The S&P 500 rose about 2% in December as the Trump rally rolled on, but that didn't stop a large number of individual investors from locking in gains. The behavior-based TD Ameritrade (AMTD) - Get Report Investor Movement Index, or IMX, which aggregates Main Street investor positions, fell 1% to 5.48 in December as retail investors slightly decreased their exposure to the U.S. equity markets for the second month in a row. The VIX, or so-called fear index, ticked started and finished the month at 14.
