Q: It is my understanding that the P/E ratio of the S&P 500 is hovering around 28. In the last 135 years, it had only been higher 4% of the time; once in 1929 and once just before the tech crash of 2000/2001. Do you think the future of U.S. stocks is a little obvious?

A: There are many different ways to value stocks, ranging from the discounted cash flow (DCF) method to the price to earnings (P/E) ratio. The P/E ratio is probably the most common metric used by investors today.
The two primary types of P/E ratios are trailing 12-month price to earnings and forward 12-month price to earnings. Trailing P/E ratios are calculated by dividing the price of a stock by the actual reported earnings of a company for the past 12 months. This is the ratio you are referring to, Rod. Forward 12-month price to earnings are based on an estimate of earnings for the coming 12 months.
Estimated earnings are not as reliable as actual earnings. But actual financial results of a company or a stock market over the past 12 months may not necessarily be a predictor of potential earnings for the coming year. Since stock prices are based on expectations for the future, one could argue that forward P/E ratios are more important.

If a stock price is high and earnings are low, it will have a high P/E ratio and therefore may be overvalued. Think technology stocks in the dot-com bubble with no earnings. If a stock has a low P/E, the stock price may represent a good value. Value investors like Warren Buffet look for undervalued stocks.
Right now, the trailing 12-month P/E ratio for the S&P 500 is 24.68. Historically, this ratio has averaged 15.64 since 1871, so we are definitely above average, Rod and in the “red zone” so to speak.
That said, the forward 12-month ratio is currently 18.27 according to Birinyi Associates and the Wall Street Journal. This suggests that despite U.S. stocks sitting at all-time highs and trailing P/E’s in the red zone, stock prices remain reasonable at least based on estimated earnings for the coming year and the resulting S&P 500 forward P/E ratio.
