Volatility skew is a significant concept in options trading, describing the observed pattern where implied volatility varies for options with different strike prices but the same maturity. This phenomenon can provide key insights into market sentiment and potential price movements, influencing options trading strategies. In this article, we will explore what volatility skew is, how it affects options pricing, and strategies traders can employ to capitalize on or hedge against this skew.

Understanding Volatility Skew

Volatility skew reflects the market’s varying expectations of volatility across different strike prices, leading to an asymmetrical pricing pattern in options.

Causes of Volatility Skew

Several factors contribute to the creation of volatility skew. One common reason is investor sentiment, where market participants might have greater concerns about significant downward movements (especially in bear markets), resulting in higher implied volatilities for lower strike prices. Supply and demand dynamics for options at various strikes also play a role.

Types of Volatility Skew

  • Vertical Skew: Occurs when options with different strike prices (but the same expiration date) have different levels of implied volatility.
  • Horizontal Skew: Happens when options with the same strike price (but different expiration dates) exhibit varied levels of implied volatility.

Strategies for Trading with Volatility Skew

Understanding and utilizing volatility skew can be advantageous in formulating effective trading strategies.

Trading on Market Sentiment

Traders can use the information from volatility skew to gauge market sentiment. A steeper skew might indicate stronger fear of downside risk. Traders can design strategies around this, such as protective puts if they anticipate market downturns, or contrarian plays if they believe the market is overly pessimistic.

Spread Trades

Volatility skew can be exploited through spread trades. For instance, traders might use a calendar spread, buying long-term options with lower implied volatility and selling short-term options with higher implied volatility. Vertical spreads can also be used to take advantage of differences in implied volatility across strike prices.

Considerations and Risks

Trading based on volatility skew requires careful consideration of market dynamics and inherent risks.

Monitoring Market Changes

Volatility skew is dynamic and can change rapidly based on market conditions. Traders need to stay updated on market news, economic indicators, and sentiment shifts, as these can all influence the skew.

Balancing Risk and Reward

Strategies based on volatility skew should balance potential rewards against the risks. For example, while selling options with high implied volatility can be profitable, it also increases the risk of significant losses if the market moves against the position.

Understanding Option Greeks

A thorough understanding of the Greeks, especially Vega (sensitivity to volatility) and Delta (sensitivity to the underlying asset’s price movement), is essential when trading with volatility skew. This knowledge helps in managing the portfolio’s overall risk.


Volatility skew offers a nuanced perspective on market sentiment and implied volatility, presenting unique opportunities for informed options traders. By understanding and strategically responding to volatility skew, traders can develop sophisticated strategies to exploit market inefficiencies or to hedge existing positions. However, success in these endeavors requires a comprehensive understanding of market dynamics, continuous monitoring of market conditions, and a keen awareness of the risks involved in options trading.
