"Arm Stock Plummets as AI Hype Wanes"

Arm Holdings' stock suffered its worst day on record, plummeting over 19% in Tuesday trading, following a period of explosive gains driven by the company's positive financial results and the growing interest in artificial intelligence. Despite the recent surge, the stock's valuation appeared to be getting ignored, leading to its sharp decline as the broader market and tech stocks also weakened. Arm's market capitalization closed just above $123 billion, putting it on par with major companies like Boeing, Goldman Sachs, UPS, and AT&T.
