Semiconductors were the clear laggard, with the PHLX Semiconductor Sector Index (SOX) tumbling 3.43% as the AI trade remained under pressure following the resignation of Jensen Huang as CEO of Nvidia (NVDA). Among S&P 500 sectors, Information technology fell 1.70%, Industrials lost 0.42%, and Consumer Discretionary declined 0.45%. Investors instead favored more defensive groups, with consumer staples gaining 1.39%, energy rising 0.96% and financials advancing 0.80%. 

The 10-year Treasury yield climbed roughly 5 basis points to 5.15%, while the U.S. Dollar Index gained 0.20% to 103.38 as expectations for tighter Federal Reserve policy continued to support the dollar. The CBOE Volatility Index (VIX) rose more than 3% to 19.30, keeping volatility close to the important 20 threshold. WTI crude up slightly to about $89 per barrel, while gold was slightly lower near $3,880 an ounce. 

Inflation remained another concern. The Producer Price Index rose 0.3% in October from September, slightly below expectations, but wholesale prices were still 6.5% higher from a year earlier, the highest annual increase since November 2022. The combination of persistent inflation and a resilient economy continues to complicate expectations for Federal Reserve policy. See Inflation, Fed Hikes & the Fixed-Income Opportunity
