Before we try to understand how the VIX is calculated, it’s important to grasp the basics of options contracts. You pay a premium for the right, but not the obligation, to buy or sell a stock at a specific price (called the strike price) by a specific date (the expiration date). The higher the VIX, the greater the level of fear and uncertainty in the market, with levels above 30 indicating tremendous uncertainty. Active traders who employ their own trading strategies and advanced algorithms use VIX values to price the derivatives, which are based on stocks with high beta. Beta represents how much a particular stock price can move with respect to the activity of the broader market index.

In reality, the VIX simply measures expected volatility – the magnitude of potential price movements – Accumulation distribution indicator without indicating direction. A high VIX reading doesn’t necessarily mean stocks will fall, just as a low reading doesn’t guarantee market stability. The index merely tells us how much movement investors expect, whether up or down. Imagine the stock market has been steadily climbing for months, and the VIX index is hovering around 12.
The CBOE Volatility Index (VIX), often referred to as the “Fear Index,” provides a benchmark for the market’s future volatility expectations. It is a critical tool for investors and traders to assess market risk and sentiment, helping them make informed decisions. As the VIX tends to rise when markets decline and fall when they advance, it serves as an inverse indicator of market trends.
These prices reflect how much investors are willing to pay for protection against market swings. When uncertainty increases, the demand for options increases—and so do their premiums—leading to a higher VIX. Options trading entails significant risk and is not appropriate for all investors. Certain complex options strategies carry additional risk.

Following the popularity of the VIX, the CBOE now offers several other variants for measuring broad market volatility.

In many cases, when the stock market goes down in price, the VIX increases. That said, the VIX is intended to measure short-term volatility rather than act as an index that’s always moving the opposite way as stock prices. The VIX is an important barometer of market volatility and investor sentiment. Derived from S&P 500 options, it offers a snapshot of how fearful or complacent traders are feeling. From managing risk to trading options, the VIX has become a must-watch indicator for anyone serious about the markets. Known as the market’s “fear gauge,” the VIX often spikes during times of uncertainty and investor anxiety.
Investors use the VIX to gauge market sentiment, manage risk, and inform trading and hedging strategies, especially in options trading. Cboe uses a complex calculation to arrive at the VIX—a number that changes in real-time throughout the day like stock and other index prices. The calculation takes into account the real-time average prices between the bid and ask for options with various future expiration dates. There’s more to it, but basically, the VIX is calculated as the square root of the expectation of price changes in the S&P 500 over the next 30 days. The VIX measures the market’s expectations for volatility over the next 30 days based on the bid and ask prices of S&P 500 index options (called the SPX options). For instance, a stock with a beta of +1.5 indicates that it is theoretically 50% more volatile than the market.

When investors anticipate significant price swings, option premiums tend to increase, which then drives the VIX higher. Generally, the higher the VIX (as a result of increased options demand and thus prices), the less certainty investors have about future prices in the US stock market over the next 30 days. The lower the VIX (due to the lower relative options demand and prices), the more certainty investors may feel they have about US stock market prices over the next 30 days. The VIX tends to have an inverse relationship with the S&P 500’s price.
