You are arguing that a one-percent intraday drop means that the "market hates it." And you are ignoring that the market (particularly the idiot day traders who tend to account for much of these sorts of small fluctuations) are heavily biased towards short-term results, often at the expense of long-term planning. LOL!
If the market thought this was a good business decision, CVS at the very least would not be trailing the overall market.
There is no arguing that.
You point regarding day-traders is ludicrous as day-traders trade ALL stocks, not just CVS. Any more excuses you have why the stock is down?
