Group 1 - Nasdaq plans to extend trading hours from 16 hours to 23 hours, potentially influencing other major exchanges to follow suit [1] - The Hong Kong Stock Exchange (HKEX) is considering a similar move to 24-hour trading, but its response has been ambiguous, stating it can be "considered" [1] - Current trading hours for HKEX are 5.5 hours, which is shorter compared to other major exchanges like NYSE (6.5 hours) and European exchanges (8.5 hours) [2] Group 2 - The average daily trading volume for HKEX is approximately HKD 250 billion, which has nearly doubled compared to the previous year, but is still low relative to A-shares, which average HKD 1.6 trillion in 4 hours [3] - The liquidity of the Hong Kong market is questioned, as many stocks experience no trading activity throughout the day, indicating that extending trading hours may not significantly benefit the market [3] - The potential for increased trading hours could exacerbate the existing time and information discrepancies between A-shares and HKEX, leading to concerns about market fairness [2][3]
