Markets Plunge Then Rally Amid Energy and Defense Sector Turmoil

Markets experienced a dramatic intraday reversal on March 10, 2026, opening to sharp losses before staging a significant recovery. The S&P 500 dropped 3.2% in early trading, briefly touching a low that triggered circuit breakers, before recovering 2.4% by the close. The Nasdaq Composite mirrored the move, falling 3.4% before rebounding 2.3%, while the Dow Jones Industrial Average lost 2.9% before clawing back 2.1%. The volatility index, ^VIX, spiked to 38.7 — its highest level since mid-2024 — signaling heightened investor anxiety. The selloff was fueled by a sudden surge in crude oil prices, with the front-month West Texas Intermediate (CL=F) contract jumping 8.6% to $89.20 per barrel. This spike followed unconfirmed reports of supply disruptions in the Red Sea amid escalating regional tensions. Energy stocks reacted sharply: ExxonMobil (XOM) dropped 5.3%, and Chevron (CVX) fell 4.7%. Defense contractors were also hit, with Lockheed Martin (LMT) down 6.1% and Raytheon Technologies (RTX) off 5.8% as concerns mounted over potential military escalation. Despite the volatility, the rebound was led by tech and mega-cap stocks. Apple (AAPL) recovered from a 4.5% intraday loss to finish just 0.3% lower, aided by strong earnings guidance from its services division. The Nasdaq’s 2.3% recovery was also supported by a rally in semiconductor names, including Nvidia (NVDA), which rose 3.2% after a major data center deal was confirmed. The day’s swings reflect growing market sensitivity to geopolitical triggers and commodity volatility. With energy and defense sectors bearing the brunt of the shock, institutional traders adjusted positions rapidly, increasing options activity and hedging strategies. The rebound suggests resilience among large-cap equities, but the spike in volatility raises concerns about sustained market stability in the near term.
