# S&P 500 P/E Ratio, Earnings and Valuation Analysis

IS THE S&P 500 INDEX A GOOD INVESTMENT AT THIS TIME? (March 25, 2018)

What Return Can You Reasonably Expect From Investing in the S&P 500 Index?

This article is your One-Stop Page to Understand The S&P 500 Earnings and Dividend Yield and how these relate to The Fair Value of The S&P 500 Index.

This short article (which draws on Warren Buffett’s teachings1) provides:

1. Calculations of the current  fair value of the S&P 500 index based on several scenarios
2. The Expected next 10-year average Return per Year from the S&P 500 based on earnings growth and terminal P/E Assumptions.
3. The S&P 500 index  P/E ratio (based on trailing and forward earnings)
4. Earnings and earnings yield on the S&P 500 index (GAAP, operating and forward earnings)
5. Dividend Yield on the S&P 500 index
6. A link to the source for all the S&P 500 data on the the Standard and Poors web site
7. The Exchange Traded Fund (ETF) symbols to use to invest in the S&P 500 index

Mathematically, the Fair Value of the S&P 500 Index can be defined based on just four things: the return that investors require, the current earnings and dividend level, the expected growth in earnings and dividends, and the probable P/E ratio that the index can be expected to be sold for at the end of a reasonable holding period of say 10 years.

This article provides a range of values depending on the scenario chosen. I believe that the analysis indicates that a conservatively calculated fair value for the S&P 500 Index is within the range of 1990 (for required expected return of 7%) to 2165 (for required expected return of 6%), with a midpoint estimate of 2078 (for required expected return of 6.5%). My assumption for this estimate is that the S&P normalized earnings and dividend will grow with GDP at about 4% per year (that is 4% nominal GDP growth such as 2% real growth and 2% inflation) and sell at its long-term average P/E of 17 in ten years.

Given an S&P level of 2588 at the time of this analysis, my fair value estimate may seem to be impossibly pessimistic. I would say it might be on the conservative side by assuming that the market P/E will return to 17 in ten years time. I could easily calculate that the S&P 500 is fairly valued if I assumed that the P/E will remain well above 20 or that earnings (which I already adjusted upwards by 10% to reflect the lower income tax rates for 2018) are currently abnormally low and about to surge. I have chosen to maintain a somewhat conservative approach. But I do not think that my assumptions are in anyway radically pessimistic.

You can compare my fair value estimate of 2078 to the current S&P 500 level which is available here.

This analysis is dated March 25, 2018. However the calculated fair value of the S&P 500 index is not affected by the precise date of the analysis and my fair value estimate of 1990 to 2165 with a mid-point of 2078 will not change until at least after the next set of actual and/or forecast quarterly earnings numbers becomes available, and even then will not change much. As of March 25, 2018, the S&P 500 index at 2,588 appeared to me to be about 25% over-valued, as a point estimate, based on a long-term investment and based on reasonably conservative (but not pessimistic) assumptions. However, if it is assumed that interest rates will remain very low and investors require only an expectation of a 6% (pre-tax, pre-costs) return from equities and that a P/E of about 19 will apply in ten years and that earnings per share growth will average 5% then the S&P 500 could be considered to at fair value. And it could be considered under-valued if one assumes much more rapid growth and a terminal P/E of 20 or higher or if one assumes that the trailing year earnings should have been adjusted up even higher to reflect the income tax cuts. But those are aggressive assumptions and I consider the S&P 500 index to be clearly over-valued at this time.

Nevertheless, the analysis suggests that investing in the S&P 500 will provide a positive although modest return over the next ten years under even the more pessimistic scenarios shown.

ANALYSIS

A quick indication of whether or not the S&P 500 index is fairly valued is provided by simply looking at its P/E ratio. As of March 25, 2018, the S&P 500 was at 2588 and had a P/E ratio of 23.6. This is based on actual reported earnings in 2017 of \$109.88

This is 40% higher than the historical average P/E ratio of 17.0. However, today’s record low interest rates support a P/E ratio somewhat higher than the historic average. Still, the quick indication is that the S&P 500 index is overvalued at this time at 2588 However this might be jumping to conclusions. We have to consider whether the recent earnings level on the index are at a normal level and what the outlook is.

