Frequently Asked Questions
What is the VIX fear gauge?
The VIX, or CBOE Volatility Index, measures how much movement investors expect in the S&P 500 over the near future. It is calculated from the prices of S&P 500 options, which act like insurance against big market swings. When investors feel nervous, they pay more for that protection and the VIX rises. When they feel calm, the VIX typically falls. It is a measure of expected volatility, not a tradable stock.
What does a VIX reading of 14.84 mean?
A VIX reading near 15 generally signals that investors expect relatively low volatility in the S&P 500 over the coming weeks. The index is quoted in points, and each point roughly corresponds to an annualized expected move in the index, so 14.84 implies moderate calm. Readings well above 20 typically reflect elevated anxiety, while readings in the low teens suggest a relaxed market mood. It is one indicator among many, not a forecast of direction.
Why does the VIX usually move opposite to stocks?
Stock declines tend to make investors anxious, which increases demand for options that protect against losses. Higher demand raises option prices, pushing the VIX up. When stocks rise, investors generally feel more confident, reduce hedging, and the VIX tends to fall. This inverse relationship is common but not guaranteed, and the VIX can rise during quiet periods if sudden news changes expectations.
Can the VIX predict stock market crashes?
No, the VIX cannot reliably predict crashes or direction. It measures expected movement, not whether prices will rise or fall. A low VIX does not guarantee a calm market, and a high VIX does not guarantee a decline. Because it looks forward and reacts quickly to news, it is best used alongside price trends, economic data, and other indicators rather than as a standalone signal.
