What Is the VIX? Meaning, How to Read It, and Investment Uses
What Is the VIX?
The VIX (Volatility Index) is a real-time index calculated by the Chicago Board Options Exchange (CBOE) that measures expected volatility in the S&P 500 over the next 30 days. Often called the "Fear Index," it reflects the level of anxiety among market participants.
Why Does It Matter?
The VIX serves as a thermometer for investor sentiment. Generally, a VIX below 20 signals market stability, while readings above 30 indicate significant fear. During the 2008 financial crisis, the VIX exceeded 80, and it spiked to 82 in the early days of the 2020 COVID-19 pandemic.
When the VIX surges, equity markets tend to decline. Conversely, an extremely low VIX may signal complacency—a potential warning that markets are too relaxed. This makes the VIX valuable not just as a fear gauge, but also as a reference for market timing.