This article explores the question of the estimated fair value of the S&P 500 index in much more detail below.

Importantly, an analysis of the fair value of the S&P 500 index will not likely provide a short-term indicator of market direction but it should provide a long-term indicator of the expected return from investing in the S&P 500 index at this time.

The attractiveness of the S&P 500 index level can be judged by looking at the current level of earnings and dividends of the S&P 500 index stocks, projecting the future rate of earnings and dividend growth and by considering the minimum return required by investors. Analysts often apply valuation techniques to individual stocks. It is actually far easier to apply these calculations to a stock index since an index constitutes a portfolio and therefore its diversification eliminates much or most of the random noise of unexpected events. Still, many challenges remain in applying this analysis and its results, while providing some indication for the long-term, can offer no insight for the short-term. The index remains vulnerable to changes in interest rates and to growth in the economy but is usually largely insulated from the numerous random events that can impact an individual stock.

What is the Earnings and P/E ratio on the S&P 500 index right now? (March 25, 2018 with the index at 2588)

Data from Standards and Poors itself provides no less than four quite different answers to the above question based on different views of the earnings on the S&P 500 index.

When you ask the “simple” question of “what is the earnings on the S&P 500?” index or “what is its P/E ratio?” you are given a number of quite different answers. We can help you fully  understand the different answers.

Standard and Poors itself in its “The Outlook” publication focuses on the forecast year (called forward) operating earnings scenario, summed by individual company which is usually the highest earnings number and lowest P/E forecast. I find that to be overly aggressive as it ignores all unusual losses. (Surely on a group of 500 companies a certain amount of so-called “unusual” losses is to be expected every year and should not be ignored).

As of  March 25, 2018, the S&P 500 index was at 2588 and had a trailing Price Earnings Ratio (“P/E”) of 23.6 (the historical average is 17.0) based on actual trailing reported earnings and had a current Dividend yield of 1.99%  The trailing P/E based on the past 12 months operating earnings (eliminates unusual one-time items) was more attractive at 20.8.  The forward S&P 500 P/E ratio based on projected reported actual accounting GAAP earnings in the next 12 months, which call for a 31% increase!, was at 17.8. The forward P/E based on a forecast or forward operating earnings in the next 12 months (eliminates all unusual one-time items) was at 17.0 (based on the weighted sum of individual company forecasts). The forecast calls for an increase in operating earnings of 25%.

Most analysts might focus on forecast operating earnings for the index (P/E of 17.0) as the best estimate since it eliminates unusual gains and losses and is future oriented.

Given that projected earnings tend to be optimistic and to ignore all “unusual” losses, I normally prefer to simply use the actual trailing P/E, or equivalently the actual trailing GAAP earnings level.  This figure is \$109.88, for a P/E of 23.6. It is important to understand that this starting earnings level is a very major determinant in my calculation of the fair value of the S&P 500 index and that it can be a difficult number to estimate if the actual trailing earnings is not judged to be at a “normal” level. Based on the graphs below, I would normally judge the trailing GAAP earnings to be representative of a normalized level. The latest 12 months earnings were approximately along the trend line. However, entering 2018 we have the special situation of a massive cut in U.S. federal income taxes. Analysts appear to expect a massive 31% earnings increase in 2018. My own view is that some of the tax cuts will show in higher wages and competitive price reductions rather than in earnings. I will add 10% to the actual 2017 earnings and therefore estimate the normalized 2017 GAAP earnings level to be \$121.

The S&P 500 index represents a portfolio of 500 stocks. For each \$2588 (the index value)  purchased, the underlying companies in the portfolio were recently earning (normalized for the tax reduction) \$121 per year and currently paying an annualized dividend of \$2588 * 0.0199 = \$51.50.

