The S&P 500 Cyclically Adjusted PE (aka S&P 500 or Shiller PE10 or CAPE) – February 2013 Update

The US stock market has seen some large gains since New Year’s Eve. As I write this post the mid market price for the S&P500 is down 0.9% on the day at 1,499.8 but still up 5.2% in little over a month. Similarly, the Dow Jones is down 0.8% at 13,903.5 but is up 6.1% since the market close on the 31 December 2012. It’s therefore appropriate to run the standard Retirement Investing Today monthly update for the S&P500 Cyclically Adjusted PE (S&P 500 CAPE). Let’s see if the market is just exuberant or starting to head towards Irrational Exuberance.  Last month’s update can be found here.

As usual before we look at the CAPE let us first look at other key S&P 500 metrics:

• The S&P 500 Price is currently 1,500 which is a rise of 1.3% on last month’s average close of 1,480 and 13.3% above this time last year’s monthly Price of 1,324.
• The S&P 500 Dividend Yield is currently 2.1%.
• The S&P As Reported Earnings (using a combination of actual and estimated earnings) are currently $88.85 for an Earnings Yield of 5.9%.
• The S&P 500 P/E Ratio is currently 16.9 which is up from last month’s 16.8.

The first chart below provides a historic view of the Real (inflation adjusted) S&P 500 Price and the S&P 500 P/E.  The second chart below provides a historic view of the Real (after inflation) Earnings and Real (after inflation) Dividends for the S&P 500.

As always let us now turn our attention to the metric that this post is interested in which is the Shiller PE10.  This is also shown in the first chart which dates back to 1881 and is effectively an S&P 500 cyclically adjusted PE or CAPE for short.  This method is used and was made famous by Professor Robert Shiller.  It is simply the ratio of Real (ie after inflation) S&P 500 Monthly Prices to 10 Year Real (ie after inflation) Average Earnings.
