US Stocks Mixed as Meta Rises and Chip Shares Slip
In brief
US equities finished Monday mixed. The Dow Jones Industrial Average gained about 0.38% to 51,850.55 while the S&P 500 eased 0.06% to 7,807.24 and the Nasdaq Composite fell 0.44%. Meta climbed after its AI model launch; memory and chip stocks led the losers.
It was not a “risk-off” day so much as a rotation day. Energy, staples and communication services held up. Information technology and discretionary lagged. Salesforce helped the Dow after a double upgrade, rising about 2%. Meta Platforms jumped roughly 3.4% after unveiling Muse Wonder.
Semiconductors told the opposite story. The Philadelphia Semiconductor Index dropped more than 2.5%. Micron fell nearly 4% as traders weighed reports that China’s CXMT is advancing a new memory structure. Arm, SanDisk and Nvidia also lost ground. At a conference in Singapore, Broadcom’s Hock Tan said capital — not chips or power — is now the biggest constraint on AI buildout, a reminder that financing, not just supply chains, can cap the boom.
Oil firmed: West Texas Intermediate settled near $93.74 and Brent near $106.65 after violence around Saudi airports and doubts over a Russia–Ukraine energy truce. The US bond market was closed for Columbus Day, so the equity tape had less rate guidance than usual.
Bank earnings begin Tuesday. Goldman Sachs, according to TradingKey’s roundup, turned overweight on short-term global equities on the back of corporate profits. That call will be tested quickly if chip weakness spreads or Middle East risk premium keeps crude elevated.
For readers watching portfolios rather than politics, Monday’s message was narrow: AI software can still bid, hardware competition can still punish, and energy geopolitics still moves the commodity complex. Check official closing prints before you act — these figures are from market wrap reports and can be revised.
Readers comparing model cards should remember that vendor benchmarks are marketing documents until third parties replicate them. Price-per-token charts age quickly when competitors discount.
