Today (15th) constituent changes for multiple A-share indices took effect,
including the Shenzhen Composite Index, ChiNext Index, SSE 50, SSE 180, CSI 300,
CSI 500, STAR 50 and STAR 100. Index compilers updated and replaced constituents
stocks per standard rules; the reconstitutions are notable for a concentrated
inclusion of hard‑tech/deep‑technology names.