When we buy the S&P 500 index, we can therefore think of it as being an investment or “stock” that (as of March 25, 2018) costs \$2602 and currently earns about \$121 per year (depending on the impact of the income tax cuts)  and pays a current dividend of \$51.50 per year. It is worth thinking about whether or not this “stock” or “business” is a good investment at or around its recent level of \$2588.

We know that the S&P 500 index was at 2,588 on March 25, 2018. We can estimate what the S&P theoretically “should” be trading at based on the value of its current earnings and dividends and the projected growth in those earnings and dividends. This intrinsic value approach calculates the value of the projected earnings and dividends for a ten year period and then assumes that the index is sold at some projected future P/E ratio.

In addition to the beginning earnings and dividend level, three additional factors are required to calculate the fair value at which the S&P 500 should be trading at. These are, 1. The forecast average annual growth rate in earnings and dividends over the next ten years. 2. The forecast P/E ratio at which the S&P index will be trading in ten years time. 3. The estimated rate of return required by investors.

The S&P 500 portfolio average earnings should (in the longer term) grow at a rate close to the growth rate of the U.S. economy in nominal (after inflation) terms. I believe a prudent estimate for this nominal growth rate is 3% to 5% and I would focus on 4%. This 3 to 5% nominal GDP could occur with real GDP growth of 2 to 3% and inflation of 1 to 2%. We have a short article that both explains why (quoting Warren Buffett) and also demonstrates that historically earnings have tended to grow at about the same rate as nominal GDP growth in the long run.

The following graph illustrates that S&P 500 earnings have trended up at about the same rate as GDP growth (although slightly lower) over the long-term, although certainly with substantial volatility around the trend in individual years and over short periods of years.

This graph also clearly illustrates that the U.S. GDP (In nominal dollars, not inflation adjusted dollars)  has trended up steadily and has never failed to grow over say a three year period, except in the case of the 1930’s depression. This graph also shows a flattening in nominal GDP growth in more recent decades.

Note that we use a logarithmic scale on this chart. Logarithmic scales should always be used, on data that grows over time, when the time period is more than about 30 years because otherwise the lines will rise up exponentially. A constant percentage historic growth rate plots as a straight line on a logarithmic chart. Note also that the left and right scales are consistent in that each rises exactly 10,000 fold from bottom to top and each point on the right GDP scale is exactly 100 times higher than the corresponding point on the left S&P earnings scale. Many analysts improperly present data with inconsistent scales.

The next chart presents the same data but starting in 1987 and using a regular arithmetic scale so that we can more closely examine the graph over more recent years.

The S&P 500 earnings (the red line) plunged in 2007 and 2008 after reaching a peak in 2006. This graph shows that there is volatility in the relationship of S&P earnings to GDP. Importantly, it cannot be concluded on the basis of this graph that the 2017 earnings level was below the historic trend line. The trailing GAAP earnings value of \$109.88 noted above appears consistent with, or even somewhat above, the S&P 500 earnings trend since 1992 and on that basis it appears that \$109.88 represents something close to a normalized level of earnings as of 2017. Still, we adjusted that up to \$121 as an estimate of the impact of the income tax reductions effective for 2018.

The GDP figure is showing a small dip in 2009 with a full recovery by 2010 and continued growth through 2017.  Note that the GDP figures here are in nominal dollars, whereas reports of GDP growth percentages almost always refer to real, inflation-adjusted dollars.

Having determined and discussed the earnings level on the S&P 500 index we also need to make an assumption about the P/E level that is likely to apply to the index in the longer term.

The average for the S&P 500 P/E ratio since 1949 is 17.0 (this eliminates from the average any P/E greater than 50 which only occurred in 2008 when the earnings plunged to abnormally low levels). The average (on the same basis) since 1987 has been about 22. The Justifiable P/E changes with earnings expectations and the market’s required return on equities.

