Hedge funds collaborate? Firstly, likely illegal. No compliance department would ever sign off on it even if it were legal. Secondly, most hedge funds would eat their young. Could you imagine the day one tried to cover before the other? “Oh , didn’t I tell you? “. My suspicion is the short is on OR those 5 stroke puts were a short against the box (later is unlikely) so, at some point those shares have to be delivered to those who sold the puts. That means , inevitably a covering trade. I missed the expiry on those. Anyone know?
