About this author:
The S&P 500 PE ratio is an important determinant of the value of the stock market and the trend of the S&P 500. Historically, the S&P 500 PE ratio has a median of 15.7. Today, the S&P PE ratio is 139 based on a closing price of 1,044 on Friday, September 11, 2009. This assumes the trailing earnings for the S&P 500 companies as reported by Standard & Poor’s for the four quarters ending June 30, 2009. A PE ratio at 139 is not sustainable. What is a reasonable PE ratio for the S&P 500 given our current situation?
The S&P 500 PE ratio reflects the performance expectations of the stock market. In the last three quarters, the PE ratio has leapt higher with the plunge in earnings of the S&P 500 companies. The fall in earnings overcame the drop in the value of shares in early March 2009.
Even with the recovery in the markets since the lows in March, the S&P 500 PE ratio remains very high as the trailing four quarters of earnings is so low. According to data from Standard & Poor’s on the S&P 500, as reported earnings for 99% of all reporting companies, creates an S&P 500 PE ratio of 122.41 as of June 30, 2009. The trailing four quarters of earnings was $7.51. Two years ago the as reported earnings for the S&P 500 companies was $84.92 for the quarter ending on June 30, 2007. The S&P 500 PE ratio was 17.70. This plunge in earnings is what caused the S&P 500 PE ratio to rise so high.
As shown on the chart below the S&P 500 PE ratio rose to 122 for the quarter ending June 2009. The estimates through the end of 2010 are from Standard & Poor’s for earnings and the S&P PE ratio.
The U.S. has had three recessions since 1988 according to the National Bureau of Economic Research, the group that determines when the U.S. has had a recession. These recessions are depicted in red in each of the charts shown here.

S&P 500 Earnings Forecast
Standard & Poor's has forecast earnings through the end of 2010. The chart below shows actual trailing annual earnings since the June 1990 through June 2009. It also includes the forecast for earnings through December 2010.
What stands out is the sudden jump in earnings that begins with the quarter ending December 2009. Part of this sudden change is due to the large drop in earnings reported for December 31, 2008. For the quarter ending December 31, 2009 the S&P 500 delivered $23.25 in losses for that quarter alone due to the large write-offs in the financial sector.
Once the major write-offs are no longer part of the four quarter trailing earnings, the annual earnings return to a forecasted $41 to $45 range for the S&P 500. This earnings forecast provides a basis to project what the S&P 500 index could achieve over the next 12 - 15 months.
S&P 500 Trailing annual earnings
Is the S&P 500 Going Higher or Lower
In the recession of 1990 – 1991, the S&P index began to climb before the end of the recession. Following the end of the 2001 recession, the S&P 500 fell another 200 points before rebounding. So far in the recession of 12/2007 - ?, the S&P 500 fell significantly and has turned up through June 2009. We know it is trading above 1,000 as of the middle of September 2009.
S&P 500 Index history and Forecast
Looking at the earnings forecast from Standard & Poor’s we can assess which way the S&P 500 will likely move for the remainder of 2009 and all of 2010.
The table below uses the trailing four-quarter earnings from Standard & Poor’s. It then applies a PE ratio to derive the S&P 500 index forecast. When looking at the table, keep in mind that the median PE ratio is 15.7. In addition, the PE ratio is mean reverting, so we should expect it to fall further, possibly to 15 or lower. The very low S&P trailing earnings for June and September 2009 are due to the large loss reported in December 2008 quarter.
S&P 500 index forecast table
Using the December 2009 quarter the earnings forecast $39.35 and a PE ratio of 30 gives us a target price for the S&P 500 index of 1,181. On Friday September 11, 2009, the S&P closed at 1,044. A PE ratio of 25 gives us an S&P 500 index of 984. If the S&P 500 PE ratio remains between 25 and 30, we should see the S&P 500 index climb to a range of 1,146 to 1,375.
This examination of earnings and S&P PE ratios is telling us to expect a higher S&P 500 index throughout 2009, as long as the PE ratio remains in the 25-30 range. Whether this is correct, depends on several factors. First, are the earnings forecast correct? Investors should monitor earnings expectations throughout the year, looking for any changes either up or down. The estimates for all of 2010 are higher now than they were in June, indicating S&P is expecting a more robust recovery.
Second, evaluate your PE ratio assumptions based on the outlook for the economy and the markets. If earnings are running above the forecast from Standard & Poor’s, then you should could expect the PE ratio to hold in the 25 - 30. On the other hand, if earnings expectations are falling, then you should expect the PE ratio to fall further. In each case, any move in the PE ratio will cause a significant move in the S&P 500 index.
Yale University Professor Robert J. Shiller, author of Irrational Exuberance: Second Edition uses a modified PE ratio that smoothes out the volatility in the ratio. The denominator of this modified ratio is average inflation-adjusted earnings over the trailing 10 years. Shiller calls this modified ratio "p/e10." Using this data the modified ratio “p/e10” produces a PE ratio of slightly over 15, which is very close to the median of 15.7. In December 2007, the beginning of the current recession, the “p/e 10” was 25.95. Since markets tend to cycle above and below the median, we should expect the “p/e 10” to fall further before turning back up.
Using December 2009 trailing four-quarter earnings of $39.95 times the median PE ratio of 15.7 gives us an S&P 500 index of 627. This gives us a range for the S&P index of a high of 1,375 assuming an S&P PE ratio of 30 to a low of 675 with a PE ratio of 15.7, the median. The risk is to the down side.
Investors still need to understand if the S&P 500 PE ratio will rise or fall. If Professor Shiller is correct, then we should look for a drop in the S&P 500 PE ratio. On the other hand if the current PE ratio remains in the 25 - 30 range, then we could see the S&P 500 index rise further driven only by higher earnings.
For investors a PE ratio in the 25 to 30 range means it will be difficult to find bargains, as you cannot expect an expansion of the PE ratio to contribute a higher level on the S&P 500 index. Moreover, there is a risk the S&P PE ratio could contract, causing the level of the S&P 500 index to fall. A drop to 20 on the S&P 500 PE ratio gives us a high of 917 on the S&P 500, assuming earnings does not change from its forecast. Going forward investors need to keep in mind that the risk of a PE ratio contraction is a possibility. A rise in the S&P 500 PE ratio is unlikely.

