VIX (fear index)

Trader's Glossary · Broad market

VIX (fear index)

Definition. An index published by Cboe that measures the market's expected volatility of the S&P 500 over the next 30 days, calculated from option prices.

How it works

When investors buy more downside protection, option prices rise, and VIX with them. That's why it's called the “fear index”. It usually moves opposite to the stock market.

Example

In periods of panic VIX spikes, and the typical daily range in stock indices widens.

What to watch out for

VIX measures expectations, not the future. A high VIX doesn't mean the decline will continue.
