One of the largest volume leaders in option land today belongs to Comcast (CMCSA). With the stock just over $45, over 50,000 of the March 50 calls have traded mostly around $.23 zone. Comcast sat out much of the Dec and early January rally, with the stock muddling along in the low to mid 40’s. Should buyers come searching for cheap lagging names, Comcast (along with others, e.g. Pfizer) might be a prime candidate. I am speculating but my guess is this type of reasoning might be driving some of this option activity, as $50 level would easily eclipse the current 52 week high of $47.25 hit in Sept of last year.
