Add to it a whole lot of wash trading today. Last stated O/S (end of September) was 20M shares, tossed over 13 times today (269M shares traded). December volume was in the 100-200k range per day. So somebody, large holder, maybe the folks who just did a deal with them for stock, waited for this "news" and turned their trading bots on.
Seems like a really dumb thing to do for a company claiming "manipulation," can they be less obvious?
