iPath S&P 500 VIX Short Term Futures (VXX) adds 28 cents to $16.88 and a noteworthy trade Wednesday is a block of 35,000 December 19 calls bought at $1.35 per contract. Looks like an opening position and perhaps a volatility play ahead of key economic data over the next two days (GDP, jobless claims, PMI Thursday then personal income/spending, UofMich Sentiment, construction spending, ISM, and auto/truck sales Friday.)
