What is the VIX?
The CBOE Volatility Index (VIX) measures the market's expectation of 30-day forward-looking volatility in the S&P 500 index. Often called the "fear gauge," it calculates implied volatility from S&P 500 options prices, providing a real-time measure of market risk and investor sentiment.
How VIX is Calculated
Complex mathematical model:
- Options Data: Uses S&P 500 call and put options
- Strike Selection: Out-of-the-money options around at-the-money
- Time Weighting: Closer expiration dates have more weight
- Annualized: Volatility expressed as annual percentage
VIX Interpretation
Normal Range
- 10-15: Low volatility, calm markets
- 15-20: Normal market conditions
- 20-25: Moderate uncertainty
Elevated Levels
- 25-30: Increased anxiety
- 30-40: Significant stress
- 40+: Extreme fear, crisis levels
Historical VIX Spikes
Major volatility events:
- 1987 Black Monday: VIX reached 150+ (though VIX started in 1993)
- 1998 LTCM Crisis: VIX peaked at 45
- 2008 Financial Crisis: VIX hit 80+ during Lehman collapse
- 2020 COVID Crash: VIX spiked to 82 in March
- 2022 Rate Hike Fears: VIX reached 36
Mean Reversion
VIX tends to mean revert to its long-term average around 20. Extreme spikes are typically followed by declines, though timing is unpredictable.
