Investment Guru Predicted Crash

“There will always be someone predicting disaster and someone predicting great fortune. At one time or another, each will be closer to correct than the other. But it won’t matter to you if you understand this and have invested responsibly. You have a long-term plan; stick with it.” Peter Lynch.

In my previous post, one of the individuals quoted was Jeremy Grantham, a very successful money manager, who has been getting a great deal of media attention lately. He was among the “Fortune Tellers” featured in New York Magazine’s December 7th article, Oracles of Doom.

In addition, late last month, Grantham was the sole guest on PBS’s popular investment program, Consuelo Mack: WealthTrack. She described him as a modern-day “Cassandra,” noting that he predicted today’s depressed stock prices a decade ago.

I might be in the minority here but, in my opinion, being pessimistic 10 years in advance isn’t all that useful.

Now, don’t get me wrong, I think Grantham is very intelligent and quite eloquent. He’s also very convincing. The problem I have with him is that he has been bearish for so long, that eventually, he had to be right.

You can read more about his prophesies in Here Comes the Crash, an article published in the November 15, 2004 Fortune magazine.

Talk to Jeremy Grantham about the stock market, and you get the impression the sky is about to fall. For years the chairman and chief strategist of money-management firm Grantham Mayo Van Otterloo has been gleefully rattling listeners’ nerves with his claim that the excesses of the dot-com bubble still haven’t been unwound and that the market is headed for another precipitous drop. About a year ago his prediction became alarmingly specific. Shortly after this year’s election, he says, the market will sink into a “black hole,” losing about a third of its value over the next two to three years. He sounded this warning most publicly at the annual Morningstar investment conference in July. In late October, speaking from his elegant Boston townhouse, he told FORTUNE, “We’re still in the unraveling of the greatest bull market in American history.”

To be fair, from what was printed in the Fortune article, he has been right:

Using GMO’s computer models, he has made several well-timed calls. In 1982, with stocks selling at fire-sale prices and the economy recovering, he predicted the market was ripe for a “major rally.” That year the U.S. market kicked off its longest bull run ever. He also called the top of the Japanese bubble in 1989, the resurgence of U.S. large caps in 1991, and the rallies in U.S. small-cap and value stocks in 2000.

But, he has also been wrong:

He turned bearish on U.S. equities in the mid-1990s, prompting clients to shift money to other firms.

His prediction in 2004 was that “The low will come two or three years from now, at a level below 700 on the S&P.” That’s not what happened at all. In fact, the S& P 500 went up in 2003, 2004, 2005, 2006 and 2007. Finally, in 2008, his pessimism paid off.

A web site from CXO Advisory Group rates investment “gurus.” According to them:

Jeremy Grantham has been persistently very negative about the prospects for U.S. equities (apparently since 1994), but not for international equities.

Based on subsequent stock market performance and our judgments about his forecasts for overall stock market direction, Jeremy Grantham’s forecast accuracy rate is 48%, which is about average. His forecast sample size is very small, as is our confidence in this score.

Note that carefully: 48%. One could argue that an accuracy rate of 48% is not dissimilar from simply using a coin tossed in the air to determine your prediction.

Finally, if the stock market had gone up this year, I doubt that Jeremy Grantham would be getting this much favorable press.
