This week’s Barron’s interview featured Jason Trennert of Strategas Partners. Jason is bullish about the U.S. market and bearish about emerging markets. Much of his logic is sound, and his conclusion is fine–the U.S. market goes up about two-thirds of the time, so predicting it will go up this year is rarely a dumb bet. One of Jason’s points is flawed, however:
We expect $93 for S&P 500 operating earnings in ’07, and that puts the market at roughly 15 times earnings…The downside risk is low because P/Es are so low.
P/Es are not "so low." In fact, they’re not even "low." To get to "15-times earnings", Jason is looking at "forward operating earnings" (an estimate). He’s then comparing it to last-twelve-months earnings. Cliff Asness has written in detail about the folly of this apples-to-oranges comparison. According to Cliff, the average "forward operating earnings" P/E is 11-times, not the 15-times that Jason and other contemporary bulls throw around. This 11-times, moreover, is an average–so half the time the market’s P/E has been below this level.
The market may go up, but, if so, it won’t be because P/Es are low.
