How to read it
A VIX of 20 implies the market expects the S&P; 500 to move about 20% annualized, or roughly 5.8% over the next month. Calm markets sit in the teens; the VIX topped 80 in both the 2008 financial crisis and March 2020. Because it spikes during selloffs, it's nicknamed the fear gauge.
VIX product pitfalls
You can't buy the VIX directly—only futures-based ETFs and ETNs. Constant rolling into pricier futures (contango) makes them bleed value over time. In the February 2018 "Volmageddon," some inverse VIX products lost over 90% in a day. Buying when fear peaks is a classic contrarian idea from behavioral finance.