    The Shiller PE is reasonable, but the 139 PE is nonsense. Even S&P doesn't understand how to calculate its own index' earnings(alphaninja.blogspot.co...).

    The 139 PE logic would be similar to owning $90 of a stock with a 15PE and $10 of a stock with a 200PE and saying your portfolio had a PE of 107. S&P lets a company with almost zero weight in their index wipe out the same dollar amount of earnings of a company with 100times the weight. It's amazing that they get it so wrong.

    S&P PE ratio of 139 might not be sustainable if there was no Government intervention. But there is enormous Government Intervention in free market economy...

    So, in my opinion, if the S&P falls 15-20% from here on growth worries, one might see more quantitative easing and packages which would further help boost the markets in a weak economy...

    In my opinion, in a market where there is Government intervention, there is no relation at times between stock markets and economy and also valuation...

    The government and the media have persuaded a lot of investors that the economy is going to get a lot better. And that's why S&P 500 is pricing in a V-shaped recovery in the earnings of companies.

    Since the future doesn't yet exist, only imagination is the limit when it comes to predicting the future. But eventually the future becomes present. And when that happens, then everyone realizes just how true and realistic their imagination of the future has been.

    The thing to keep in mind about analysts and investors is that once in a while they are prone to have irrational exuberance. They start predicting a far brighter future than the one that's likely to come about. And this leads to a big disappointment, when the future arrives and it isn't nearly as good as everyone was expecting.

    Most people, who are predicting a bright economic future now, have a very poor record of predicting the future accurately. And relying on their optimistic predictions now is no better than gambling.

