It isn't because of buying though as volume is nothing(as smart money has bought in already-Goldman Sachs). This is short covering on a down day. Trying to be incognito about it. Smart way to cover your short is on a down day. But as I have been saying, there is 10M shares short this company out of just 34.5M that in all likelihood will be down to 33M by the end of 2013 due to the 79M still available to be used as buyback.
