The Methodology of SSE 180 Index Will Be Amended
In order to improve index representativeness and investability, Shanghai Stock Exchange and China Securities Index Co., Ltd decide to amend the index methodology of SSE 180 Index. The details are as following: (1) newly add liquidity criteria “securities ranked in the top 90% in the index universe in terms of average daily trading value over the past year in descending order are eligible for inclusion”; (2) the selection method will be changed to select the largest 180 securities with ESG ratings higher than C in terms of average daily total market capitalization of over the past year as constituents; (3) newly add the weighting constraints “the weight of the constituent is capped at 10%, the total weight of top 5 constituents is capped at 40%, and the total weight of constituents in each sector is the same portion in terms of free-float market capitalization as the corresponding sector in the universe”. (4) delete the fast entry rule in ongoing review. The rest part of index methodology will remain unchanged.
The amended index methodology of SSE 180 Index will be implemented on Dec 16, 2024. Regarding the amended methodology, please refer to the official website of Shanghai Stock Exchange (www.sse.com.cn) and CSI (www.csindex.com.cn).
