China semiconductor chip stocks pull back; STMicroelectronics’ StarPower falls over 10%

The breadth of the selloff — more than a dozen names down sharply rather than one outlier — points to a sector-wide repricing of domestic chip exposure rather than company-specific news. StarPower's double-digit decline stands out as the session's clearest signal of how quickly positioning can unwind in a crowded theme. For a market that has leaned heavily on semiconductor self-sufficiency as an investment narrative, this kind of synchronized drawdown matters more than any single name. Whether the pullback stays contained to the most crowded listings or spreads across the broader supply chain is the open question worth tracking.
