Abstract: We assess the HSI and HSCEI index impact of CATL's 62.4m primary share placement across four review cycles to May 2027. HSI weight rises toward 0.8–0.9% at the Sep 2026 rebalance; HSCEI inclusion likely by Feb 2027 as post-placement shares dominate the MV12 window. Two passive flow events totalling 5.36m shares for HSI and HSCEI will happen over two implementation cycles.
