S&P 500 P/E Ratio
Friday, May 17, 2013 at 09:23AM The S&P 500's P/E ratio has been seeing some pretty rapid expansion this year as the market has charged higher. As shown below, last year at this time, the S&P's trailing 12-month P/E ratio was below 14. Now it's up to 16.13.

While the one-year P/E ratio chart above looks pretty alarming, a longer term chart looks much less so. Below is a chart of the S&P 500's trailing 12-month P/E ratio over the last 15 years. In the chart, we have pointed out where the P/E ratio stood when the S&P hit its highs back in 2000 and 2007. As shown, at the March 2000 bull market peak, the S&P's P/E ratio was all the way up at 30.97. At the market's peak in 2007, the P/E ratio was at 17.52. Over the last 15 years, the average P/E ratio for the S&P 500 has been 19.58, so at 16.13, the index's valuation is currently 17.62% below its 15-year average.
