The following commentary comes from an independent investor or market observer as part of TheStreet's guest contributor program, which is separate from the company's news coverage.By Dave Sterman NEW YORK ( StreetAuthority) -- I spend much of my time in search of companies that possess robust growth prospects. But I'm also content to occasionally focus my energy on companies that are unlikely to grow meaningfully. The catch: these companies must be able to generate a huge amount of profit from their sales base in a consistent manner. Or they need to own a set of assets that would be highly coveted by other firms in an industry. I think I've found a company that checks off both of those boxes. New York-based Cablevision ( CVC) generates stunning amounts of free cash flow. And recent events make me think the company may soon receive a very flattering offer from a rival or a private-equity (PE) firm.
