GRANTHAM: The stock market sell-off makes me nervous, but I fear the big crash is coming later

Jeremy Grantham is surprisingly bullish!

In his latest quarterly outlook, Grantham, cofounder and chief investment officer at GMO, outlines his views on the markets and the economy.

And in somewhat of a contrast to his recent commentary, sees the oil crash as a big tailwind for the economy and doesn't think the stock market, though it is expensive and potentially heading into a bear market, is going to crash.

"Looking to 2016, we can agree that uncertainties are above average," Grantham writes.

"But I think the global economy and the U.S. in particular will do better than the bears believe it will because they appear to underestimate the slow-burning but huge positive of much-reduced resource prices in the U.S. and the availability of capacity both in labor and machinery."

Grantham adds (emphasis ours):

As always, though, prudent investors should ignore historical niceties like these and invest according to GMO’s rather depressing 7-year forecast. The U.S. equity market, although not in bubble territory, is very overpriced (+50% to 60%) and the outlook for fixed income is dismal.

At current asset prices no pension fund requirements can be met. Thus, we should welcome a major market break that will leave us with more reasonable investment growth potential for the longer term, but I suspect that we will have to wait patiently for such a major decline.

The ability of the market to hurt eager bears some more is probably not exhausted. I still believe that, with the help of the Fed and its allies, the U.S. market will rally once again to become a fully-fledged bubble before it breaks. That is, after all, the logical outcome of a Fed policy that stimulates and overestimates some more until, finally, some strut in the complicated economic structure snaps. Good luck in 2016.

OK, so maybe not bullish, per se, but Grantham is definitely sounding the alarm on not sounding the alarm on a stock market bubble and resulting crash.

Stocks

Over the last 18 months, stocks are basically flat in what has been by far the most difficult period for investors since the financial crisis.

And this period has really been defined by three things: a crash in oil prices, a continued and relentless slowing of the Chinese economy, and a change in Federal Reserve policy.

On top of all this is the decline in profit margins, which Grantham has called the "most mean-reverting series in finance," implying that the long period of elevated margins we've seen from American corporations is most certainly going to come an end. And soon.
