NEW YORK (TheStreet) -- You always seem to hear people talking about what the "smart money" is buying. After all, if you can get into the same picks as Wall Street icons Warren Buffett and Carl Icahn, you have a better chance of cashing in, right?
That's not always true. A look back at some of the publicly traded stocks linked to the biggest investors and entrepreneurs on Wall Street shows a number of miscues in 2010. While these stocks aren't perfect benchmarks of one icon's investing success or failure, they give an indication as to whether it was a good year or a bad year.
Here's how six of Wall Street's biggest names fared in the past year:
Buffett Beats the Street 3x Over
Folksy investing icon Warren Buffett had another great year, at least by the measure of his renowned
stock. The Omaha holding company has racked up 20% returns year-to-date -- well over three times the
index's gains in 2010.
It's no surprise the value investor did well this year, since many good companies were depressed to bargain valuations after the volatility of 2009. And if you're wondering what value plays Buffett has in his sights for 2011, a look at the latest changes in
Berkshire holdings shows a concentration on financials and bank stocks.

Carlos Slim Sees Fat Profits
Mexican business tycoon
as the world's richest person in 2010, according to
, and it's no surprise why. As the CEO of Latin American telecom giants
( TMX) and
, he has shared in the success of emerging markets big time.
While Telmex has seen some earnings trouble recently and is lagging with 8% loss year-to-date, America Movil has soared 20% so far in 2010. That's over three times the broader stock market. What's more, Carlos Slim's global conglomerate
(GPOVY) has exploded late in the year -- racking up 70% returns in 2010 and over 55% returns since Aug. 1 alone!
Jobs Rides Apple and Disney to Big Gains
Apple's rock star CEO Steve Jobs is best known for his magic product launches and habit of micromanaging product development. But he is also a Wall Street heavyweight. As of the end of 2009, Jobs owned nearly 5.5 million shares of
as well as 7% stake in
-- about 138 million shares, which he received in exchange for Disney's acquisition of Pixar in 2006.
Both stocks have paid off. Disney gained 15% in 2010, more than double the S&P's performance. Apple lapped the market seven times over due to another successful iPhone launch and the breakout success of the iPad tablet computer.

Icahn Enterprises Suffers in 2010
Carl Icahn has been making some headlines in 2010, most recently with his moves to buy
Lions Gate Entertainment
and to unload his stake in
. Yet judging by the performance of publicly traded
, Carl's moves have been largely unwise in 2010 -- the holding company is off about 12% on the year compared with 6% returns for the S&P 500 so far in 2010. IPE is also off about 75% from its early 2008 peak.
Microsoft Loss Won't Break Gates' Bank
Though his brainchild
is now run by Steve Ballmer, billionaire Bill Gates still has a lot riding on the company. Gates remains the largest individual shareholder with more than 8% of the common stock. That means 2010 took a big chunk out of the tech icon's pocketbook, with Microsoft sliding more than 15% on the year.
The company did boost its dividend to a yield of about 2.5%, but that still doesn't make up for the loss. In case you're worried about Mr. Gates' finances, don't be. Though
Gates was bumped from ranking as the "world's richest person" by Carlos Slim, being the second-wealthiest fellow on the planet isn't all that bad either. With $53 billion in net worth, Gates is not headed for the poorhouse.
Oracle Pays Off for Ellison
Larry Ellison, cofounder and chief executive officer of
, is another Silicon Valley icon who has become a Wall Street fixture. As of Nov. 15, he owned a whopping 1.1 billion shares of Oracle -- yes, that's billion with a B -- for roughly 20% of the company.
That cache of stock appreciated nicely in 2010, rising 15% while the broader stock market added only half as much. Part of the reason for the bounce is likely a broader tech recovery, but the acquisition of Java software giant
early in the year has probably also put some spring in Oracle's step. And, of course, cash in Ellison's bank account.
