The US stock market experienced a rebound on March 10, 2026, with the S&P 500 rising 0.59% to 6,835, despite intraday volatility driven by fluctuating oil prices. WTI crude oil prices swung dramatically, dropping over 16% to below $80 per barrel before surging back above $85, influenced by geopolitical developments involving Iran. This volatility impacted market sectors differently, with Basic Materials leading gains and Energy lagging. Semiconductor stocks, including Micron and Intel, saw significant gains, each rising over 5%, buoyed by strong performance in South Korea's tech sector. Micron's rise was further supported by easing inflation expectations due to lower oil prices, which also contributed to a weaker dollar. However, the market remains cautious, as the VIX index, a measure of market volatility, remains elevated at 22.85, indicating ongoing investor uncertainty.