The linked article states “I have conservatively calculated that the current Justifiable P/E is about 14.3 assuming that with today’s low interest rates investors require about a 7% expected return and assuming that competition will drive available returns down to the required 7% level.” The article also indicates that if companies can deliver in perpetuity an 8% ROE when investors only require 7% (perhaps due to a lack of corporate competition) then a P/E of 21.4 can be justified but we considered that to violate equilibrium conditions.   However, it does appear that companies have been able to earn ROEs higher than the required return and to do so consistently which does justify a higher P/E.  The long-run P/E range used in our table below is 15 to 19. I have focused on a P/E level of 17, the long run average. Given today’s low interest rates 17 may be conservative. An argument could be made to assume a higher P/E such as 19.

I would estimate that a minimum (pre-tax) expected return required by stock investors (given today’s historically low interest rates) is in the range of 6% to 7%. The higher return required by investors then the lower the price or level that investors should be willing to pay for the index today, all else being equal.

The following table calculates the value that the S&P 500  will be  at in ten years given various forecasts for the earnings growth and given various scenarios for the forecast P/E ratio that will apply at that time. The second last column of the table then shows the fair or present value that we should be willing to pay today for the cash flows that would result from ten years of dividends plus the assumed cash from selling the index in ten years time. The present value is calculated based on various scenarios for the required return or discount rate.

The last column in the table indicates the average annual return that would be made if the S&P 500 is purchased at its recent level of 2588 and if earnings and dividends grow at the indicated rate and the index trades at the indicated P/E ratio in ten years time.

Conclusions

Given the current trailing-year earnings level of \$121 (adjusted up from the actual \$109.88 to account for lower income taxes going forward) and the current dividend of \$51.50, a range of expected earnings growth rates, the return required by investors and the assumed P/E ratio that will apply in ten years I can calculate that today’s S&P 500 index should be anywhere from 1660 (assumes that our starting adjusted earnings level of \$121 is reflective of a normalized starting point, that the market P/E falls to 15, earnings grow at only 4% annually and equity investors require an expectation of making 7%) to 2,580 (assumes our starting adjusted trailing year earnings level of \$121 was not an abnormally low or high earnings year, a terminal market P/E of 19 will apply in ten years, earnings will grow at 5% per year and investors only require an expectation of earning 6% on equities).

My own fair-value point estimate is 2078. This assumes that equity investors require a minimum 6.5% expected return, that the S&P earnings and dividend will grow at 4% (2% GDP growth plus 2.0% inflation) and that the long run S&P 500 P/E ratio is 17. This is the average of the two bolded and high-lighted rows in the table. Higher S&P 500  index values are implicitly assuming that the current normalized starting earnings level is higher than \$121, that earnings growth will exceed 4% annually, that the justifiable long-run P/E exceeds 17, and/or that investors require less than a 6.5% (pre-tax) return.

My range of investor required expected returns of 6% to 7%, although low by historic standards, is very attractive indeed compared to the recent 10-year U.S. government bond yield of about 2.8%. It also represents an attractive real return of 4% to 5% after an expected 2% inflation.

The last column in the table shows that under the indicated assumptions, if money is invested today in the S&P 500 and held for ten years and if the earnings and dividends grow at the rate indicated and the P/E ratio in ten years is as indicated then the average returns per year would range from 1.8% to 6.0% per year. With the 10-year treasury bond currently yielding about 2.8% a few of these estimated returns are perhaps attractive. Of course the earnings growth on the S&P 500 could be even lower than an average 3% per year and the terminal P/E ratio could be lower than 15, in which cases a lower return would result. It’s also possible that the P/E ratio will remain above 20 and/or that earnings will grow faster than 5% per year.

One can always come up with losing scenarios, or winning scenarios but based on historical earnings growth and P/E ratios it would appear that over this next ten year holding period, stocks are not that likely to provide very attractive returns (unless returns under about 6% are going to turn out to have been attractive, which is possible if inflation remains low).

