AI-Fueled Rally Powers S&P 500 to Fresh High as Tech Stocks Surge
The S&P 500 climbed 0.6% on Wednesday, October 8, 2025, propelled by a tech-sector rally driven by renewed Optimism around artificial intelligence. The Nasdaq Composite outperformed with a 1.1% gain, setting fresh closing highs as Federal Reserve meeting minutes signaled potential rate cuts later this year.
Advanced Micro Devices led the charge with a 12% surge after announcing its OpenAI partnership, while Dell Technologies jumped 9.1% on raised guidance. The AI boom contrasts with struggles in financial data services, where Fair Isaac tumbled amid price competition from Equifax.
