Just released from Jeremy Grantham, who has gone, for all intents and purposes, "balls to wall" bearish.
"I do not feel the same degree of confidence that I did, which was considerable, that the Fed could carry all before it until October 1 of this year. A third round of quantitative easing would very probably keep the speculative game going. But without a QE3, there seem to be too many unexpected (indeed unexpectable) special factors weighing against risk-taking in these overpriced times. I had recommended taking a little more risk than was justified by value alone in honor of Year 3, QE2, and the Fed in general. Risk now should be more reflective of an investment world that has stocks selling at 40% over fair value (about 920 on the S&P 500) and fixed income, manipulated by the Fed, also badly overpriced. Although the taking of some “extra” risk by riding the Fed’s coattails has been profitable for six months, I admit to being a bit disappointed: I really felt the market had the Fed’s wind in its sails and would move up deep into the 1400 to 1600 range by October 1, where it would be, once again, over a 2-sigma 1-in-44-year event, or, officially, a bubble. (At least in a world where GMO is the official.) At such a level, I was ready to be a real hero and absolutely batten down the hatches, become extremely conservative, and be prepared to tough out any further market advance (which, with my record, would be highly likely!). The market may still get to, say, 1500 before October, but I doubt it, especially without a QE3, although the chance of going up a little more by October 1 is probably still better than even. And whether it will reach 1500 or not, the environment has simply become too risky to justify prudent investors hanging around, hoping to get lucky. So now is not the time to float along with the Fed, but to fight it. Investors should take a hard-nosed value approach, which at GMO means having substantial cash reserves around a base of high quality blue chips and emerging market equities, both of which have semi-respectable real imputed returns of over 4% real on our 7-year forecast. The GMO position has also taken a few more percentage points of equity risk off the table."
