VIX
The Cboe Volatility Index: a measure of the S&P 500's expected 30-day volatility implied by option prices, often called the fear index. VIX spikes during selloffs and decays in calm markets. It is not directly tradable — products like VIX futures and the ETFs built on them carry structural roll costs that make them decay over time, which any strategy touching them must respect.
