UNITED STATES: CBOE Expands Implied Correlation Index Suite, Adds Eight Additional Volatility-Related Indices

Tuesday July 19 2022

Cboe Global Markets, Inc. (Cboe: CBOE) has announced the expansion of its Cboe Implied Correlation® Index suite with the recent addition of eight new indices. Market participants can now access a full suite of volatility-related indices across a range of maturities and skews to help gain a more complete view of the potential factors driving volatility in the equity markets. 

The Cboe Implied Correlation Indices are the first widely disseminated market estimates of the average correlation of the stocks that comprise the S&P 500® Index (SPX). The benchmark indices are designed to offer insight into the relative cost of SPX options compared to the price of options on individual stocks that comprise the SPX, and help market participants to identify the potential drivers of implied volatility for the SPX and evaluate the potential implications of major macroeconomic events on market expectations. 

Generally, market participants use correlation as a risk management tool to set systematic risk exposure levels and maximize risk diversification benefits. Because correlation is essentially a statistical measure of diversification, market participants typically closely monitor correlation levels to help ensure their risk exposures line up with their risk appetite levels and to develop risk transfer strategies.  

The eight new indices complement Cboe’s existing three-month Implied Correlation Index (COR3M), which it began publishing in July 2021. Similar to COR3M, the new indices utilize Cboe’s innovative, proprietary methodology to calculate implied correlation. With these new offerings, Cboe offers a complete suite of indices that provides maturity representation of implied correlation for SPX for one-, three-, six-, nine- and 12-month tenors, and across different skews: 

• Tenor Indices (tickers: COR1M, COR3M, COR6M, COR9M, COR1Y), which are calculated using 50 delta implied volatilities and show market expectations of correlation risk over time 
• Delta Skew Indices (tickers: COR10D, COR30D, COR3MD, COR70D, COR90D), which are calculated using three-month implied volatilities and signify market expectations of correlation during different delta shock scenarios 

Cboe is publishing intraday values for Cboe Implied Correlation Indices on its Cboe Global Indices Feed and disseminating index values four times per minute throughout the trading day. Index values are also available through Bloomberg and Refinitiv.
