Wall Street posts best week since August despite Nvidia drag

Wall Street indexes posted their best week since August despite Friday losses, with Nvidia's continued decline dragging technology stocks and the Nasdaq down, overshadowing relief from softer US producer inflation data. The S&P 500 fell 0.40% to 7,561 and the Nasdaq dropped 0.91% to 25,136 on Friday, while the Dow Jones edged up 0.10% to 52,347. Nvidia shares fell over 2%, bringing weekly losses past 13% and erasing about $650 billion in market value amid leadership uncertainty following CEO Jensen Huang's departure. The Philadelphia Semiconductor index slid 3.7% as investors retreated from AI-related stocks. Nvidia faces regulatory probes over China export sales, with interim CEO Colette Kress set to address concerns in quarterly results due November 17. Softer producer price data reduced bets on aggressive Fed rate hikes, though a December increase is still expected.
