The $vxx is an ETF that tries to mimic the Volatility index VIX. It tries to to this buy purchasing front month $vix calls and keeping a 30 day maturity. Historically $vxx makes a new 52 week low in December due to lack of volatility, less trading days, and the markets usually melt higher during the holidays at the end of the year. Shorting $vxx or going long $xiv is a good trade here with a stop 5 percent from your entry in case the market does turn. For the bold, shorting $tvix and $uvxy can be a nice trade as well for a day, week, or for the month of December.
