Cboe Advocates for Targeted Equity Market Structure Reform By Press Release - August 20, 2021 read the paper here. The paper outlines five key recommendations, highlighting current rules and regulations in the U.S. equities market that are outdated and need to be updated to fully align with modern markets: Modest Tick Size Reform – A more granular minimum increment should be established for a subset of national market system stocks in order to enhance and support price discovery and competition to the benefit of all investors. Enhance Best Execution – In connection with any tick size reform, the duty of best execution should be reviewed and potentially clarified in order to increase transparency and consistency for investors. Limit Order Protections – Limit order display requirements should be revisited to better reflect today’s stock prices, which enhance protection of investors’ limit orders, increase transparency and bolster price formation. Improve Execution Quality Reports – The publication of accessible and targeted execution quality information by broker-dealers should be pursued to further transparency and choice for investors. Shorten the Settlement Cycle – The settlement cycle should be shortened from T+2 to T+1. Source: Cboe Global Markets
