United States: Daily Stock Market Performance Insight - February 18, 2026

U.S. equity markets showed resilience as indices finished mostly higher. The S&P 500 edged up 0.1 percent to 6,843.22 on Tuesday and rose further by 0.6 percent on Wednesday, spearheaded by Nvidia. The Nasdaq Composite gained 0.1 percent to reach 22,578.38, while the Dow Jones Industrial Average slipped 0.1 percent to 49,533.19. Trading activity was subdued with 17.76 billion shares changing hands, falling short of the 20-session average of 20.70 billion. Market volatility cooled as the CBOE Volatility Index dropped 4.3 percent to 20.29. Tech leadership was a primary driver, with the Nasdaq benefiting from a 2.48 percent jump in Nvidia and a 2.61 percent rise in Amazon. Microsoft and Apple also advanced 1.12 percent and 0.62 percent respectively. These moves are significant as the top five tech stocks now represent over 40 percent of the Nasdaq weighting. While the Nasdaq 100 is down 3.3 percent for February, a reported deal between Nvidia and Meta Platforms has helped wane AI disruption fears. Defensive sectors also outperformed, with Utilities rising 2.8 percent and Real Estate advancing 1.5 percent. This rotation aligns with year-to-date trends where the S&P 500 Value Index has gained 3.5 percent while the Growth Index has fallen 3.5 percent. On the economic front, December durable goods orders fell 1.4 percent, outperforming the expected 2.0 percent drop. Housing data remained a bright spot with 1.404 million starts and 1.448 million permits both beating estimates. Mortgage rates declined to 6.17 percent, driving total applications up 2.8 percent. Investors should remain cautious as geopolitical risks escalate with stalling peace talks and military drills in the Strait of Hormuz. Watch for the upcoming Fed minutes to confirm rate cut timing, as ten-year Treasury yields currently hover at 4.06 percent. Individual stock moves like Krystal Biotech rising 4.1 percent following an earnings beat demonstrate that fundamental performance still attracts capital.
