In recent years, correlation and relative value trading have maintained a strong foothold, delivering consistent profitability for many traders. As the global economy recovers from the pandemic, with businesses emerging at varying paces, this trend shows no signs of waning. 

Understanding Dispersion and Correlation Skew Trades 

Dispersion and correlation skew trades exploit the relative mispricing between implied correlations derived from the implied volatilities of index options and those of the index components. Essentially, these strategies typically involve selling the implied volatility of the index, which often contains a risk premium, and buying the implied volatility of the individual components. This approach capitalizes on the potential for idiosyncratic shocks in individual stocks, which can be monetized through Gamma hedging. 

For instance, an index may reflect a generalized market sentiment, embedding a risk premium due to broader market uncertainties. Meanwhile, individual stocks within the index can exhibit unique, company-specific events that cause their implied volatilities to diverge from the index. By capturing these discrepancies, traders can achieve significant gains. 

Crucial Data Points for Effective Strategy Implementation 

Successful modeling and back-testing of these strategies require detailed and high-quality data. Key data points include: 

• At-the-money (ATM) implied volatilities of both the index and its individual constituents. This provides a baseline for understanding the general volatility environment. 

• Implied volatilities at various skew points (e.g., 10, 25, 35, 65 Delta). These points help in assessing the market’s expectations of volatility across different strike prices, offering insights into potential mispricings. 

• Strikes and Greeks (Delta, Theta, Vega). Greeks are essential for managing the risk and potential reward of options positions, providing a nuanced understanding of how different factors influence option prices. 

• Index and stock prices. Accurate and timely price data is crucial for evaluating the performance of trading strategies and making real-time decisions. 

These data points can be collected at both end-of-day and intraday frequencies, providing a robust foundation for analysis. Intraday data, in particular, allows for more precise modeling and real-time strategy adjustments, which can be critical in fast-moving markets.
