ChiNext and STAR 50 fall over 3% as tech shares lead China selloff

The divergence matters more than the headline drop: growth-heavy boards fell far harder than the Shanghai Composite, pointing to a concentrated unwind in computing hardware, chips and software rather than broad risk-off. The breadth figure — over 4,400 decliners across all three exchanges — suggests selling pressure was wide even as the index-level damage clustered in tech. Whether that concentration persists, or spreads into the broader market, is the open question worth watching.
