Pfizer (PFE) is up 30 cents to $20.30 and more than 10K Feb 20 calls traded early, including a block of 8145 on the bid, 62 cents per contract. Shares of Pfizer are the best gainer in the Dow Wednesday morning after Republicans gained a Senate seat following the Scott Brown victory in Mass., which will make it more difficult for Obama to push through his healthcare reform. Consequently, healthcare stocks are showing relative strength and some players appear to be selling-to-close positions in PFE calls, which had been accumulated in the days leading up to the election.
