The Cboe Volatility Index (.VIX), an options-based indicator dubbed the Wall Street "fear gauge," jumped as much as 6.36 points to 28.97, before closing up 2.19 points at 24.8.
VIX options, used by traders to place wagers on whether stock market volatility will rise or fall in coming weeks and months, changed hands in heavy volume, with some 2.36 million contracts traded.
Much of the volume on Friday was linked to traders booking profits and adjusting positions to account for the recent market moves, data showed.
Betting on upside in the VIX has not been as profitable as many traders had hoped over the past year, despite a steep selloff in the stock market.
That gradual pick up in volatility has kept the VIX below the 40 mark, a level associated with high fear in the market.
