What: Shares of drug developer Exelixis
So what: Investors got fired up after Bloomberg reported that Exelixis is working with Goldman Sachs to field potential buyout offers after its prostate cancer drug showed promise in a study late last year. As it is, the company's stock has more than doubled since the positive data on XL184 was published Nov. 17, but investors could see further gains if a buyer with deep pockets steps in to snap up the company. After a partnership with Bristol-Myers Squibb
Now what: Both the company and Goldman are staying mum on the situation. I tend to be very skeptical when it comes to speculating on potential buyouts. Certainly there's a very plausible story here -- Exelixis has a promising treatment and the big pharma players need new drugs and have truckloads of cash to spend. However, investors may want to stay focused on the longer-term prospects for Exelixis on its own rather than gambling on the potential for a quick bump from a takeover.
