In the midst of one of the lowest volume trading days of the year it took little effort to push S&P 500 futures down. The ES futures themselves closed below 1200 for the first time in sometime. While light volume can be a good reason to ignore the markets do not forget that Black Monday was actually a low volume day. On most days when the market is down big the average volume is going to be much lower than when the market is UP big. So should traders be scared? Is this 'break out' toward 1200 low?
