Market Wrap US Stock Market Summary for March 26, 2026
Today at a Glance
Market Summary
On Thursday, March 26, the US stock market recorded steep declines as energy crisis concerns stemming from the prolonged Iran war coincided with a sharp selloff in the semiconductor sector. The S&P 500 closed down 1.74% at 6,477.16, while the Nasdaq plunged 2.38%, entering a correction phase. The Dow Jones also finished down 1.01% at 45,960.11. The Fear & Greed Index fell to 18, indicating an extreme fear state, and the VIX surged 12.16% to 28.41, underscoring that market anxiety had reached an extreme. As worries about a Strait of Hormuz blockade sent oil prices sharply higher, only the energy sector managed to climb, while uncertainty over AI memory demand following Google's TurboQuant algorithm announcement and a social media lawsuit ruling against Meta and Alphabet added selling pressure across the broader tech complex.
Sector & Asset Trends
The energy sector ($XLE, +1.57%) was the sole gainer of the day. With passage risks through the Strait of Hormuz escalating due to the Iran war, a situation in which roughly 20% of global oil supply was under threat persisted, and the crude oil ETF ($USO, +3.41%) reflected this with a strong advance. By contrast, the technology sector ($XLK, -3.11%) posted the largest decline, while communication services ($XLC, -2.36%) and industrials ($XLI, -2.32%) also fell sharply. Consumer discretionary ($XLY, -1.72%) was weak as well, but healthcare ($XLV, -0.34%) and consumer staples ($XLP, -0.45%) held up relatively well thanks to their defensive characteristics.
In the bond market, long-dated Treasuries ($TLT, -0.84%) and intermediate-term Treasuries ($IEF, -0.81%) declined in tandem, sustaining upward pressure on yields. As the surge in oil prices stoked inflation expectations, an unusual joint pullback in bonds and stocks emerged. Among commodities, gold ($GLD, -3.76%) and silver ($SLV, -6.81%) plunged sharply, drawing attention. Turkey's $8 billion gold drawdown is analyzed to have exerted downward pressure on the precious metals market. The semiconductor ETF ($SOXX) tumbled 4.75%, epitomizing weakness in the tech sector.
Key Stock Movements
Top Gainers: Energy stocks dominated the leaderboard. ConocoPhillips ($COP, +3.35%) posted the highest advance among the top 100 companies by market cap, followed by ExxonMobil ($XOM, +1.30%) and Chevron ($CVX, +1.29%). Among non-energy names, Salesforce ($CRM, +2.02%) rallied on robust cloud order momentum, while AbbVie ($ABBV, +1.90%) also rose on defensive healthcare demand. A unified defense signal from a Gulf coalition built a geopolitical risk premium across the energy sector.
Top Losers: Semiconductors controlled the bottom of the leaderboard. Lam Research ($LRCX, -9.35%) and Arista Networks ($ANET, -9.23%) posted the steepest declines, followed by Applied Materials ($AMAT, -8.34%). Meta ($META, -7.96%) plunged amid a social media addiction liability ruling combined with concerns over weakening AI memory demand following Google's TurboQuant AI algorithm announcement. Micron ($MU, -6.97%), Intel ($INTC, -6.53%), and TSMC ($TSM, -6.22%) likewise failed to escape the broad-based weakness.
Technical Signals & Outlook
RSI and stochastic readings show that most large-cap tech and growth names have entered oversold territory, while energy stocks are broadly overbought. Against the backdrop of an extreme fear phase reflected by the Fear & Greed Index at 18, the market carries the potential for sharp reversals depending on the trajectory of the Iran war and the situation around the Strait of Hormuz.
