CVS, which took a 20 percent hit Thursday after the company posted earnings and warned of a disappointing 2010 pharmacy benefits sales period, has been grinding higher and was recently trading near session highs. CVS is up 94 cents to $30.74 and now up 6.5 percent since Thursday. Morgan Stanley said today that Thursday’s sell-off was overdone and said “the co. will be able to fix its marketing problem.” Sentiment in the options market seems a bit more bullish today as well. 42,000 calls and 11,000 puts traded on CVS today. Trading is scattered across Nov, Dec and Jan options with strike prices ranging from 28 to 38. Nov 31 calls are the most actives.
