<h1>Asian stocks rise on Fed speech anticipation and tariff inflation worries, spotlighting tech concentration and regulatory scrutiny</h1> Asian equities were broadly higher after a mixed US session, with market movements driven by anticipation of central bank commentary at a policy symposium and concern over potential tariff-driven inflation from the US administration. The Fed chair's upcoming remarks and weak US jobs data are key macro drivers. Major tech and AI-focused stocks pared earlier losses, highlighting concentration risk and valuation concerns in that sector. Manufacturing PMIs showing contraction in parts of Asia and tariff exposure to US markets pose trade and economic risk. Market volatility and sector concentration may raise regulatory and disclosure scrutiny for issuers and investors.
