Here is a summary of the four market valuation indicators I updated at the beginning of the month.
- The Crestmont Research P/E Ratio (more)
- The cyclical P/E ratio using the trailing 10-year earnings as the divisor (more)
- The Q Ratio, which is the total price of the market divided by its replacement cost (more)
- The relationship of the S&P Composite to a regression trendline (more)
To facilitate comparisons, I’ve adjusted the two P/E ratios and Q Ratio to their arithmetic means and the inflation-adjusted S&P Composite to its exponential regression. Thus the percentages on the vertical axis show the over/undervaluation as a per cent above mean value, which I’m using as a surrogate for fair value. Based on the latest S&P 500 monthly data, the market is overvalued somewhere in the range of 34% to 50%, depending on the indicator. This is an increase from the previous month’s 33% to 46% range.
I’ve plotted the S&P regression data as an area chart type rather than a line to make the comparisons a bit easier to read. It also reinforces the difference between the line charts — which are simple ratios — and the regression series, which measures the distance from an exponential regression on a log chart.

But they can play a role in framing longer-term expectations of investment returns. At present they continue to suggest a cautious long-term outlook and guarded expectations.
