RE: RE: RE: I love MDX but I don't understand why I have a buddy who works for Costco and gets shares He had sold them a while ago - they are basically his pension. He had to put his buy order in when he wanted to buy them back 2 days beforehand. 2 days earlier the stock had spiked up and they likely were thinking it would continue. They also have to be careful about the news release timing when they buy and sell.
