[The series of adjustments to the Hang Seng Index continue to advance, and the expansion of the Hang Seng Technology Index reaches a key node this week] September 16th, the Hong Kong stock market ushered in two important nodes for index adjustment on September 15: Xiyin-W was officially included in the Hang Seng Composite Index and its sub-indices, and the Hang Seng Technology Index compilation reform consultation period entered the final countdown. From the rapid inclusion of individual stocks into the mechanism to the systematic reshaping of the flagship index, the Hang Seng Index series is undergoing a round of intensive rule adjustments. Analysts believe that Xiyin-W’s inclusion in the Hang Seng Composite Index is expected to bring about related capital allocation needs and improve stock liquidity. At the same time, if the Hang Seng Technology Index is expanded to 50 stocks according to the consultation plan and a dual-track stock selection mechanism of "market value + income growth" is introduced, the landscape of the Hong Kong stock technology index may be rewritten.
