Today’s tickers: CSCO, TJX & INSP CSCO  - Cisco Systems, Inc. –  Large risk reversals are dominating the options-landscape on Cisco Systems this morning, helping to drive volume above 540,000 contracts by midday in New York. The maker of networking equipment is the most active single-stock as measured by options volume today following the Company’s third-quarter earnings report after the close Wednesday.

Though a limited risk strategy, the spread could still result in substantial losses of up to $4.39 per contract in the event that TJX shares drop 16.4% to trade below $35.00 at expiration next month.
