Here's the most recent trend that continues to develop. You can respond by posting graphs that started months or years ago, but investors want to know what's going on RIGHT NOW. Since CVS refuses to offer full disclosure, I suspect there have been numbers leaked to some investors. Of course, because CVS hides their month-to-month sales numbers, we won't see the full extent of the damage until the May report. If CVS doesn't strongly warn about the upcoming failures during their Feb 6 "guidance", a class-action may be investors' only option.
