Quick Facts
Definition: Implied Volatility Skew Trading involves analyzing the differences in implied volatility across various strike prices of the same underlying instrument to optimize options pricing strategies.
Purpose: The goal is to capitalize on an undervalued or overvalued market where implied volatility is skewed.
Instruments: This strategy can be applied to equity options, ETF options, and exotic options like binary options.
Analytical tools: It requires tools like Implied Volatility (IV) charts, option Delta-Gamma-Heta surfaces, and statistical models like Monte Carlo simulations.
Market conditions: Implied Volatility Skew Trading is more effective during times of high market volatility and when there are significant events causing price movements.
Types: There are three main types of IV Skew: (1) Roll-Ihara, (2) Jensen’s Inequality, and (3) Put-Call Skew.
Common metrics: Implied Probability Skew, Mid-Point Implied Volatility, and Directional Implied Volatility are used to measure IV differences.
Risk management: IV Skew Trading requires hedging strategies to minimize losses, as large movements in the underlying asset can quickly negate trading gains.
Best suited for: Institutional traders, quantitative traders, and high-frequency traders due to the complex analytical requirements and high potential returns.
Potential returns: IV Skew Trading can provide significant returns, but it’s a high-risk strategy that requires extensive market knowledge and precise timing.
Mastering Implied Volatility Skew Trading: A Personal Journey to Optimizing Options Pricing Strategies
As an avid options trader, I’ve always been fascinated by the concept of implied volatility skew trading. The idea of exploiting differences in implied volatility (IV) to optimize options pricing strategies resonated with me. In this article, I’ll share my personal experience and practical insights on mastering IV skew trading.
Understanding Implied Volatility Skew
Implied volatility skew refers to the difference in IV between options with the same underlying asset but different strike prices or expiration dates. This skewness creates opportunities for traders to identify mispricings and capitalize on them.
| Option Strike | Implied Volatility |
| 100 | 20% |
| 105 | 22% |
| 110 | 25% |
| 115 | 28% |
In the above example, the IV increases as the strike price increases, indicating a positive skew. This means that options with higher strike prices are more expensive than those with lower strike prices, relative to the underlying asset’s current price.
Why IV Skew Matters
IV skew is crucial because it directly affects options pricing strategies. For instance, if you’re selling calls with a high IV, you may be overpaying for the option compared to a similar call with a lower IV. Conversely, buying puts with a low IV can be a lucrative strategy if the IV increases.
My Journey: Learning from Mistakes
I remember my early days as an options trader, when I would naively buy calls or puts without considering IV skew. I thought I was getting a good deal, but in reality, I was overpaying for options. It wasn’t until I suffered some significant losses that I realized the importance of IV skew.
Lesson 1: Don’t Ignore IV Skew
| Strategy | IV Skew | Outcome |
| Buying calls without considering IV skew | Positive skew | Losses |
| Selling puts without considering IV skew | Negative skew | Losses |
IV Skew Trading Strategies
Now that I’ve learned from my mistakes, I’ll share some IV skew trading strategies that I’ve found effective:
Strategy 1: Buying Low-IV Options, Selling High-IV Options
This strategy involves buying options with low IV and selling options with high IV. By exploiting the IV difference, you can create a profitable trade.
| Option | Implied Volatility | Trade |
| Buy put with 15% IV | 15% | Long |
| Sell put with 25% IV | 25% | Short |
Strategy 2: Ratio Spreads with IV Skew
Ratio spreads involve buying and selling options with different strike prices and IVs. By adjusting the ratio of options, you can create a trade that profits from IV skew.
| Option | Implied Volatility | Trade |
| Buy 1 call with 20% IV | 20% | Long |
| Sell 2 calls with 30% IV | 30% | Short |
Real-Life Example: Facebook (FB) Options
During Facebook’s Q3 2020 earnings season, I noticed a significant IV skew in its options. The IV of the $280 calls was around 40%, while the IV of the $300 calls was around 60%.
| Option | Implied Volatility | Trade |
| Buy call with $280 strike, 40% IV | 40% | Long |
| Sell call with $300 strike, 60% IV | 60% | Short |
By exploiting the IV skew, I was able to profit from the trade.
Frequently Asked Questions:
What is Implied Volatility Skew Trading?
Implied Volatility Skew Trading is a options trading strategy that takes advantage of the differences in implied volatility (IV) between different options contracts with the same underlying asset. IV is the market’s expected volatility of the underlying asset, and it is reflected in the option’s price. By analyzing the IV skew, traders can identify mispricings in the options market and optimize their options trading strategies.
What is Implied Volatility (IV)?
Implied Volatility (IV) is the market’s expected volatility of the underlying asset, as reflected in the option’s price. It is a measure of the market’s expectation of the underlying asset’s future price movements. IV is an important component of options pricing models, such as the Black-Scholes model.
What is the IV Skew?
The IV skew, also known as the volatility smile, is the graph of IV against strike price for a particular underlying asset. The IV skew is typically upward-sloping, meaning that options with higher strike prices have higher IVs. However, the IV skew can vary depending on market conditions and the underlying asset.
How does Implied Volatility Skew Trading work?
Implied Volatility Skew Trading involves identifying differences in IV between options contracts with the same underlying asset but different strike prices or expiration dates. Traders then use these differences to optimize their options trading strategies, such as buying and selling options with underpriced or overpriced IVs.
What are the benefits of Implied Volatility Skew Trading?
The benefits of Implied Volatility Skew Trading include:
* Increased profit potential: By identifying mispricings in the options market, traders can take advantage of profitable trading opportunities.
* Improved risk management: By adjusting options trading strategies based on IV differences, traders can manage risk more effectively.