    Whether the "real" PEs hover nearer 139 or nearer 19 isn't the issue. Americans have been fooled by brokers on Wall Street and baby-kissers in DC long enough. We are, collectively, paying down debt and saving for the future at a record rate. This does NOT bode well for those expecting rapidly-increasing revenues and earnings and "business as usual." Paying a premium for growth only pays if the growth is there.

    Of course, if you see this all too clearly, Wall Street will always give you a pair of rose-colored glasses. Free.

    the whole P/E is messed up.. It is a floating multiple you can't really argue with the market until it is proven wrong right? If going forward there's 70 EPS expected in 2010, that with a historical 15 multiple it is where we are trading today 1,050..

    1. When excess liquidity starts to distort markets and economies, it starts with the easiest, most manipulable, target: financial markets esp. stock markets where Govt impelled perversities and asymmetries already exist. Bubbles and bubble makers do not care about P/E ratios or cash flow or revenues or any other valuation ratio: they care about the forced bidding up of targeted assets.
    Any market index, when divorced from investor rationality or asset pricing logic, becomes a metric of willful delusion combined with deliberate distortion and force fed by a vast amount of nearly free money concentrated in the hands of the most active(and politically anointed) traders.

    2. When ordinary investors have already experienced a lost decade,or worse, in their financial portfolios , are unable to get a return on cash or near cash assets and are very nervous about real estate investing , they become very susceptible to desperation about "making up" the loss in their financial assets(fear governs) and very anxious to find yield or capital gains somewhere, anywhere(greed governs). This is the case at present.
    Combine the fear and greed of ordinary investors with the manifold corruption and deceits of Wash DC and Wall St and the complicit propaganda of the MSM(big recovery already here: get in now, get in big or be left behind and look very foolish; investment opportunity of a lifetime: one and only chance to make up for the lost decade) and ordinary investors can be herded into a financial box canyon with laughable ease. Once in the canyon they can be conveniently and massively slaughtered-----yet again.

    ttc Fed chairman Ben Bernanke say the recession is “technically” over. This will be great news for the people living in the tent city under short finals who I fly over when I land at Buchanan airport. It means “technically” they will eat tonight. It will also be welcome to the 18% of the workforce who are now unemployed in California, the 1.5 million who are losing unemployment benefits in the next three months, and one million college students who ran up and average $30,000 in debt to graduated this year so they could sleep on their parents’ sofa. Traders celebrated the news by running the S&P 500 up to 1,054, a positively nose bleeding 58% above the March 9 low. Apparently, the stock market thinks Obama is the greatest president in history, rising some 40% since the inauguration, compared to a 30% drop during the eight years of Bush rule. That is some report card. Too bad we can’t annualize that. The only thing I approve of today is that this love fest took silver to a new high this year of over $17.

    User 353732 - Well written comment that is right on the mark.

    Cru Jones - So, you don't think S&P knows how to calculate a P/E ratio? Let's see, they divide the total price of one share of stock for each company in the index and divide that by the total amount of earnings for one share of stock outstanding for all of the same companies. Bigger companies tend to have a lot more shares outstanding and therefore higher capitalizations. Thus, their earnings per share have a much higher weighting than the smaller companies that have fewer shares outstanding. The multiple is a simple measure of how much an investor is willing to pay for a given amount of earnings. The weighting isn't exactly perfect, but it does weight large cap stocks much, much more highly than relatively smaller cap stocks within the index. It does not, as you indicate, weight all stocks and earnings evenly. Remember, we are talking about the amount of earnings "per share" for a company. Weighting is accomplished by the variance in numbers of shares outstanding. Are you willing to pay more for $1 dollar of earnings of a big company than for a $1 of earnings of the smaller company with greater growth prospects? I hope not.

    I tend to ignore the P/E debates since there are too many ways of looking at it. Frankly, cash flow is king - and the balance sheet is going to be king, especially with the financials.

    Too many ways to distort the E.

    CruJones has a reasonable point; it was an observation made in a WSJ op-ed by Jeremy Siegel (online.wsj.com/article...)

