Simply based on the history of previous trades of size in the name, I'd be willing to wager those large blocks at the end of the day just went from weaker hands into stronger hands looking for much higher prices in time.
Looking forward to Monday and the company's debut on Nasdaq, right where it belongs.
Cheers to management for their exceptional efforts on shareholder's behalf and to a great group of quality people in this forum whose sharing of information has served us all well thus far.
