There are 17 so far that I have seen since last night. Not all are upgrades there are 10 that are near or under the current pre-market price. I believe that these firms may believe that margins have peaked. Of course some of them were probably behind the share price recently and some are just probably non-believers. Either way the shares are where they are now and that's what you trade if you trade. If you are an investor from lower prices you have done well along with the dividend. This new CEO has done a much better job the last one. I personally believe the shares are near an inflection point based on the level of their margins.
