The Dow Jones Industrial Average experienced a significant downturn on Thursday, February 12, 2026, closing down 669.42 points, a 1.34% decline. The main driver of this sharp drop was a widespread sell-off in the technology sector, fueled by investor anxiety surrounding the long-term profitability of artificial intelligence investments. Despite some companies beating earnings expectations, broader concerns about future revenue and profit margins in the AI space led to a market-wide re-evaluation.
A prime example of this trend was Cisco Systems (CSCO), which plummeted 11.95% despite reporting quarterly profits and revenues that surpassed analysts' forecasts. The company's guidance on potentially tighter profit margins in the coming quarter, partly due to the increased costs of components for AI technologies, appeared to spook investors. This news had a ripple effect across the tech industry, contributing to the broader market decline. Other major tech-related losers on the Dow included IBM (IBM), which fell 5.05%, and Apple (AAPL), down 4.94%. The market sentiment was clearly focused on separating the perceived long-term winners from losers in the AI boom, leading to significant volatility.
In contrast to the struggling tech sector, several consumer staples and healthcare companies posted gains. Walmart (WMT) emerged as the top performer on the Dow, rising 3.33%. Other notable gainers included McDonald's (MCD), which climbed 2.27% after reporting strong quarterly profits, and healthcare giant Johnson & Johnson (JNJ), which saw a 1.46% increase. These gains suggest a flight to more defensive stocks as investors sought refuge from the uncertainty roiling the technology sector. The market's negative performance was also influenced by a report indicating a larger-than-expected slump in the sales of previously owned homes.
