CBOE S&P 500 9-Day Volatility Index (VIX9D)
The CBOE S&P 500 9-Day Volatility Index SM (VIX9D) estimates the expected 9-day volatility of S&P 500® stock returns. Similar to VIX®, VIX9D is derived by applying the VIX algorithm to options on the Standard &Poor's 500 Index (SPX options), but it uses SPX options with expiration dates that bracket a nine-day period of time.VSTN and VSTF are variations of VIX9D that estimate the expected volatility of S&P 500 stock returns from the near term and far term SPX option series used to calculate VIX9D.
