Yeah, that's pretty messed up. I checked and the next highest trade was 100 @ 66.00
9:30:00 100 68.205
9:30:11 100 66.00
Perhaps it was a fat fingered / directed trading error that didn't even effect the rest of the trades. Somebody won the lottery with that sell, I guess. Curious that it goes out to the third decimal place though. If it was a directed trade, I don't know how that would happen.
