Today’s tickers: EWJ, RX, UUP, DRI, IMAX, SFD & AET

EWJ - iShares MSCI Japan Index Fund – Shares of the Japan exchange-traded fund rose 0.3% today to $9.92. The roughly 125,000 contracts exchanged on the fund today is likely the work of one investor adjusting previously established positions. The trader may be unraveling a portion of a bearish risk reversal established back in late-September. It appears 62,500 puts were sold at the March 10 strike for 53 cents apiece, spread against the purchase of the same number of calls at the January 2011 12 strike for 24 cents premium each. The technically bullish direction of the risk reversal play is possibly a closing transaction given the large levels of existing open interest at each strike described above.

RX - IMS Health, Inc. – Shares of the provider of prescription information to the pharmaceutical and healthcare industries plummeted 14% to $18.34 at the start of the trading session.

Some traders appear to be selling call options to buy puts in the December contract, while other investors initiated plain-vanilla put buying strategies. Bearish individuals shed more than 6,000 calls at the December 20 strike for an average premium of 46 cents apiece. Traders keep the premium received on the sale if shares of RX remain below $20.00 through expiration. Put buyers favored the December 17.5 strike where roughly 10,000 puts were picked up for about 46 cents each. Some of the puts were spread against the sale of higher strike call options, while other contracts were purchased outright. Roughly 5,000 puts were purchased at the lower December 15 strike where investors paid an average of…
