Thanksgiving Day creates its own set of trading risks. Today Wednesday before is one of the biggest travel days. All forms of transportation are stressed and many people away from the desk. If you are at the desk to many people away from the desk to make substantive decisions.
Therefore do you trust the trading volume. Even with the plethora of mobile devices many will not be in a position to trade. The price action and volume you are looking at does not fit the norm of two standard deviations.
This will also be true on Friday with limited market participation.
