The VIX (CBOE Volatility Index) measures implied volatility for the S&P 500 over the next 30 days, derived from options prices. It is often called the market's fear gauge — VIX above 30 signals elevated market stress and uncertainty; below 15 signals complacency and low expected volatility.

What does a high VIX mean for stocks?

VIX above 30 typically coincides with market selloffs and elevated investor panic. Historically, buying broad market exposure when VIX spikes above 40 has been profitable over 12-month horizons — fear tends to be highest near market bottoms, not at the start of declines.

What is a normal VIX level?

The long-term average VIX is around 19–20. Below 15 signals compressed volatility and potential complacency — extended low-VIX periods are often followed by sudden spikes. Above 25 signals elevated uncertainty; above 40 signals market crisis conditions.

How does the VIX affect options prices?

Higher VIX directly increases options premiums — both calls and puts become more expensive because the market expects larger price swings. Options sellers (who collect premium) prefer high-VIX environments; options buyers face higher breakeven thresholds.
