Interesting flow in the weekly options that expire next Friday and therfore include the potential US default event. On the stock side call buyers appear to dominate, with BAC 10 and 11 strike calls trading actively and AAPL and RIMM upside calls busy in offer-side flow with increasing IV. On the ETF side the volume is in the puts, with SPY 128 strike puts for 8/5 expiration leading the list and an early buyer paying 1.95 for nearly 8000 contracts on the CBOE.
