US stock indices remained volatile on Monday afternoon as a sharp retreat in Treasury yields failed to sustain a broad based equity rally following dovish remarks from Federal Reserve Chair Jerome Powell. While the Dow added 0.4% the S&P 500 and Nasdaq Composite dipped 0.1% and 0.4% respectively as heavy losses in the semiconductor sector offset gains in financials and utilities. Powell signaled that the central bank intends to look through the current energy price shock with West Texas Intermediate futures surging amid persistent threats to Red Sea exports and Iranian infrastructure. Although the 10-year Treasury yield tumbled, chipmakers like Micron and Lam Research sank over 5% as investors pivoted toward energy and utility giants reaching all time highs. Despite President Trump's report of serious discussions in Iran the CBOE Volatility Index remained elevated as markets weigh resilient corporate earnings against the risk of an energy infrastructure meltdown.
