My guess is that shorts are sizing up the playing field and know things could dramatically turn against them - it became increasingly clear thorughout the day that there is lots of octane to move up. Thus, the potential for this exit point could continue to diminish, and thus they took it. It doesnt make any sense that these were bought to put naked short shares into the float as being argued yesterday, as we are on an up swing. I guess it could still be just another short bet if the calls were sold by shorts, although that wasnt really consistent with the vibe of the afternoon.
I doubt the shorts are all working with the same knowledge of a hit piece coming... I would guess they see mauraders moving in and want a peice of the actions - just like day traders. But what do I know...
Isnt the put open interest overall higher than yesterday.
