Most Traders Use IV Rank to Pick Trades. Here's Why That's Only Half the Answer.

SPX

The speaker suggests that the skew in implied volatility for SPX options, such as the 6750 puts with 17.46 volatility and the 6730 puts with 17.8% volatility, indicates a potential opportunity for a volatility trade. The IV rank of 41% and the overall volatility of 19.7% are used as indicators to identify the market's interpretation of the option's value. The trade idea is to exploit the skew by entering a position that benefits from the differing volatility levels, with the expectation that the market's skew will continue to reflect the underlying asset's risk profile.

Understanding Implied Volatility Skew

Implied volatility skew refers to the phenomenon where different strike prices of options have varying volatility numbers. This skew arises because the Black-Scholes model assumes a single volatility input for pricing, but the market provides different implied volatilities for each option. The skew reflects the market's interpretation of the option's value, translating into deltas, Greeks, and probability numbers. The skew is not a model's output but a market-derived metric that provides insights into the perceived risk and potential price movements of the underlying asset.

Use of Implied Volatility in Trading Decisions

Traders should use implied volatility (IV) as a key factor in their trading decisions. The speaker explains that IV rank and overall volatility can help identify opportunities, but the final trading decisions should be based on metrics derived from implied volatility, such as delta and probability numbers. These metrics are crucial for understanding the risk and potential of an option.

What is implied volatility skew?

Implied volatility skew is the phenomenon where different strike prices of options have varying volatility numbers. This skew reflects the market's interpretation of the option's value, translating into deltas, Greeks, and probability numbers. It is not a model's prediction but a market-derived metric that provides insights into the perceived risk and potential price movements of the underlying asset.

TakeawayImplied volatility skew is a market-derived metric that reflects the perceived risk and potential price movements of the underlying asset, and it is used to inform trading decisions.

How do you use implied volatility in your trading decisions?

The speaker explains that implied volatility (IV) is used to identify opportunities, with IV rank and overall volatility as initial indicators. Final trading decisions are based on metrics derived from implied volatility, such as delta and probability numbers. These metrics help assess the risk and potential of an option.
