Trading in stocks and options yesterday was dominated by the election results. About the only sector to advance was the hospital sector. In PSS World Medical Inc. (PSSI), there was a buyer of 6,000 Dec calls. This was 7x normal volume and is likely a result of more certainty around Obamacare. In green energy (energy-from-waste renewable) company Covanta Holdings Corp (CVA), there was a buyer of 4400 Jun 17.5 calls opening. This was 35x normal and clearly a play on more government green energy investing. In auto parts supplier Gentex Corp (GNTX), there was a buyer of 4,000 Dec 20 calls. This was 15x normal volume.
