In JP Morgan's Quarterly Market Guide a pair of charts on page 31 caught my eye.
Forward PE Estimates

I don't have any faith in forward PE estimates. They tend to be overly optimist and subject to numerous "one-time" writeoffs.
Instead, I recommend watching 10-year smoothed PE ratios. See discussion below.
Nonetheless, please note that even on a forward-basis, the S&P 500 ratio is well above most other markets.
Price to Book Valuations
On a price-to-book basis, US equities are twice as expensive as numerous other markets.
Case-Shiller Smoothed PE
The Case-Shiller PE is a Cyclically Adjusted Price-to-Earnings ratio, commonly known as CAPE, Shiller P/E, or P/E 10 ratio.
To calculate "CAPE", you divide the current price by the inflation-adjusted average of the last ten years of earnings.
Here is a link to the Current Shiller PE, updated daily. A better-looking chart is shown below.
Bubble Debate Revisited
Doug Short at Advisor Perspectives does periodic updates to the Shiller PE. His latest was on October 1 in Is the Stock Market Cheap?
On a PE/10 basis stocks are in the fifth quintile range signalling extreme overvaluation. Higher smoothed PEs happened in 1929, the dot-com bubble, 1902, and earlier this year.
The historic P/E10 average is 16.6. After dropping to 13.3 in March 2009, the ratio rebounded to an interim high of 23.5 in February of 2011 and then hovered in the 20-to-21 range. It began rising again in late 2013 and hit a new interim high of 27 in February of this year. It has now dropped below that high.For further discussion on just how over-valued US equities are, please see Bubble Debate; Equity Allocations vs. Shiller PE; Simple World.
Of course, the historic P/E10 has never flat-lined on the average. On the contrary, over the long haul it swings dramatically between the over- and under-valued ranges. If we look at the major peaks and troughs in the P/E10, we see that the high during the Tech Bubble was the all-time high above 44 in December 1999. The 1929 high of 32.6 comes in at a distant second. The secular bottoms in 1921, 1932, 1942 and 1982 saw P/E10 ratios in the single digits.
