What Are Cboe® S&P 500 Equal Weight Index Options?

S&P 500 EWI options will be cash-settled and based on 1/10th the value of the S&P 500 EWI, the equal- weight version of the S&P 500 Index. The S&P 500 EWI includes the same constituents as the capitalization-weighted S&P 500 Index, but each constituent of the S&P 500 EWI is allocated a fixed weight of 0.2% of the index total at each quarterly rebalance.

The equal-weight design of the S&P 500 EWI aims to provide different exposure to the same constituents of the capitalization-weighted S&P 500 Index. For example, as of December 20, 2024, the bottom 400 constituents represented approximately 80% of the S&P 500 EWI, compared to just 26% in the S&P 500 Index.

S&P 500 EWI options may provide exposure to an index designed to be less impacted by a potential shift in concentration and momentum and aim to offer investors the ability to hedge against potential swings in the largest S&P 500 stocks. At launch, Cboe will list standard monthly options expiring on the third Friday (SPEQX) and weekly PM-settled options expiring every Friday (SPEQW), except for the third Friday. FLEX options will be offered on both SPEQX and SPEQW.

Both SPEQX and SPEQW options are planned to launch on April 14 and will be available during regular trading hours (RTH) between 9:30 a.m. ET and 4:15 p.m. ET.
