The only thing I can speculate is that in late April, a ton of incentive shares from 2014 given to several officers, became "cashable". The only other guess is that if there is institutional ownership(ETFs/mutual funds/etc), the chief officer(s) lump selling triggered a bunch of bailing, due to stop limits.....
Kind of stupid, if the officers selling abruptly caused the days' decline.....They could have "trickled" their selling over several days/weeks, and the stock price probably wouldn't have dropped so hard.
Crazy speculation?
I don't see any other reasoning....
