The CBOE Volatility Index has been hailed as a revolutionary instrument ever since its introduction in 1993. For more than a decade, VIX has been the preeminent barometer of market volatility and investor sentiment. Derived from real-time S&P 500 Index option prices, VIX is designed to reflect investors' consensus view of expected near-term stock market volatility over the next 30 days.