The overall conclusion is that a fair value of the S&P 500 index based on its  trailing GAAP earnings adjusted upwards somewhat for the lower income taxes is probably about 2078. Since this is based on many estimated numbers it should be taken as a rough indication and certainly not as an exact determination.

My estimate in the two high-lighted rows is that the S&P 500 in ten years (the year 2028) will be at about 3045 (assumes 4% annual earnings growth from \$121 and a final P/E ratio of 17). Buying the S&P 500 index when it is at about 2588 (the level when this article was written) should be expected (but certainly not guaranteed) to result in a forecast return of about 3.9% per year if held for the next 10 years.  The expected standard deviation around this expected 3.9% is also large so that the actual return over the next 10 years might be expected to fall within a range of about 1% to 7% per year with some chance of being outside that range. And that return includes dividends and is before trading costs and personal taxes. And in any given year, the return will range wildly and should most definitely be expected to be negative in some years.

It is impossible to predict where the S&P 500 index will go in the next year. But it is possible to estimate its fair value and therefore whether or not it is currently over-valued based on reasonable growth expectations and a reasonable expectation around the initial earnings (or equivalently the  initial P/E level) and around the terminal P/E ratio. Caution is warranted because the S&P 500 can sometimes spend years in an over-valued or an under-valued-state. But ultimately, as we have seen in the early 2000’s crash, and the crash of 2008 and early 2009, valuation does correct itself.  (And sometimes over-corrects to the downside).

You can easily invest in the S&P 500 index by buying the ishares S&P 500 index Exchange Traded Fund under symbol IVV on the New York Stock Exchange. And if you are really bullish you can buy the double bull Proshares Ultra S&P 500 symbol SSO. Or if you are bearish there is the single bear ETF, Proshares short S&P 500 symbol SH, or the double bear Proshares Ultrashort S&P 500 symbol SDS. Be cautious and understand what you are buying.

Past Results from this Analysis.

Before placing any weight on the analysis above, you may be interested to review a summary of the fair values that we calculated in the past and whether or not our long-term analysis provided any hint of the 2008 market crash (Arguably the June 1, 2008 analysis provided some hint, especially for investors that felt that a 9% return was required for which we indicated a fair value of the S&P 500 index was 982 in that case and the index was sitting at 1400).

Keep in mind that with the past analysis we also provided a range of valuations and readers were free to select a different fair valuation from our table above.

The table below shows that our analysis appears to have been too conservative much of the time.  The ONLY time our analysis saw the S&P 500 as undervalued in the past eight years was near its major low in the Spring of 2009. And indeed, based on today’s S&P 500 level that was a time where an investor buying the S&P 500 has made an abnormally high return.

In general, based on where the S&P 500 is today, this past analysis now looks like it has been too cautious. It usually found the market to be over-valued when in fact investing at the dates indicated until today has provided a decent return in almost all  cases. Investing and holding at the dates shown from 2004 through 2007 provided, over the following ten years acceptable but unspectacular returns. Investing and holding in 2009 has, as of now, provided exceptionally good returns. (This is due, in large part, to the S&P 500 currently having a high P/E of 23.6 times trailing GAAP earnings  which is considerably higher than expected when we did the past analysis.)

This analysis attempts to look forward ten years. That’s always difficult to do and subject to much error. More than ten years have passed since our September 2004 analysis. At that time we were projecting that the S&P 500 index in September 2014 would be at 1,537 based on a P/E of 16 and that its earnings would grow 5% per year from \$59 to \$96 and that the dividend would grow from \$20 to \$33. The projection was intended to be reasonably conservative. The index ended September 2014 at 1,972 which was 28% higher than our projection. The earnings at about \$100 turned out be reasonably close while the dividend was then running about 21% higher than predicted. The P/E ratio at 19.5 was 22% higher than our base projection of 16 and higher than the top end of our projection which was a P/E of 18. If the P/E was at the long-term average of about 16 then our S&P 500 projection would have been quite close.
