PowerShares US Dollar Bullish Index Fund (UUP) Nov 23 call is the most actively traded options contract for a second day. Volume surged to more than 330,000 contracts and the heavy trading left many of us wondering: why? Was it a play on the FOMC announcement? Were these call buyers also playing the actual currencies and looking for some type of arbitrage opportunity? Does somebody know something?! As it turns out, UUP shares were halted today and hit a high of $23.15 on news the fund is no longer issuing new shares. Now, with another 192,000 Nov 23 calls traded (35% bid / 33% mid / 32% ask-side), it appears that some “savvy” players might have anticipated today’s news and now appear to be exiting Nov 23 calls at prices ranging from 15 to 35 cents — after many positions opened yesterday morning at 15 cents.
