<h1>Regional equity pullback after Fed chair warns stocks overvalued, sparking volatility and risk-management concerns for investors</h1> Regional equity markets mostly declined after a pause in U.S. gains following remarks by the central bank chair warning that equities are highly valued, prompting renewed market volatility and investor concern about inflation and employment trade-offs. Major indices pulled back after multi-day record highs; a leading chip maker and several large technology firms retraced gains, contributing to index declines. Treasury yields eased slightly while oil and currency moves were modest. The developments underscore heightened market risk from monetary policy shifts and could affect disclosure, fiduciary duties, and risk-management obligations for market participants.
