I update market valuations on a monthly basis. I am using six metrics to conclude whether the market is overvalued or undervalued.

I collaborate with my colleague Doug Short for some of the data I use in the article. Doug is an expert on market valuations, and I encourage readers to visit his site dshort.com

As always, I must mention that just because the market is over or undervalued does not mean that future returns will be high or low. From the mid to late 1990s the market was extremely overvalued and equities kept increasing year after year. However, as I note at the end of the article I expect low returns over the next ten years based on current valuations.

To see my previous market valuation article from last month click here.

The content will be mostly the same. I will be mostly updating the numbers, and the commentary as to what level the market valuations are at. I will be adding more historical data as I find it.

Below are six different market valuation metrics as of July 2nd, 2010:

Current P/E TTM 17.2

The current P/E is 17.2 TTM, which is lower than the TTM P/E of 18.1 from last month. The P/E TTM is currently slightly overvalued.

This data comes from my colleague Doug Short of dshort.com.

Based on this data the market is moderately overvalued. However I do not think this is a fair way of valuing the market when considering the significant decrease in earnings over the past year. To get an accurate picture of whether the market is fair valued based on P/E ratio it is more accurate to take several years of earnings.

Current P/E 10 Year Average 18.3

The 10 year P/E ratio is currently 18.3. This is below the measurement from my previous article of 19.76. This number is based on Robert Shiller’s data evaluating the average inflation-adjusted earnings from the previous 10 years.

My colleague Doug Short thinks this numbers are a bit inaccurate, because the number I used does not include the past several months of earnings, nor revisions. Doug calculates P/E 10 at 19.9.

This is moderately over valued from the average P/E as shown above.

Current P/BV 1.9

This is a very rough estimate, it is nearly impossible to get an exact number for P/B on a specific date to my knowledge.

The current P/BV is 1.9 , this is below P/B of 2.1 I measured in my previous article.

The average Price over book value of the S&P over the past 30 years has been 2.41. This indicates the market is slightly undervalued valued. Book value is considered a better measure of valuation than earnings by many investors including legendary investor Martin Whitman. He states that book value is harder to fudge than earnings. In addition book value is less affected by economic cycles than one year earnings are. P/BV therefore provides a longer term accurate picture of a company’s value, than a TTM P/E.

Current Dividend Yield 2.13

The current dividend yield of the S&P is 2.13. This number is higher than the 2.01 yield from my previous article.

It is hard to determine on this basis whether the market is overpriced. The dividend yield for stocks was much higher in the begging of this century than the later half. The dividend yield on the S&P fell below the yield on Ten-Year treasuries for the first time in 1958. Many analysts at the time argued that the market was overpriced and the dividend yield should be higher than bond yields to compensate for stock market risk. For the next 50 years the dividend yield remained below the treasury yield and the market rallied significantly. In addition the dividend yield has been below 3% since the early 1990s. While I personally favor individual stocks with high dividend yields, I must admit that the current tax code makes it far favorable for companies to retain earnings than to pay out dividends. Finally, as I noted above the current economic environment has zero percent interest rates and low bond yields. During periods where yields are low it is logical for income oriented investors hungry for yield to be bid up the market, and dividend yields to decrease. I think it is hard to claim the market is overbought based on the low dividend yield.
