That's to prevent downward trend in AH. Real big accumulators don't show their hands while accumulating. This one was meant to scare people from selling lower in AH, knowing the market is thin and it won't be filled. If I have to guess, that account probably has a lot riding on options.
just FYI i put in a stop @ $178.50 and sold at the open.Kudos to the people that went short.I got out with a $220 loss on my 1,000 shares,im happy.I should have sold in pre, the stock wasnt acting well.You were right, those shares last night were there to slow the momo down.
