Cisco (CSCO) loses 12 cents to $17.91 and a Jan 17.5 – 19 strangle is sold on the networking company at $1.59, 4000X. The position is possibly closing, as both contracts have substantial open interest, and seems to be bet that shares will hold between $17.5 and 19 through the January 2012 expiration. After falling to 52-week lows of $13.73 on Aug 10, CSCO has been grinding it out over the past few months and is up 30.6 percent since that time. Meanwhile, implied volatility in the options on the stock is moving up 7 percent to 44 today, compared to a 52-week high and low of 67.5 (8/10) and 18 (12/20).
