Lar - That may very well be, although I can't see why someone would do that in the last seconds when a market order or even a limit at even .30 would have take out all the buys and given them a better sale. Not too smart to do as they did.
I'm still thinking it was more of a cross trade between two entities that showed up on the close. They may have not inteneded that as I've seen some large trades like that at low prices just after the close but the always registered in AH.
Who knows?
I wonder if the Amex will demand KRY issue a PR explaining the 80 - 100% gain today
