CMSC's stock price soared 5.04% during intraday trading on Tuesday, reflecting significant investor interest.

The surge follows the release of exceptionally strong preliminary first-quarter 2026 results by domestic memory chip giant ChangXin Technology, which reported revenue of RMB 50.8 billion and a net profit of RMB 33.012 billion. CMSC, through its investment arm CMSC Investment, was among the pre-IPO investors in ChangXin Technology, linking its performance to the chipmaker's success.

Investor optimism appears driven by CMSC's indirect exposure to ChangXin's robust profitability, which translates to nearly RMB 400 million in daily profit, potentially enhancing the value of CMSC's investment.
