U.S. stocks are trading lower at midday Feb. 17, 2026, as artificial intelligence (AI) jitters weigh on tech giants, pulling down the Nasdaq and S&P 500 while the Dow shows relative resilience.
S&P 500 Tests Support as AI Volatility Pressures Wall StreetThe Nasdaq enters today’s session following five consecutive negative weeks, a stretch not seen since 2022. The S&P 500 now tests its 100-day moving average, with the 6,850 level acting as an immediate technical battleground. If buyers fail to defend that zone, traders anticipate additional near-term pressure on equities.
Sector action confirms a defensive rotation. Utilities advanced, building on last week’s 1.5% gain, while technology and communication services lag. Investors appear to favor predictable cash flows over ambitious capital expenditure tied to AI infrastructure.
The holiday-shortened week features several potential catalysts. Investors watch the Empire State Manufacturing Index, Federal Open Market Committee (FOMC) minutes, fourth-quarter GDP estimates, and the PCE price index. Earnings from Palo Alto Networks, Toll Brothers, and Walmart are also commanding attention.
For now, the Dow’s relative resilience provides a subtle counterpoint to tech’s softness. Beneath the headline declines, sector rotation continues to reshape leadership. Wall Street trades cautiously on Tuesday afternoon, balancing innovation-driven optimism with valuation discipline in real time.
