The price of these options is influenced by several factors, including the current stock price, the strike price, the time until expiration, and, crucially, the expected volatility of the underlying stock. The VIX index distills all the information from these options prices to generate a single number representing market expectations of volatility. The year 2003 marked a pivotal moment in the VIX’s evolution when it underwent a significant methodology update, shifting its calculation to S&P 500 (SPX) options.
- The complex nature of these derivatives means their returns can significantly deviate from what investors might expect based on VIX movements alone.
- Alternatively, VIX options may provide similar means to position a portfolio for potential increases or decreases in anticipated volatility.
- It is a critical tool for investors and traders to assess market risk and sentiment, helping them make informed decisions.

VIX index: How Wall Street’s ‘fear gauge’ measures stock market volatility
Rather, it’s a leading indicator that measures the level of stock market volatility expected by investors. In this article, we’ll delve into what the VIX measures, how it’s calculated, and whether you should use it in your investment decisions. Unlike historical volatility, which looks at past market movements, the VIX is forward-looking. It represents implied volatility, or the market’s forecast of future movement. When investors expect turbulence—whether due to economic data, earnings reports, geopolitical events or policy changes—they often buy more options to hedge their positions.
Understanding the CBOE Volatility Index (VIX) in Investing
Following the popularity of the VIX, the CBOE now offers several other variants for measuring broad market volatility. Traders can use VIX futures, options, and ETFs to hedge or bet on changes in the index’s volatility.In general, volatility can be measured using two different methods. The first method is based on historical volatility, using statistical calculations on previous prices over a specific time period. This process involves computing various statistical numbers, like mean (average), variance, and the standard deviation on the historical price data sets. The VIX index is a popular measurement for traders to quickly judge market volatility. It can Grid trading also provide trading opportunities, with some traders using it to diversify their portfolio or others as an effective hedging tool.
CBOE Market Volatility Index (VIX)
After 2002, Cboe based the VIX on S&P 500 options to better capture market sentiment. When you invest in oil, you take full ownership of the asset and are required to transport and store the commodity, which can be a difficult process. Alternatively, some traders may prefer to speculate on oil’s price movements without owning it outright, although this also comes with risks of leverage and short-term volatility, as the market can turn at any point. Investors use the VIX to gauge market sentiment, manage risk, and inform trading and hedging strategies, especially in options trading. Volatility is one of the primary factors that affect stock and index options’ prices and premiums. As the VIX is the most widely watched measure of broad market volatility, it has a substantial impact on option prices or premiums.
- After 2002, Cboe based the VIX on S&P 500 options to better capture market sentiment.
- Such VIX-linked instruments allow pure volatility exposure and have created a new asset class.
- A VIX reading of 20 might be considered high during a calm bull market but relatively low during periods of economic uncertainty.
VIX Index (1 month)
VIX futures are derivatives based on the VIX Index, allowing investors to trade on future volatility expectations. Some investors fall into the trap of using the VIX as a precise timing mechanism for market entries and exits. High VIX readings don’t automatically signal market bottoms, nor do low readings immediately precede tops.
Yes, investors often use the VIX as a hedge against other portfolio assets, speculating on or mitigating the impact of volatility. Yes, there are several ETFs and ETNs designed to track VIX futures, offering exposure to volatility without directly trading options or futures. Analysts and market experts have been heavily critical of the volatility index trading as this index is often used to predict the future market volatility. Let us understand their perspectives and why the criticism arises often through the explanation below. The volatility index strategy is being used for determining the movements in the stocks of the S&P 500. When this relationship doesn’t follow for a particular period, the present direction of stocks is said to be unsustainable for a short period.
As a result, many traders use exchange-traded funds (ETFs) or exchange-traded notes (ETNs) that are tied to the index to gain exposure to it. Additionally, besides trading the VIX, many traders have adopted it as a useful indicator of market volatility. It is also used as the backbone of many products that are based on volatility indices.
Term Structure Trading
In 1993, the VIX was first calculated using the implied volatility of eight S&P 100 at-the-money options. There are many ways that traders use to profit from or to protect themselves by using the VIX. These include buying VIX futures as a volatility hedge or mean reversion techniques via futures or using inverse VIX ETFs. Also, traders can engage in volatility arbitrage by taking positions in VIX futures and offset these positions with VIX-related products.
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 Chicago Board Options Exchange Volatility Index, commonly known as the VIX, emerged in 1993 as a groundbreaking tool that would forever change how investors measure and interpret market fear. Commissioned by the CBOE and developed by Professor Robert Whaley, the index initially focused on S&P 100 (OEX) options before evolving into its current form. Many traders use Saxo Bank International to research and invest in stocks across different markets.
Understanding the VIX can provide valuable insight into market expectations and investor sentiment, helping you to manage investment risk and make more informed decisions. When market fear is high, so is the price of the VIX index, whereas a lower VIX price can be a sign of either greed or investor complacency. Using the index alongside other measures of volatility and market outlook can help to provide crucial clues into current investor sentiment and an index’s prospects. Combining multiple models and inputs in your trading can provide you with less risk exposure when compared with betting on a single variable.
Astute investors tend to buy options when the VIX is relatively low and put premiums are cheap. For instance, a stock with a beta of +1.5 indicates that it is theoretically 50% more volatile than the market. Traders making bets through options of such high beta stocks utilize the VIX volatility values in proportion to correctly price their options trades.
Following this weekend’s strikes by the US, oil markets remain fairly stable as investors wait for Iran’s response. WTI 1M implied volatility surged to as high as 68% last week before ending the week at 51%. The WTI 1M implied-realized vol spread has halved from a high of 30 pts to 14 currently, as fears of significant oil supply disruption have abated somewhat. Notably, US inflation expectations have barely budged on this latest jump in oil prices, in sharp contrast to the 2022 Russia/Ukraine invasion. Many investors assume that VIX ETFs and futures will perfectly mirror the performance of the VIX index itself. These products often behave quite differently from the underlying index due to factors like contango, backwardation, and their own structural characteristics.
