond to to aging, sometimes in destructive ways.     In my corporate finance and valuation classes, the raw material comes from financial statements, and I realized early on that my students, despite having had a class or two on accounting, still struggled with reading and using financial statements, and I created a short accounting class, specifically designed with financial analysis and valuation in mind. The class is structured around the three financial statements that embody financial reporting - the income statement, balance sheet and statement of cash flows - and how the categorization (and miscategorization) of expenses into operating, financing and capital expenses plays out in these statements. As many of you who may have read my work know, I think that fair value accounting is not just an oxymoron but one that has done serious damage to the informativeness of financial statements, and I use this class to explain why.     Since so much of finance is built around the time value of money (present value) and an understanding of financial markets and securities, I also have a short online foundational class in finance: As you can see, this class covers the bare basics of macroeconomics, since that is all I am capable to teaching, but in my experience, it is all that I have needed in finance.     As our access to financial data and tools has improved, I added a short course on statistics, again with the narrow objective of providing the basic tools of data analysis.  A statistics purist would probably blanch at my treatment of regressions, correlations and descriptive statistics, but as a pragmatist, I am willing to compromise and move along.          As you browse through the content of these classes, and consider whether you want to take one, it is worth noting that they are taught in different formats. The corporate finance and valuation classes will be taught in the spring, starting in late January and ending in mid-May, with two eighty-minute sessions each week that will be recorded and accessible shorts after they are delivered in the classroom. There are online versions of both classes, and the investment philosophies class, that take the form of shorter recorded online classes (about twenty minutes), that you can either take for free on my webpage or for a certificate from NYU, for a fee.  The accounting, statistics and foundations classes are only in online format, on my webpage, and they are free. All in all, I know that some of you are budget-constrained, and others of you are time-constrained, and I hope that there is an offering that meeting your constraints.     If you are interested, the table below lists the gateways to each of the classes listed above. Note that the links for the spring 2025 classes will lead you to webcast pages, where there are no sessions listed yet, since the classes start in late January 2025. The links to the NYU certificate classes will take you to the NYU page that will allow you to enroll if you are interested, but for a price. The links to the free online classes will take you to pages that list the course sessions, with post-class tests and material to go with each session: table.tableizer-table { font-size: 12px; border: 1px solid #CCC; font-family: Arial, Helvetica, sans-serif; } .tableizer-table td { padding: 4px; margin: 3px; border: 1px solid #CCC; } .tableizer-table th { background-color: #104E8B; color: #FFF; font-weight: bold; } ClassNYU Spring 2025 Online (free)NYU CertificateWhatsApp Discussion Group Corporate FinanceLinkLinkLink (Fall)Link ValuationLinkLinkLink (Spring & Fall)Link Investment PhilosophiesNALinkLink (Spring)Link Corporate Life CycleNALinkNALink AccountingNALinkNA  Foundations of FinanceNALinkNA  StatisticsNALinkNA The last column represents WhatsApp groups that I have set up for each class, where you can raise and answer questions from others taking the class. My Book (and Written) Content     Let me begin by emphasizing that you do not need any of my books to take my classes. In fact, I don't even require them, when I teach my MBA and undergraduate classes at NYU. The classes are self contained, with the material you need in the slides that I use for each class, and these slides will be accessible at no cost, either as a packet for the entire class or as a link to the session (on YouTube). To the extent that I use other material, spreadsheets or data in each session, the links to those as well will be accessible as well.      If you prefer to have a book, I do have a few that cover the classes that I teach, though some of them are obscenely overpriced (in my view, and there is little that I can do about the publishing business and its desire for self immolation.) You can find my books, and the webpages that support these books, at this link, and a description of the books is below: table.tableizer-table { font-size: 12px; border: 1px solid #CCC; font-family: Arial, Helvetica, sans-serif; } .tableizer-table td { padding: 4px; margin: 3px; border: 1px solid #CCC; } .tableizer-table th { background-color: #104E8B; color: #FFF; font-weight: bold; } Corporate Finance Valuation Investment Philosophies Corporate Life Cycle Applied Corporate Finance (Wiley, 4th Ed): This is the book that is most closely tied to this class and represents my views of what should be in a corporate finance class most closely. Investment Valuation (Wiley, 3rd Ed, 4th ed forthcoming): This is my only valuation textbook, designed for classroom teaching. At almost 1000 pages, it is overkill but it is also the most comprehensive of the books in terms of coverage. Investment Philosophies (Wiley, 2nd Ed): This is the best book for this class, and provides background and evidence for each investment philosophy, with a listing of the personal characteristics that you need to make that philosophy work for you. Corporate Life Cycle (Penguin Random House, 1st Ed): This is the most recent of my books and it introduces the phases of the corporate life cycle and why business, management, valuation and investment challenges change with each phase. Corporate Finance (Wiley, 2nd Ed): This is a more conventional corporate finance book, but it has not seen a new edition in almost 20 years. Little Book of Valuation (Wiley, 2nd Ed): This is the shortest of the books, but it provides the essentials of valuation, and at a reasonable price. Investment Management (Wiley, 1st Ed): This is a very old book, and one that I co-edited with the redoubtable Peter Bernstein, focused on writings on different parts of the investment process. It is dated but it still has relevance (in my view).   Strategic Risk Taking (Wharton, 1s Ed): This is a book specifically about measuring risk, dealing with risk and how risk taking/avoidance affect value. Dark Side of Valuation (Prentice Hall, 3rd Ed): This is a book about valuing difficult-to-value companies, from young businesses to cyclical/commodity companies. It is a good add-on to the valuation class. Investment Fables (FT Press, 1st Ed): This book is also old and badly in need of a second edition, which I may turn to next year, but it covers stories that we hear about how to beat the market and get rich quickly, the flaws in these stories, and why it pays to be a skeptic.     