Since early 2007, it's been rough for the shareholders of Cowen Group Inc (NASDAQ: COWN), a mid-tier investment bank. The company's stock price has gone from $20 to low of $3.54.But lately, Cowen's stock price has perked up, primarily because of takeover overtures. For example, there was an offer from Rodman & Renshaw at $7 per share.
However, this was rebuffed. Instead, yesterday Cowen agreed to a so-called "reverse merger" with hedge fund Ramius LLC, which will own 71% of the new entity. On the news, Cowen's shares increased 37%.
