September 22, U.S. stocks closed decisively higher as a surge in semiconductor shares reignited risk appetite. The Dow Jones Industrial Average rose 0.71%, the S&P 500 gained 1.49%, and the Nasdaq Composite vaulted 2.26%, easily outpacing the blue-chip benchmarks. Softer Treasury yields after a solid mid-week bond auction and fresh enthusiasm around artificial-intelligence hardware spending underpinned the advance, helping indexes shrug off lingering growth concerns.

AI hardware leaders dominated the leaderboard. ARM Holdings climbed 17.16% after unveiling new data-center designs, while the leveraged SOXL ETF rallied 14.77% on the sector’s momentum. Intel jumped 12.17% following upbeat foundry comments, Meta Platforms added 11.43% on expanded AI capex plans, and Advanced Micro Devices rose 9.95% on bullish server chip chatter. Marvell Technology advanced 5.38%, Nvidia gained 2.30% after hitting an early record, Tesla edged up 3.00% as analysts reiterated delivery forecasts, and Apple firmed 0.85% amid iPhone preorder strength. Declines were scant, with bear-side SOXS sinking 14.84%.

Broader tech and crypto names joined the rally. The TQQQ ETF soared 8.63%, Coinbase Global added 3.50% on higher bitcoin volumes, and Palantir Technologies improved 3.06% after winning a defense contract. VNET Group climbed 10.97%, while ARM-related supplier Broadcom rose 1.60%. On the flip side, Novo Nordisk fell 7.91% after weight-loss drug pricing scrutiny and SanDisk eased 1.41% in profit-taking.