    S&P ignores market caps because of the way it aggregates the earnings of all members of the index. If Exxon earns $10B for the quarter, and Jones Apparel loses $10B, the aggregate earnings - using S&P's methodology - will be $0. The only time market cap comes into play is during the calculation of the actual index value; a rise in Exxon's stock will affect the index more than the same percentage movement in Jones Apparel's stock.

    I won't argue that finding the "perfect bargain" in today's market may be difficult; however, when is there ever such a thing?

    I use the P/E ratio as a secondary indicator for buying and selling stocks but I don't use the ratio in the same a manner as many value investors teach. I will explain the difference in my methodology for using the P/E ratio to your advantage.

    Many value investors will pass on a growth stock that has a P/E ratio higher than a predetermined level. For example, they may discard all stocks that have a ratio of 15 or higher, no matter what industry group they come from. Some investors will discard any stocks that have P/E ratios above the industry group averages, concluding that they are grossly overvalued. I am not saying that this method doesn't work, because it does but it will not work when you focus on buying young innovative small cap stocks that are growing at tremendous rates, rates that "big caps" can no longer sustain.

    I have never passed on buying a stock due to its P/E ratio being too high. What is too high? Too high to one investor may be low to another investor. This is the same logic that I use when speaking of stock’s prices. One problem that have with some value investors is their lack of understanding of the movement of the P/E ratio line on a chart. As a stock begins to move 100% or 200% from its pivot point, the P/E ratio will also move higher over the course of time. Plotting the P/E ratio on a chart will show you how much of a gain the ratio has made as the stock continues its up-trend.

    It isn't about calling the S&P one company. It is the fact that you can have an index of 10 companies with 9 of them making money and one that had a huge write down for 1 quarter, and while the other 9 have very low PE ratios, the index ratio comes out very high because of the one company that lost money during 1 quarter. Obviously that is a severe flaw that this article does a good job explaining. It is amazing how many allegedly intelligent investors out there have been duped by this number lately.

    No, that is only the reason the P/E increased! As you know the S&P P/E is calculated by dividing the current S&P value by the sum of the last 4qtr earnings.
    In other words, come 1st qtr 2010, when the 4th qtr 2008 are no longer included, the P/E will 'suddenly change' back to it's normal range. Investors must always remember the P/E is a trailing indicator.

    "Part of this sudden change is due to the large drop in earnings reported for December 31, 2008. For the quarter ending December"

    Agree, P/E is quite a distorted indicator, it can be read or interpreted a million different ways, and rarely a good indicator for the next 3months - actually quite a poor one.

    When Ebay or Yahoo were trading at P/E ratios around 150, in late 90s, it eventually collapsed later to low double digit, exept that in between, it went to 300 first.

    I'd rather ride, and let the Bear write...

    OK, fatal mistake in looking at that index P/E because it includes companies that are making losses, which distorts the P/E ratio much higher. As you know P/E's on a loss making companies are not meaningful. Last time I looked, Citigroup and General Motors were the main culprits distorting the index P/E.

    A more meaningful index p/e is calculated by excluding any loss making companies (because these distort the p/e much higher).

    ** This is currently at 15.9x forward earnings for S&P500. **

    I guess you also have to take into consideration that the index does have loss making companies in it but this calculation at least gives you a meaningful figure of what multiplier is being applied to the profitable stocks.

    Mr. Wagner, it seems you would agree that for one to believe that 139 is a real number (cell H50 in S&P's earnings spreadsheet), one also must believe that the as-reported earnings for Q4 2008 of -23.25 (NEGATIVE TWENTY-THREE AND TWENTY-FIVE) (cell D54 of S&P's spreadsheet) is also real.

    I offer that cell D54 is a black swan freak and that the market correctly dismissed it as such. Did the editors choose your headline for you? If not, why the disconnect between the reasonably balanced article, and the hysterical headline?

    PEs do spike at the turning of recessions. The E is depressed, but the P expects dramatic improvement into the future as the economy recovers.

    So the median trailing 4-quarter P/E ratio of the S&P500 is 15.7? Are you sure about that (meaning that median is based on trailing 4 quarters as opposed to a longer time-frame or projected future earnings for example)? Where is that data from?

