Well, today we saw SSCI...but as you imply, sumpin' yet could could happen (shell play).
The biggest one that comes mind right now is that goofy lil oil company right near us... P-something. I came home one mid-afternoon about, oh, a year and a half ago, and saw it up about 500%. I thought, no way...Of course, it ran about 1,200% by EOD...then doubled the next day, ie, another 100% ...
As i recall, their little PR was claiming access to/contracts for more reserves than are known in Texas...
I think they've had some minor flurries since then, but never another "big day."

Ahhh, and of course... QBID: only one big run there, I think. That may have been more than one day, though...
