Because the AH price depends on the traded price of the stock it would be in the buyers interest to control the price if they can. That could be one theory, someone like MS won't want to pay around 20+$ for buying if this would have run in the last week.
I can. Just like the 100 share lots, anytime CCME has tried to run hard there is always the selling which keeps the momentum from ever building. 150k shares of sells a day to go along with the regular shorting and naked shorting is a lot to absorb. If we are truly done with those 150K shares being sold each day, that will help a lot IMHO.
As per my post this AM on the CGS board (before Shermadog's find of the odd lots that nailed the case of Ping Lin's selling), it's not so much the selling of 150K AH blocks itself that capped this stock over the last 4-5 weeks but the fact that it has been very likely brokered by MS in an attempt to buy those shares for their clients on the cheap (and make those shares immediately available for shorts in order to keep a lid on the SP for the duration of the whole 1M+ share-transaction as per Newport's post). That's the only reason I see why MS has been holding back that much anticipated coverage report (that you claim was finished weeks ago) and why the Company hasnt come out yet with an update for Q4 and 2011 and other big positive news that we are all expecting. I think that Mgmt is acting here in concert with MS in order to help Lin exit in an orderly discrete manner and satisfy MS' clients at the same time before they all release the news. Now that the selling is done, let the good news come!
