Comcast failed to hold early gains yesterday, prompting one bear to make a large bet against the stock late in the session.
OptionMonster's tracking programsdetected the purchase of about 25,000 July 15 puts for about $1.01 and the sale of about 22,500 July 17 calls for $0.77. Volume was more than four times open interest in each strike.
The cable giant fell 1.96 percent to $15.97 and is down 5 percent in the last month. CMCSA surged to an 11-month high in early December after the company announced a plan to purchase a controlling stake in NBC Universal from General Electric .

The company reported better-than-expected sales and earnings yesterday morning but fell after saying it was spending more money to add customers.
The option trade, known as a bearish risk reversal, is designed to leverage a move to the downside. It was broken into several parts with multiple canceled transactions, but the trader paid a net debit of about $0.33 for each put contract purchased.
The strategy, which uses income from selling calls to pay for the puts, mimics a short position in the stock and will lose money if Comcast rallies over $17. The transaction pushed overall options volume in the name to more than eight times greater than average.
