What Is the VIX Index? A Complete Guide

Estimated reading time: 3 minutes

Volatility and fear are constant companions in the financial markets. To decode these emotions, professional investors turn to a powerful tool: the VIX Index, also known as the “Fear Index.” But what is it exactly? How does it work? And how can you use it to manage your risk like a pro?

Let’s break it all down.


What Is the VIX?

The VIX (Volatility Index) measures the expected 30-day volatility of the U.S. stock market, based on S&P 500 options prices. Created by the Chicago Board Options Exchange (CBOE), it’s a real-time gauge of market sentiment and investor anxiety.

  • When volatility expectations rise, the VIX increases 📈
  • When the market is calm and confident, the VIX falls 📉

Often dubbed the “Fear Index”, it signals how nervous—or confident—investors are about the near-term future.
