Small investors bet big on oil as the commodity hit a new six-year low Wednesday, according to data from TD Ameritrade exclusive to CNBC Pro.

The impulse from retail investors to get behind oil is not new, as we have previously reported on this trend.

This time, however, the investment vehicles chosen to bet on a potential rebound are "much more aggressive," notes JJ Kinahan, chief market strategist at TD Ameritrade.
