样本选取方面，样本空间同中证全指指数的样本空间，可投资性筛选过去一年日均成交金额排名位于样本空间前 90%。对于样本空间内符合可投资性筛选条件的证券，计算所属中证四级行业海外收入占比，按照从大到小排序，剔除排名后 50%或海外收入占比连续两年下降的行业，将剩余中证四级行业内的上市公司证券作为待选样本。The csi industrial competitive advantage index selects 50 listed company securities with relatively large scale, good profitability, and strong business competitiveness as index samples to reflect the overall performance of listed company securities with strong industrial competitive advantages.
According to the Securities Times APP, China Securities Index Co., Ltd. announced that the csi industrial competitive advantage index will be officially launched on November 7, 2024, providing the market with a more diverse investment target.
The csi industrial competitive advantage index selects 50 listed company securities with relatively large scale, good profitability, and strong business competitiveness as index samples to reflect the overall performance of listed company securities with strong industrial competitive advantages. Index samples include zoomlion (000157.SZ), xcmg construction machinery (000425.SZ), guangzhou lingnan group holdings (000524.SZ), china nonferrous metal industry's foreign engineering and construction (000758.SZ) and other symbols.
In terms of sample selection, the sample space is the same as the csi all share index sample space, with investable screening based on the top 90% of daily average trading volume over the past year in the sample space. For securities within the sample space that meet the investable screening criteria, calculate the proportion of overseas income in the relevant csi level four industry, sort from largest to smallest, exclude the bottom 50% or industries with a continuous two-year decline in overseas income proportion, and consider the remaining listed company securities in the relevant csi level four industries as candidate samples.
