CVS touches a new 52-week high today and is up a dime to $39.90. The top options trade on the stock is a 14,200-contract block of Jan 40 calls, bought for $1.24 per contract on CBOE. It’s possibly closing, as the contract is now at-the-money and has 43,136 in open interest, which is the largest position in the name. 16,800 now traded. Or, it might be a bullish play on CVS the day after the company backed its guidance and announced plans to raise its dividend. Shares rallied 8.8 percent on the news yesterday.
