Great post by Mackwheaton a couple back.
I have been trying to play out scenarios for the past half day to understand what happened and here goes. Pure speculation:
LP informs his broker that he wants to cash out 1.5 million bucks for whatever reason, LP has over 3million options and 500k shares. The broker/other shareholder says ok and will call @2pm. The broker sells through the day to get 1.5 million bucks in his account knowing he can buy back at the end of the day. around 2pm, the broker calls LP and says I have 1.5 mill in the account, push the sell button, knowing there are not many buyers, because the crap is scared out of them, the broker buys back over 750k shares around the end of the day.
This way, we only have one day of insider sells, because if it went on repeatledly, we have 2011/2 all over again. this way LP gets the most from his shares, in one day.
Pure speculation,
