CHINEXT INDEX EXTENDS GAINS TO RISE OVER 2%; LAB-GROWN DIAMONDS, PCB SECTORS LEAD RALLY

The Shanghai and Shenzhen stock exchanges, alongside Chinese regulators, have launched a scrutiny campaign into recent stock rallies driven by artificial intelligence optimism. Regulators have ordered several listed companies to clarify their actual business links to AI and ensure clear investor disclosure, while also asking ETF and fund managers with heavy AI exposure to justify their valuation methodologies and risk management plans. The regulatory clampdown follows a massive trading frenzy that pushed the tech-heavy Star 50 Index to a record high, lifting companies with little to no AI connection. State media has similarly warned against the "hidden risks" of inflated valuations and AI meme stocks, prompting more than 20 firms—including winemaker Wei Long Grape Wine Co.—to issue formal clarification statements to cool the retail-buying frenzy.