    Mr. Wagner, the author, walked right into a hornet's nest when he brought up the subject of the S&P's PE ratio. I know, because I walked into the same hornet's nest a few months ago and emerged alive, but with lots of stings.

    The article is essentially correct. So are some of the comments, while others suggest that the writer does not know how the S&P computes the PE of its own index.

    To be honest, after months of off-and-on study, I'm not sure whether the PE computed by the S&P is correct or not, nor whether it is helpful or not. However, I do know this:

    (1) The way S&P computes its PE is open to honest debate. Siegel (later joined by Shiller) brought this up in February, creating a debate that forced S&P to defend itself. The brouhaha has died down, but the issue is still real. I think Siegel is right, but I'm not positive.
    (2) The often-quoted "earnings of the S&P 500" is a highly massaged number. It is not the actual total earnings (which are available on a separate page in the S&P spreadhseet, labeled "Issue Level Data"). S&P has to massage the numbers so that, when they replace a stock in the index, it doesn't create a discontinuity in the index's value.
    (3) S&P has replaced about 40 companies in the last 12 months.
    (4) Therefore, many of the companies presently in the index did not contribute to the TTM "earnings" that S&P uses in computing its own current PE. They do not go back and restate past earnings to reflect later changes in the index's companies. Once they close out a quarter's "earnings," that number is locked in forever.
    (5) Everyone who noted that the current PE is grossly distorted by Q4 2008, when many banks took massive write-offs against toxic loans, is correct. And many of those companies are no longer in the index.
    (6) It is a philosophical question what the PE of an index should be, anyway. Should it be the median PE of all companies in the index? The arithmetic average? Should it be weighted in the same way that S&P weights the companies in computing the index itself? Should it be equal-weighted? All of these could have arguments made for them.
    (7) In computing the PE, S&P substitutes the value of the index for "P," price. So you have a derivative number, the index value, standing in for P, and another derivative number, the masssaged "earnings," standing in for E, in the equation P/E. Does this make any sense at all?
    (8) Last one: The PE is based on TTM "earnings" and current "price." It is backwards-looking. Is that helpful for forward-looking investment decisions? When someone blithely says the PE is not sustainable, or has not dropped to the typical lows of 8 or 9 seen in previous recessions, does that matter at all?

    This is ludicrous waste of time. What is the real world P/e of: Kimberly Clark? Cisco? Micosoft?

    Dude all these S&P stocks are trading at the same price as *after* the planes hit the WTC on 9/11 and all have much higher earnings today than they did in 2001. And today the discount rate is zero.

    Get with the program by using some common sense. The market has problems but valuation of blue chip S&P stocks is not one of them.

    Putting any minor data massaging aside, the S&P, by its own admission, treats their estimation of the P/E of the index EXACTLY like a single corporation with 500 divisions. The index is maket cap weighted (the total share count is irrelevant). This allows the following simple calculation of P/E.

    Add up the day's market cap of all 500 stocks, then add up all of the earnings (trailing 12 month for example); then divide the market cap sum number by the total earnings number. So large earnings losses in one or a few companies can have a huge impact on index earnings, just like when the losses at the Financial Products div. of AIG wrecked their corp. earnings.

    But the S&P500 is effectively a portfolio of stocks, NOT a single corporation. So the index actually has the full benefit of its diversification unlike a single corp. with a diversified group of divisions. When my tiny position in General Motors went to zero, it had little impact on my portfolio value regardless of how big GM's losses were last year.

    So yes, S&P's cute P/E listing is just as stupid, incompetent, and misleading as the activities of their bond rating group. Figuring P/E of the whole index in a severe recession environment is a nonsensical exercise.

    The right way to approach this is to estimate a reasonable multiple for each industry and multiply it by the EPS of each company to get an effective target price. In some cases this target price will be zero, but never negative! Then a "fair value" for the S&P500 can be obtained from a market cap weighting of these 500 target prices and compared to the market value of the index. But hey, this would be a lot of work for a bunch of underpaid analysts.

