Wall Street moved sharply lower on Tuesday as investors resumed selling semiconductor stocks, reversing much of the previous session's recovery. The Nasdaq Composite tumbled 3%, leading losses among the major indexes. The S&P 500 fell 1.7%, while the Dow Jones Industrial Average lost roughly 350 points, or 0.7%. The weakness was concentrated in the semiconductor sector, which has been at the center of the market's AI-driven rally over the past year. The iShares Semiconductor ETF dropped nearly 7%, giving back Monday's gains and extending the sharp correction that began last week. AI Leaders Continue to Face Pressure Several of the market's biggest AI beneficiaries remained under pressure. Micron Technology fell nearly 8% after surging 10% the previous session. The stock has experienced significant volatility after losing approximately 20% during a two-day selloff last week. Meanwhile, Broadcom declined 5% as investors continued to reassess growth expectations following its recent earnings report. The latest moves suggest investors are questioning whether valuations across the semiconductor industry have become stretched after a prolonged rally fueled by artificial intelligence enthusiasm. Despite ongoing optimism surrounding AI spending, traders appear increasingly cautious about paying premium valuations amid elevated interest rates and geopolitical uncertainty. Oil Prices Fall as Iran Deal Hopes Grow One bright spot for investors came from the energy market. WTI crude oil futures fell roughly 5%, slipping below $90 per barrel after comments suggesting shipping activity through the Strait of Hormuz is improving. President Donald Trump said a US-Iran agreement could potentially be reached within days and indicated that the key shipping route could reopen quickly if negotiations succeed. Lower oil prices helped ease concerns about inflation and provided support for consumer-focused and materials stocks. The housing sector also benefited from stronger-than-expected existing home sales data, helping offset some of the broader market weakness. Middle East Tensions Continue Despite optimism surrounding negotiations, geopolitical risks remain elevated. Iran has halted military strikes against Israel but warned it could resume military action if Israeli operations in Lebanon continue. Meanwhile, Israeli forces launched fresh strikes in southern Lebanon, including attacks near the historic city of Tyre. Israeli officials have signaled that military operations remain ongoing despite international efforts to reduce tensions. The conflicting signals highlight the fragile nature of the current ceasefire framework and explain why markets remain highly sensitive to developments in the region. Investors Focus on Major AI Catalysts Beyond geopolitics, investors are preparing for two major events that could influence market sentiment. Reports that OpenAI has confidentially filed for an IPO have added excitement around the AI sector. At the same time, the highly anticipated debut of SpaceX later this week is expected to become the largest IPO in market history. While some investors view these developments as evidence that the AI boom still has room to run, others worry that blockbuster public offerings have historically occurred near periods of peak market enthusiasm. For now, markets appear caught between two competing forces: strong long-term confidence in artificial intelligence and growing concerns that valuations have advanced faster than fundamentals. Tuesday's sharp decline suggests that investors remain willing to take profits while waiting for clearer signals on earnings, inflation, and the future path of interest rates.
