Contributing to the case for a healthy pullback in September is the view shares are quite overvalued.  We found some great stuff over the weekend from seeitmarket.com.  The lede:

“Valuations are still well below the peak of 1999” say the bulls.

They are certainly correct from an absolute basis but we caution that the current level of stock market euphoria is in a league of its own when compared to prior peaks on an “apples to apples” basis.

The following table compares earnings growth and implied market expectations for earnings growth from the two prior CAPE (Cyclically-Adjusted Price-to-Earnings) peaks to today.

CAPE is the price of an equity index, such as the S&P 500 Index (INDEXSP:.INX) in this case, divided by the average of ten years of earnings adjusted for inflation.

Implied market earnings growth is the rate of earnings growth required for the next ten years to return CAPE to its historical average assuming no price changes.

More:  When one compares current valuations and supporting economic fundamentals to data that preceded damaging market corrections, they may conclude, like us, that today’s equity market valuations may very well be the most egregious observed.

Like any illness, one cannot begin to treat a condition until it is properly identified. 720Global and many other astute market observers continue to produce compelling evidence that there are a variety of economic ills and gross mis-valuations with which investors must contend. The absence of consequences to this point seems to be broadly misinterpreted as “all’s well”. It is the medical equivalent of “the x-ray must be wrong because I feel fine.” The evidence argues otherwise just as it did in the months preceding 2000 and 2008.
