This is a crutial day. The stock is toppy and starting to come down and the news for now, all seems out.The big managers are going to tip their hand slightly in this upcoming final hour today. The little guys have to be watching carefully.
Looks like you hit that nail squarely on the head.
However, the volume isn't so disconcerting. Looks like a normal correction to me; one to be expected from such a steep run-up.
