From what I’m able to gather, that is a filing from March 31. It encompasses all trading from the entire quarter. It could have been sold on Jan 2 or March 30 (or 300,000 shares a day for weeks), the filing would LOOK the same.
I am not saying they didn’t have an underwater device set up in the Gulf to detect any seismic activity in order to warn them of impending disaster, but in all likelihood it has nothing to do with the explosion, which occurred in late April.
