It is a false rumor and shows how bad seeking alpha is with facts. Anybody can write whatever they want. Ever hear of insider info? Well, if the company would get such an offer and not formally submit the offer to the shareholders, then go and reject it, they or those they tell now know info the public doesn;t such as how much a potential buyer likes DECK and at what price(which would initially be a low-ball offer). So under that knowledge they can then trade ahead and then get indicted.
So no, we would know if there was an offer. We are up on the DELL buyout news.
