The volume today was 4 1/2 million shares, about 5.5 times the normal volume. The selling is probably done or just about so, and the stock price will resume its upward trend next week. This is a bump along the road on a high hill to climb. CES next week won't hurt either to getting back on track. :-)
Unless there are some significant wins at CES next week, just expect the stock to languish around this level for a while until 1st qtr/fiscal year 2013 guidance is given. It will be interesting what Samsung's new TV is about...will it have Instaprevue? Will it have wireless HD integrated into it? Will it have MHL? If it has wireless HD integrated into it, that is a great sign for their new wireless chip making it into samsung's smartphones next year.
