I don't know nearly as much about stock as most people on this site, so bear with me because I have a potentially dumb question.

I agree that the timing of these sales looks really bad. However, I've heard that these guys are executives with an enormous amount of stock and the sales were for a small percentage of their overall stake. If they were intentionally breaking the law to avoid losses, wouldn't they sell all or most if it? Was most of their stock not vested and they just dumped what already vested? Or is the claim that it was a small percentage of their stock not true?
