[The Shenzhen Stock Exchange revised the GEM index preparation plan to take effect when the regular adjustment is made on December 14, 2026] On November 6, in order to further improve the index preparation method, the Shenzhen Stock Exchange and Shenzhen Securities Information Co., Ltd. decided to revise the GEM index preparation plan and gradually adjust the upper limit of the weight of a single sample stock to 15%. The adjustment method is as follows: During each periodic adjustment period, if the actual weight of the largest sample stock exceeds 14.5% when the periodic adjustment is approaching, 0.5% will be added to its actual weight and then rounded up, which will be used as the adjusted upper limit of the weight of a single sample stock. During the adjustment period, the weight upper limit and weight adjustment factor will only be adjusted downward, not upward, until the actual weight of the largest sample stock does not exceed 14.5%, achieving the goal of the weight upper limit of 15%. This revision will take effect on December 14, 2026 when the periodic adjustment is made.
