Summary by Relevant Sections Minimum Price Fluctuation Units - The minimum price fluctuation unit for stocks priced between HKD 10 and HKD 20 has been reduced from HKD 0.02 to HKD 0.01, and for stocks priced between HKD 20 and HKD 50, it has been reduced from HKD 0.05 to HKD 0.02 [1][11]. Benefits to the Market - The adjustments are expected to lower trading costs, improve transaction efficiency, and optimize price discovery, allowing trading prices to better reflect the actual value of stocks [6][14]. Implementation Timeline - The first phase of the adjustment took effect on August 4, 2023, with the second phase anticipated to be introduced around mid-2025, depending on the evaluation of the first phase's effectiveness [9][12]. Market Participant Feedback - The Hong Kong Stock Exchange received 110 responses from various market participants, with a majority supporting the two-phase reduction plan, believing it would lower trading costs and enhance market liquidity [8][11].

Future Considerations - The second phase will focus on stocks priced between HKD 0.5 and HKD 10, with a proposed 50% reduction in the minimum price fluctuation unit, while stocks priced below HKD 0.5 will not be adjusted at this time [11][14].
