Dow Jones Tumbles Amid AI Profitability Concerns

The Dow Jones Industrial Average fell 669.42 points (1.34%) on Thursday, Feb. 12, 2026, driven by a broad technology-sector sell-off as investors questioned long-term profitability of AI investments. Cisco plunged 11.95% despite beating quarterly estimates after warning of tighter margins from higher AI component costs, while defensive names such as Walmart, McDonald's and Johnson & Johnson rose amid a flight to safety and weaker existing-home sales data.
