In hindsight after reading the posts, yesterdays drop of 10 cents equates to about 15% which is on average for the sector I guess.  As CBS notes though theselling may well have been stop loss selling and he is correct, the MM can see the stop loss orders being placed.  If the price trends back up then it was probably stop losses being triggered today.  however, as noted by Wintersun, the PR's from the company have been missing.  Folks get tired and begin to think the worst.
