A methodology was adopted that remains in effect and is also used for calculating various other variants of the volatility index. VIX values are quoted in percentage points and are supposed to predict the stock price movement in the S&P 500 over the following 30 days. The VIX formula is calculated as the square root of the par variance swap rate over those first 30 days, also known as the risk-neutral expectation.

When the VIX index moves higher, this reflects the fact that professional investors are responding to more price volatility in the S&P 500 in particular and markets more generally. When the VIX declines, investors are betting there will be smaller price moves up or down in the S&P 500, which implies calmer markets and less uncertainty. The VIX is considered a reflection of investor sentiment and has in the past been a leading indicator of a dip in the S&P 500, but that relationship may have changed in recent times. For instance, in the three months between Aug. 8, 2017, and Nov. 8, 2017, the VIX was up 19%—seemingly suggesting anxiety among market participants and implying that the S&P 500 should be on a downward trajectory.
