I saw some hints of fund (i.e., non-retail) activity this afternoon at 1.30 and even a computerized buy or sell program 2-3 times, which I don't recall ever having seen at this price level. Keep an eye on ASCM, in particular - either he is sucking in a lot of stock, or another MM is matching his bid in stealth mode.
Also, the 50,000 backprint at 1.17 just now is interesting. I do believe the selling is done.
