优化创业板指数方案。 为进一步优化完善指数编制方法，提升指数可投资性，深圳证券交易所及其子公司深圳证券信息公司于2025年4 月30日发布公告，修订创业板指数编制方案，并将于2025年6月16日正式实施。 创业板指数编制方案修订内容包括： 一是引入ESG负面剔除机制，剔除国证ESG评级在B级以下的股票，降低指数样本发生重大风险事件概率； 二是引入个股权重上限机制，通过设置权重调整因子，使单只样本股权重在每次定期调整时不超过20%，将 单只样本股对指数的影响控制在合理范围内。 经评估，优化措施实施后不会造成指数样本股及权重大幅调整，不改变指数运行特征，对指数样本股和跟踪产 品运作不产生影响。 资料显示，创业板指数发布于2010年6月1日，选取总市值大、流动性好的100只创业板股票作为样本，是A股市 场重要标尺指数之一，也是中国创新创业企业的代表性指数，产品丰富、交易活跃、关注度高。深交所表示， 本次修订充分听取市场意见建议，充分吸收借鉴近年来宽基指数编制创新理念，进一步提升指数表征作用和投 资功能，更好满足各类投资者的资金配置需求。 近年来，深交所在中国证监会统一领导下，不断加快投资端建设，持续提升中长期资金服 ...
