KiOR Inc (KIOR), Kraton Performance Polymers Inc (KRA), Protalix BioTherapeutics Inc. (PLX): 4 Longshot Stocks to Invest In

RPX Corp (NASDAQ:RPXC)

^SPX data by YCharts

RPX Corp has cruised 67% in the past six months. The company acquires large swaths of intellectual property that could become problematic in an industry and provides patent access to its clients on a subscription basis. Some call it patent trolling, some call it consolidation that reduces patent litigation. Either way, there is a unique compounding affect to the company’s growth. The more IP it acquires, the more useful its services, and the more powerful it becomes.

The company hit the markets in 2011 at an over-hyped IPO price in the high $20s, briefly topped $30 per share, then fell to $8.55 per share in late 2012. RPX Corp (NASDAQ:RPXC) has recovered nicely since and sits at a valuation of just $750 million with soaring top and bottom lines. Whether or not the business model catches fire is up for debate. But with 146 customers on the books now, the future looks bright.

Foolish bottom line
These are just four companies that have eye-popping potential with a healthy dose of risk and what-ifs. Nonetheless, investors that get in at reasonable prices today could capture big returns from these black sheep if they prove their business models in the years to come. I would like to see more results from KiOR Inc (NASDAQ:KIOR) and more stable growth from Kraton. Meanwhile, Protalix BioTherapeutics Inc. (NYSEAMEX:PLX) has interesting IP in its ProCellEx platform that could be eyed by a number of pharmaceutical companies. At the end of the day however, my favorite is RPX for its clean balance sheet, growing revenue, and strong-armed business model. Do you know of another longshot stock to invest in?
