The Cboe Nasdaq Volatility Index (VXN) is a financial metric that measures the market’s expectation of 30-day volatility in the Nasdaq 100 Index. It is often referred to as the “fear gauge” for the Nasdaq 100, reflecting investor sentiment in the tech-heavy marketplace.
How Does the VXN Work?
Calculation of VXN
The VXN is calculated using the prices of a wide range of Nasdaq 100 index options. These options include both calls and puts, and their prices reflect the market’s expectations for future volatility. More precisely, the VXN uses a weighted average of option prices to gauge expected volatility over the next month.
where:
- \( T \) is the time to expiration,
- \( \Delta K_i \) is the interval between strike prices,
- \( K_i \) is the strike price of the \(i\)-th option,
- \( R_f \) is the risk-free interest rate,
- \( Q(K_i) \) is the midpoint of the bid-ask spread for each option.
Types of Options Used
- Call Options: Gives the holder the right to buy the Nasdaq 100 index at a predetermined strike price.
- Put Options: Gives the holder the right to sell the Nasdaq 100 index at a predetermined strike price.
Historical Context of VXN
The VXN was introduced by the Cboe (Chicago Board Options Exchange) in January 2001. The index was developed to provide an additional tool for investors to gauge market volatility, particularly within the technology sector, which the Nasdaq 100 Index predominantly represents.
Special Considerations
High Volatility Periods
During periods of market turbulence, such as the 2008 financial crisis or the 2020 COVID-19 pandemic, the VXN tends to spike as uncertainty and risk increase. Conversely, in times of market stability, the VXN typically remains lower, reflecting calmer investor sentiment.
Comparisons to Other Volatility Indices
While the VXN tracks volatility for the Nasdaq 100, the VIX focuses on the S&P 500 Index. Both indices serve as market sentiment gauges but in different segments. The VIX and VXN often move in tandem but can diverge based on sector-specific events affecting the tech industry more heavily than the broader market.
Applicability of VXN in Investments
Making Informed Trading Decisions
Traders and investors closely monitor the VXN to anticipate market movements and manage risk. High VXN levels usually suggest caution and potential market downturns. Conversely, low VXN levels may indicate a stable market, encouraging investment.
Hedging Strategies
Options traders use the VXN to implement hedging strategies that mitigate the risk of large moves in the Nasdaq 100. For example, investors might buy put options if the VXN suggests higher expected volatility, protecting their portfolios from potential declines.
