The Value of Fundie Analysts?

Tuesday, March 06, 2007 | 07:00 AM

Since we brought up the brewing I/B/E/S Analyst ratings scandal Monday, we thought this an opportune time to revisit some interesting observations of Rich Bernstein via Barron's Alan Abelson.

Yesterday, we discussed that some analysts at major firms have been "tweaking" and "correcting" their prior ratings and up/downgrade history. This was done apparently to improve their historical track records. Of course, not everyone did this; the professors who authored the study found "only" 54,729 non-random, ex-post changes out of 280,463 (19.5%). Based on those numbers, we can presume many of the analysts who participate in the I/B/E/S rating system are ethical -- or at least were unwilling to game the system or make changes to ratings after the fact.

A quant study from Merrill's Bernstein -- released prior to this news breaking -- takes a different, contrary to the crowd tack. It turns out that the stocks in the S&P 500 with the least analyst coverage outperformed the rest in 2006 -- and quite handily, also:

"BEFORE 2006 SLIPS AWAY FURTHER into the mists of history, we might pass along some conclusions about that surprising, rewarding and rambunctious year we found especially interesting. They're from the pen of Rich Bernstein, Merrill Lynch's chief investment strategist, who, despite that ominous title, is a sensible and knowing observer of the stock market.

More specifically, Rich addressed the question of what were the best performing investment strategies in '06 among the 40 or so tallied by the firm's quants, rather a logical subject for a leading brokerage house's No. 1 strategist. Why do we find it more than a little deliciously ironic that he discovered that the very best strategy was buying stocks with scant analyst coverage? Maybe it had something to do with the fact that, at last count, Merrill employed no fewer than 750 analysts in its global research network.

In any case, Rich asserts that the investor who concentrated on the 50 stocks in the S&P 500 that are followed by the fewest Wall Streets analysts wound up with a rousing 24.6% gain in the 12 months ended Dec. 29. That handily beats the quite decent 13.6% advance of the S&P 500, or, for the matter, the 14.6% rise by the index when calculated on an equally weighted basis.

Which -- how could it not? -- brought to mind that wonderful piece of advice rendered years ago by that famous curmudgeon and demon investor Gerald Loeb as to what ordinary folks investing in equities ought to remember about security analysts: "In bull markets, you don't need 'em; in bear markets, you don't want 'em." (emphasis added)

Fascinating stuff. Other strategies that outperformed the S&P500's 13.6% gains: Stocks that had low price-to-cash-flow multiples (23%), and those with a high dividend yield (21.7%);

Weakest strategy? Growth did a little better than cash (5.7%) -- "despite the consensus at the beginning of the year that 'growth would outperform value in 2006, investors who stayed with value and out-of-favor stocks' racked up the best returns."

My question to Bernstein & Co. is this: How has this approach worked in the past? Is it only a 2006 phenomena, or has it been successful in years prior? 

So while we ponder what this brewing ethical quamire of analyst ratings means to the industry and to investor confidence, there may be another lesson embedded in this for stock pickers: Look for stocks off the beaten path, and away from the best known, best covered names.

Given the extreme goofiness of seeing analysts state the obvious (read, putting in outperform ratings on stocks that just blew out their numbers or the obverse, putting sell or hold ratings on stocks suffering "whackage"), I've never taken any of these analyst ratings into consideration. (And let's not forget the controversial analyst call for NEW being trumped about)unless it is to bet against them. The money moves in for buys and out for sells so quickly, for the quick it can be a profitable flip.
