Interesting volume today at nearly 60000 contracts. In particular one block for 32000 contracts went off at the same time as a 32000 contract block for the Dec $30 puts. Obviously the calls were bought on the ask for .05 so you could extrapolate a BTO position. However on the puts, that were sold an hour ago for 1.10, appears to have been on the bid price for a possible STO. I can not imagine this would be a STC, but I guess you wont know for 100% certainty.
