US equities post weekly losses; S&P 500 -0.8%, Dow -1.6%

US major indices closed the week lower despite a Friday rebound, with the S&P 500 down 0.8%, Nasdaq -0.7%, and Dow -1.6%. The decline suggests persistent risk-off sentiment, though the rebound indicates some dip-buying. The move is consistent with recent market volatility, but the magnitude of the Dow's underperformance may signal sector rotation.