    While I think the S&P PE ratio is a seriously flawed tool for index valuation (at least at any time when any of the companies in the index have had unusual write offs during the previous year), the earnings portion could be quite useful in monitoring broad economic activity. I suspect that it is a very sensitive barometer of GDP growth/contraction.

    User 353752 - good post to which I will add one of the means which the pumpers have employed in the past which, although no longer particularly effective, were most arguably a significant part of the price appreciation methods used starting in 10/2002, i.e., "outside the inside" trading. This method, to post on NASDAQ, which took no responsibility for allowing the executions to be promulgated, a price of an execution between the fabled and often glorified "willing buyer"and "willing seller" who were not to be identified (without the expensive and time-consuming process of legal discovery; aguably NASDAQ helped the alleged perpetrators to cover their tracks at every turn by never identifying the traders or what role,principal or agent, they played, or provided the available concentration ratios, i.e., what the concentration of ownership of the equity was at every moment in the period of the extraordinary trade, i.e., "outside the inside" posted executions, the volume of trades, both ticks and number of shares transacted in given time frames, and the resulting momentum price moves subsequent to the trades being promulgated; note, price execution/promulgation at higher than most recent highs resulted in subsequent price movement based on facilitating momentum created by posting a higher high than the previous high trades but executed without a corresponding "asked" greater than the previous high, i.e., an outside the inside trade.

    Using 100 share lots to pump up prices the "willing buyer" and "willing seller" were able to create virtually any price it wished in targeted equities chosen on the basis of daily volume, price, short ratio, float and trading characteristics. By selectively identifying a target equity, the "traders" could dedicate not more than $10 Million of trading capital to achieve their objectives.

    Then "back box" operators conducted their business very differently from the ultra-high frequency trading of today but did rely on speed of execution and the willingness of the NASDAQ, the association, to tolerate what the "traders" were doing. These trades provided income for a large variety of street folk, from the clearing firms to the investment banks seeking additional business from good results for a potential or actual client, to the brokerages and the trading firms acting as agents and of course the principals owning the equities, the allotments, the warrants, et al.

    The most significant difference between the 2002-2008 market and today's market is the arguable collusion of the federal government in manipulating equity price by providing the POMO and other funds to the traders at near costless basis. At least in 2002 with Greenspan opening the floodgates of liquidity and the association and exchanges giving a free hand to the traders, rationality simply was altered and the then existing bubble was rapidly expanded and developed as a sustainable economic factor, until it burst.

    NASDAQ may still have the trade, concentration ratio and other execution related data in its gargantuan databases. If someone would like to pursue this thread contact me at valleyma@comcast.net. I will provide what information I have. The truth, I believe, about equity price manipulation in that prior bubble period starting in 10/2002 can be unearthed by a rigorous review of the data, if it can be obtained.

    Why is it a severe flaw if the high PE ratio is indicative of companies losing money?

    I'm in agreement that P/E is a somewhat flawed valuation tool. But you have to at least use future earnings estimates. Price is governed by the investors' expectation of future earnings, so why would backward P/E's give any meaningful insight? Of course the backward P/E will be ridiculously high in a quick recovery scenario.

    Anyone who cites an S&P500 p/e of 139 as a meaningful figure should NOT be writing commentaries on the market!

    Is this (a) a joke, (b) a typo, or (c) a government conspiracy?

    The correct answer is c.

    I don't understand how Shillers modified ratio "p/e10." formula is better. It understates values when economies are growing and overstates values when economies are contracting. Can anyone tell me how that is a superior evaluation tool?

    Confusing article with a wide predictive range, would have been good to put a stake in the sand based on the analysis. How about analyzing how the PE ratio performed over the last century of recessions?? Also, who can trust earnings with mark to market rules, write-offs, or sidelining losses to future quarters...I wish I could sideline bills and make myself feel richer!!

    I imagine the S&P 500 P/E ratio was lower when the banks were reporting great earnings a few years ago but we all know that those earnings weren't real. At least now we have a ratio that might be more meaningful.
