Titan Machinery (NASDAQ: TITN) owns and operates one of the largest networks of full service agricultural and construction equipment stores in North America. The chain includes 48 dealerships in North Dakota, South Dakota, Minnesota, Iowa and Nebraska, each representing one or more of the CNH Global (NYSE: CNH) equipment brands. The firm sells new equipment, rents a range of machines and provides parts and repair services. Deere & Company (NYSE: DE) is a major competitor.

The company pleased investors earlier in the week, when it reported fiscal Q1 EPS of 24 cents and revenues of $152.6 million. Analysts had been looking for 13 cents and $119.6 million. Management also guided FY09 EPS to 86-91 cents (79 cent consensus) and FY09 revenues to $575-$625 million ($588.55M consensus). The CEO cited a strong agriculture economy and solid demand for large agricultural equipment in support of the favorable outlook.

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.

All it takes is some news to make you realize the risk involved in smallcap investing. That news came in the form of a horrific earnings report last night from Origin Agritech (NASDAQ: SEED), showing revenues and margins decreasing along with guidance that was more than 50% below the estimates of the one analyst that covers the company.

I often advise against trusting any company whatsoever, but it's rare that one lets investors down so greatly. I had no position in the stock, but along with Converted Organics (NASDAQ: COIN) and Titan Machinery (NASDAQ: TITN), I profiled Origin back in January as an up and coming agriculture stock. Since then, two of those three stocks have broken out to new highs in a similar fashion to this hot sector's leaders like Potash Corp. of Saskatchewan (NYSE: POT), Mosaic (NYSE: MOS), Monsanto (NYSE: MON) and Agrium Inc. (NYSE: AGU).

Performance aside, those billion dollar behemoths are established companies, with global investors and brands, while these new kids on the block are the exact opposite. Plagued by having few products, fund raising problems and debt issues, this 50% shortfall exemplifies just one of the many issues with which small-cap companies struggle. I mean they are really fighting for lives! And that's why they are priced the way they are and derided by Wall Street.
