Core Viewpoint - Hong Kong Stock Exchange (HKEX) is consulting on proposals to optimize the trading unit framework to enhance trading, settlement, and clearing efficiency, with a consultation period lasting 12 weeks until March 12, 2026 [1][2]. Group 1: Proposed Changes - The current trading unit system, which has over 40 different trading units, will be simplified to 8 standard options: 1 share, 50 shares, 100 shares, 500 shares, 1000 shares, 2000 shares, 5000 shares, and 10000 shares [2][3]. - The lower limit for the value of each trading unit will be reduced from 2000 HKD to 1000 HKD, while an upper limit of 50000 HKD will be introduced for units greater than 100 shares [4][5]. Group 2: Market Impact - Approximately 25% of issuers may need to adjust their trading unit sizes due to the proposed changes [3]. - The new framework aims to lower the entry barriers for retail investors, thereby increasing participation in the Hong Kong stock market [1][4]. Group 3: Implementation Phases - The implementation will occur in phases, with new issuers required to select standardized trading units and comply with the revised value guidelines upon listing [5][6]. - Existing issuers will transition to the new framework within a specified timeframe after the implementation of a paperless securities market [6]. Group 4: Future Considerations - HKEX is also exploring ways to optimize the fractional share trading mechanism to further enhance trading efficiency following the changes to the trading unit framework [6].
