I think a lot of them closed their positions today.
The stock bottomed out at about 4.85 and then climbed back from there.
At the time, sellers out numbered buyers by 2:1 and by 1pm they there was an even ratio.
That's not to say that more short positions would've been opened, but it would seem like such a larger risk to do. It seems that there is unanimous sentiment that it has been oversold and its very likely that some big players will jump in.
