Estimated reading time: 3 minutes
Table of contents
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.
Key Features of the VIX
| Feature | Description |
|---|---|
| Unit | Annualized % of expected volatility |
| Inverse to Stocks | Tends to rise when stocks fall |
| Sentiment Tool | Reflects investor fear or calm |
| Risk Management Use | Supports hedging & strategic planning |

How to Read the VIX: Levels & Interpretation

|---|---|---|
| 🟢 Below 15 | Calm | Optimistic investors, low fear |
