US Equities Hit Record Highs as Investors Pivot from Middle East Conflict to Earnings Growth

US stock indices are demonstrating remarkable resilience, hitting record peaks even as geopolitical tensions with Iran escalate and critical energy shipping lanes remain blocked. The S&P 500 and Nasdaq Composite resumed their rally on Wednesday, signaling a stark shift in investor psychology compared to previous months when rising energy costs typically triggered market sell-offs. Since their recent lows on March 30, the S&P 500 and Nasdaq have surged more than 12% and 18%, respectively. Since the onset of the conflict, the S&P 500 has gained nearly 4%, while the Nasdaq has climbed nearly 9%. Market participants are increasingly betting that the current oil shock will be transient and insufficient to derail broader economic expansion. Corporate profitability remains the primary catalyst for this ascent. According to FactSet, 86% of S&P 500 companies that have reported quarterly results so far have beaten earnings per share expectations. The technology sector has emerged as the strongest performer this month, with analysts at Strategas estimating that tech will account for 60% of total earnings growth this year. Some strategists are raising their outlooks; Barclays' Venu Krishna increased his year-end target for the S&P 500 to 7,650, citing extremely strong momentum in AI and defense spending. However, a minority of analysts warn that the market may be overly complacent, failing to fully price in the long-term inflationary risks and supply chain disruptions associated with a prolonged conflict in the Middle East.
