Why One Big Trader is Grabbing Comcast Options

David Russell|writer, OptionMonster

Comcast started rallying this month, and one large investor expects it to keep moving higher through January.

's tracking systems detected the purchase of 10,000 January 17.50 calls for $1.05 and the sale of an equal number of January 16 puts for $0.95. Volume exceeded open interest in the puts but not the calls.

CNBC/ Trading School:


CMCSA shares rose 1.38 percent to $16.92 in Monday afternoon trading. The cable stock is up 8 percent in the last month and is rebounding after finding support around the $16.60 level.

Today's options trade is designed to leverage small gains in the share price into big profits. It cost a net debit of just $0.10 per call contract purchased, meaning the investor will double his or her money for about every $0.10 that CMCSA climbs above $17.60 by expiration. Given the short position in the puts, it will lose money below $16.

The next potential event that could serve as a catalyst for the shares is the release of third-quarter earnings before the bell on Nov. 4. CMCSA reported better-than-expected earnings and revenue the last time it reported on Aug. 6.

Overall options volume in the name was almost three times greater than average today.
