Rambus (RMBS: sentiment, chart, options) is down over 18 percent today on news that the European Patent Office revoked the patent for one of its semiconductors. Nevertheless, RMBS call options have out-traded put options today by a margin of more than three to two. Investors seem to be betting that the stock will rebound even amid the negative fundamental news and recent breakdown in the stock's technical picture. The Schaeffer put/call open interest ratio has been trending lower as the stock has continued to fall, which could signal a continuation to the downside for the shares. -JDS
Looks like RMBS going down after the ruling is my guess.
