US CAPE and q chart

US CAPE and q chart.

With the publication of the Flow of Funds data up to 31st March, 2014 (on 6th June, 2014) we have updated our calculations for q and CAPE.

Both q and CAPE include data for the year ending 31st March, 2014. At that date the S&P 500 was at 1872 and US non-financials were overvalued by 81% according to q and quoted shares, including financials, were overvalued by 79% according to CAPE. (It should be noted that we use geometric rather than arithmetic means in our calculations.)

As at 6th June, 2014 with the S&P 500 at 1949 the overvaluation by the relevant measures was 88% for non-financials and 87% for quoted shares.

Although the overvaluation of the stock market is well short of the extremes reached at the year ends of 1929 and 1999, the chart shows that it has reached the other previous peaks of 1906, 1936 and 1968.

Data for our calculations of q are taken for 1900 to 1952 from Measures of Stock Market Value and Returns for the Non-financial Corporate Sector 1900 – 2002 by Stephen Wright, published in the Review of Income and Wealth (2004) and for 1952 to 2014 from the Flow of Funds Accounts of the United States (“Z1”) published by the Federal Reserve. Data for our calculations of CAPE are taken from the data published on Robert Shiller’s website, updated from data published by Standard & Poor’s and the BLS.
