Stimulus, schmimulus. Wall Street can't be fixed the way it is, President Obama. The system needs a total overhaul.

It's not just the bankers who are to blame. Sure, hundreds of them should be in jail -- they cost us billions by taking on more leverage than they could afford, and by betting on sure losers like credit default swaps on U.S. government bonds.

It was hubristic. Moronic. And directly linked to the economic conditions that argue for hundreds of billions in stimulus. Thanks for that, guys. Thanks a lot.

But here's the thing: Even if we jail the bankers, we're left with the analysts -- Harvard-trained number crunchers who treat stocks as if they were part of some sort of flavor-of-the-month club. They'll cheat you out of a fortune if you let them.

How to give away a fortune
You see, analysts abide by a specific vernacular that begins and ends in 12-month price targets. That's by design; big brokers serve big clients and big clients -- institutional investors such as mutual and hedge fund managers -- move money into and out of stocks as fast as a hyperactive 2-year-old on a sugar high. These traders need to know the flavor of the month, the day, the hour, the minute.

Some even profit from the process. Ken Heebner of the CGM Focus (CGMFX) fund, whose current holdings include Abbott Laboratories (NYSE:ABT) and Best Buy (NYSE:BBY), swaps out the contents of his entire portfolio at least three times annually. And yet he's still produced a full decade of 16.3% average annual returns, crushing the S&P.

So why not trade as Heebner does? Two reasons:

  1. There's only one Ken Heebner.
  2. You aren't him.

Actually, there's also a third reason. Heebner almost never gets his ideas from the Street. "I'm not waiting for Morgan Stanley to tell me there's something wrong in China," Heebner told Fortune in a May 2008 interview. "By then it's too late."

Heebner, in other words, is proof of the folly of following the Street's upgrades and downgrades. Here's more: Green Mountain Coffee Roasters, one of the market's 10 best stocks of the past decade, has been downgraded to something less than "buy" eight times.

The first downgrade, by Adams Harkness on October 25, 2002, was from "buy" to "market perform." But of course, it didn't -- Green Mountain was built to outperform. From then until now, the stock has been a 16-bagger versus an 11% gain for the market-tracking S&P 500 SPDR.

Interestingly, Green Mountain earned roughly 43% of that gain between Oct. 25, 2002 and Oct. 24, 2003 -- the one-year period in which analysts operate. And how did the SPDR do? Up 16.7%, it turns out. That's two strikes, Adams Harkness.

But let's not pick on a single analyst. Or cherry-pick dates, for that matter. There's no reason to; the data shows that upgrades and downgrades don't matter nearly as much as the headlines suggest. Every one of these winners was downgraded to something less than "buy" at least once during its five-year run:

Following the Street's gyrations might have earned you profits in these stocks, but it might also have cost you fantastic returns. With the S&P down roughly 11% over the same period, you'd almost certainly have done better buying after the first downgrade and holding for as long as the underlying business supported your thesis for investing.

Stimulate your portfolio
If this process sounds familiar, it should. Fool co-founder David Gardner sustained a decade of 20% returns in the real-money Rule Breaker portfolio by zigging when the Street and major financial press screamed zag. His contrarian investing style echoes Heebner, who told Fortune that he's most comfortable as an investor "when everyone else thinks I'm nuts."

The beauty of David's rebellious style of investing is that you'll rarely be short of ideas; upgrades and downgrades occur daily. found 10 downgrades this morning, including J. Crew (NYSE:JCG) and First Solar (NASDAQ:FSLR).

My favorite idea right now is a current pick of David's for Motley Fool Rule Breakers that, in January, was downgraded three times. Crazy. Not only is this business the undisputed leader in an emerging sector of the health care market but the stock has also more than doubled since David first picked it for the April 2005 issue. Yet analysts say now -- right as this well-heeled cash gusher is trading well off its 52-week high -- is the time to sell. Color me thrilled.