Damodaran on Valuation (Wiley, 2nd Ed): This was my very first book, and it is practitioner-oriented, with the second half of the book dedicated to loose ends in vlauation (control, illiquidity etc.)       Narrative and Numbers (Columbia Press, 1st Ed): This was the book I most enjoyed writing, and it ties storytelling to numbers in valuation, providing a basis for my argument that every good valuation is a bridge between stories and numbers.        Finally, I discovered early on how frustrating it is to be dependent on outsiders for data that you need for corporate financial analysis and valuation, and I decided to become self sufficient and create my own data tables, where I report industry averages on almost every statistic that we track and estimate in finance. These data tables should be accessible and downloadable (in excel), and if you find yourself stymied, when doing so, trying another browser often helps. The data is updated once a year, at the start of the year, and the 2025 data update will be available around January 10, 2025. A Class Guide     I would be delighted, if you decide to take one or more of my classes, but I understand that your lives are busy, with jobs, family and friends all competing for your time. You may start with the intent of taking a course, but you may not be able to finish for any number of reasons, and if that happens, I completely understand. In addition, the courses that you find useful will depend on your end game. If you own a business, work in the finance department of a company, or are a consultant, you may find the corporate finance course alone will suffice, providing most of what you need. If you are in the appraisal or valuation business, either as an appraiser or as an equity research analyst (buy or sell side), valuation is the class that will be most directly tied to what you will do. I do believe that to value businesses, you need to understand how to run them, making corporate finance a good lead in. If you plan to be in active investment, working at a mutual fund, wealth management or hedge fund,  or are an individual investor trying to find your way in investing, I think that starting with a valuation class, and following up with investment philosophy will yield the biggest payoff. Finally, the corporate life cycle class, which spans corporate finance, valuation and investing, with doses of management and strategy, will be a good add on to any of the other pathways, or as a standalone for someone who has little patience for finance classes but wants a framework for understanding businesses. As a lead-in to any of these paths, I will leave it to you to decide whether you need to take the accounting, statistics, and foundations classes, to either refresh content you have not seen in a long time or because you find yourself confused about basics: If you find yourself overwhelmed with any or all of these paths, you always have the option of watching a session or two of any class of your choice. As you look at the choices, you have to consider three realities.  The first is that, unless you happen to be a NYU Stern student, you will be taking these classes online and asynchronously (not in real time). As someone who has been teaching online for close to two decades now, I have learned that watching a class on a computer or display screen is far more draining than being in a  physical class, which is one reason that I have created the online versions of the classes with much shorter session lengths.  The second is that the biggest impediment to finishing classes online, explaining why completion rates are often 5% or lower, even for the best structured online classes, is maintaining the discipline to continue with a class, when you fall behind. While my regular classes follow a time line, you don't have to stick with that calendar constraint, and can finish the class over a longer period, if you want, but you will have to work at it.  The third is that learning, especially in my subject area, requires doing, and if all you do is watch the lecture videos, without following through (by trying out what you have learned on real companies of your choosing), the material will not stick.     I will be teaching close to 800 students across my three NYU classes, in the spring, and they will get the bulk of my attention, in terms of grading and responding to emails and questions. With my limited bandwidth and time, I am afraid that I will not be able to answer most of your questions, if you are taking the free classes online; with the certificate classes, there will be zoom office hours once every two weeks for a live Q&A. I have created WhatsApp forums (see class list above) for you, if you are interested, to be able to interact with other students who are in the same position that you are in, and hopefully, there will be someone in the forum who can address your doubts. Since I have never done this before, it is an experiment, and I will shut them down, if the trolls take over. In Closing…     I hope to see you (in person or virtually) in one of my classes, and that you find the content useful. If you are taking one of my free classes, please recognize that I share my content, not out of altruism, but because like most teachers, I like a big audience. If you are taking the NYU certificate classes, and you find the price tag daunting, I am afraid that I cannot do much more than commiserate, since the university has its own imperatives. If you do feel that you want to thank me, the best way you can do this is to pass it on, perhaps by teaching someone around you.  YouTube Video Class list with links Corporate Finance (NYU MBA): https://pages.stern.nyu.edu/~adamodar/New_Home_Page/webcastcfspr25.htm  Valuation (NYU MBA): https://pages.stern.nyu.edu/~adamodar/New_Home_Page/webcasteqspr25.htm  Corporate Finance (Free Online): https://pages.stern.nyu.edu/adamodar/New_Home_Page/webcastcfonline.htm  Valuation (Free Online): https://pages.stern.nyu.edu/~adamodar/New_Home_Page/webcastvalonline.htm  Corporate Finance (NYU Certificate): https://execed.stern.nyu.edu/products/corporate-finance-with-aswath-damodaran  Valuation (NYU Certificate): https://execed.stern.nyu.edu/products/advanced-valuation-with-aswath-damodaran  Investment Philosophies (Free Online): https://pages.stern.nyu.edu/~adamodar/New_Home_Page/webcastinvphil.htm  Investment Philosophies (NYU Certificate): https://execed.stern.nyu.edu/products/investment-philosophies-with-aswath-damodaran  Corporate Life Cycle (Free Online): https://pages.stern.nyu.edu/~adamodar/New_Home_Page/webcastCLC.htm  Accounting 101 (Free Online): https://pages.stern.nyu.edu/~adamodar/New_Home_Page/webcastacctg.htm  Foundations of Finance (Free Online): https://pages.stern.nyu.edu/~adamodar/New_Home_Page/webcastfoundationsonline.htm  Statistics 101 (Free Online): https://pages.stern.nyu.edu/~adamodar/New_Home_Page/webcaststatistics.htm
