CVS Health Corp. has no problem picking a fight this time of year - first, the company's prescription benefit manager arm started a beef with consumers subscribed to other PBMs, when it revealed plans to upsize charges for its clients who buy their prescriptions at pharmacies that sell tobacco. Next, the big beef started with CVS' and other retailers' decisions to reject Apple Pay at the register, which could create a stir with loyalists to the smartphone. However, it isn't hurting CVS shares -- yet. The company's stock is up nearly 20% as we get ready forearnings next week.
