Most of us would be thrilled to invest in a stock that doubles our money, but it certainly isn't easy to find these stocks. According to data provider Capital IQ, in the last year only 1.4% of 6,700 stocks trading on the U.S. exchanges were able to double their price.

BusinessWeek started hunting some of these potentially great stocks by asking fund managers to choose those firms expected to provide 100% returns in the next few years. Of course, the resulting list is by no means a sure thing, since major factors such as the ongoing credit crisis and challenging market conditions could affect results in unpredictable ways.

But let's look at some of the strategies used when picking high-potential stocks.

Mary Lisanti, portfolio manager at the Adams Harkness Small Cap Growth Fund, focuses on young companies in the small-cap segment. She points to stocks like Rubicon Technology (NASDAQ: RBCN) and Titan Machinery Inc. (NASDAQ: TITN), saying that investors can have a big advantage when they recognize potential before the market does.

Last week Forbes released its annual list of the fastest growing tech stocks, and it shouldn't be much of a surprise that Google Inc. (NASDAQ: GOOG) topped the list, with nearly $15 billion in sales, representing five-year sales growth of 155%, and 30% EPS growth. To make the list, companies had to have significant sales growth over the past year and five years, as well as a good earnings forecast for the next three to five years. Companies with significant legal problems or corporate governance issues were excluded.

Rounding out the top five were Salesforce.com (NYSE: CRM), Ceradyne Inc. (NASDAQ: CRDN), Euronet Worldwide Inc. (NASDAQ: EEFT), and FalconStor Software Inc. (NASDAQ: FALC). Some other familiar names that made the list this year include Red Hat Inc. (NYSE: RHT), L-3 Communications (NYSE: LLL), Adobe Systems Inc. (NASDAQ: ADBE), and Cognizant Technology Solutions (NASDAQ: CTSH). Cognizant has been on Forbes list since its inauguration six years ago. For the full list, see the Forbes article.

Also of interest was the Forbes Fast 15, companies that didn't make the list mentioned above, but which Forbes thought were worth keeping an eye on for their potential. Engineering software maker Ansys Inc. (NASDAQ: ANSS), semiconductor maker Atheros Communications Inc. (NASDAQ: ATHR), Brubaker BioSciences Corp. (NASDAQ: BRKR), and scoreboard maker Daktronics Inc. (NASDAQ: DAKT) top that list. For the full list, see the Forbes article.

So if, like Aaron Katsman, Georges Yared, and Jim Cramer, you are bullish on tech stocks, then there's plenty on the Forbes lists worth taking a look at.
