Cboe Enables Electronic Auction for S&P 500 Index Options

Cboe Global Markets announced plans to enable its electronic auction mechanism to further serve market participants trading S&P 500 Index options (SPX) and S&P 500 Index Weeklys options (SPXW) on Cboe Options Exchange, beginning Monday, February 22. Striving to meet the growing demand from sophisticated retail investors seeking to trade smaller-sized orders, Cboe plans to activate its electronic crossing auction functionality, AIM (Automated Improvement Mechanism), for SPX and SPXW options during regular trading hours for trades up to a maximum size of 10 contracts. Cboe’s AIM auctions are currently enabled for trading in various other options classes and can be particularly valuable in providing participants with access to negotiated liquidity that is generally available in open-outcry trading. The auctions are expected to offer additional opportunities for price improvement throughout the trading day, leading to an opportunity for enhanced execution quality.
