Cboe Crude Oil ETF Volatility Index

The Cboe Crude Oil ETF Volatility Index^SM (OVX) is an estimate of the expected 30-day volatility of crude oil as priced by the United States Oil Fund (USO). Like the Cboe VIX Index^®, OVX is calculated by interpolating between two time-weighted sums of option mid-quote values - in this case, options on the USO ETF. The two sums essentially represent the expected variance of the price of crude oil up to two option expiration dates that bracket a 30-day period of time. OVX is obtained by annualizing the interpolated value, taking its square root and expressing the result in percentage points.
