US Equity Market Resilience Amid Iran Conflict and Q1 Earnings Season - Share Dilution Risk

Live News

Against a backdrop of Brent crude trading above $100 per barrel and continued closures of the Strait of Hormuz, a chokepoint responsible for roughly 20% of global oil shipments, the S&P 500 and Nasdaq Composite notched all-time closing highs on Wednesday, extending a multi-week rally that has reversed the negative correlation between energy prices and equities observed in March. Since their recent troughs on March 30, the S&P 500 has gained more than 12% while the Nasdaq Composite has rallied 18%, with the two indexes up 4% and 9% respectively since the onset of the Iran conflict. The rally has been fueled by better-than-expected first-quarter earnings season results, a sharp rebound in technology and AI-related equities following an earlier 2024 valuation correction, and broad investor consensus that the ongoing energy price shock will be too short-lived to deliver a material hit to US economic growth. As of Wednesday morning, 20% of S&P 500 constituents have reported quarterly results, with 86% beating consensus earnings per share (EPS) estimates according to data from FactSet. While most strategists have noted fading investor sensitivity to Middle East volatility, a cohort of market participants has warned that equities may be underpricing risks associated with a prolonged regional conflict. --- US Equity Market Resilience Amid Iran Conflict and Q1 Earnings SeasonInvestors increasingly view data as a supplement to intuition rather than a replacement.

Key Highlights

Core market metrics and developments from the recent rally include the following: First, US equities have defied historical precedent by delivering positive returns amid a material energy supply shock, with the S&P 500 and Nasdaq up 4% and 9% respectively since the Iran conflict began, compared to average sell-offs of 5-7% during comparable past geopolitical energy disruptions. Second, earnings strength has served as the primary fundamental anchor for the rally: 86% of reporting S&P 500 firms have beaten consensus EPS estimates to date, with the technology sector projected to contribute 60% of full-year 2024 index earnings growth according to analysis from Strategas, leading all sectors in month-to-date performance. Third, analyst forward outlooks remain broadly constructive: Barclays raised its 2024 year-end S&P 500 price target to 7,650 from 7,400 on March 24, implying 7% upside from current closing levels, driven by robust tailwinds from AI capital expenditure and defense spending. Fourth, sentiment risks are rising: FOMO (fear of missing out) has amplified upward momentum, with the popular "buy the dip" trading strategy reinforced by past market-supportive policy and geopolitical interventions, leading some analysts to flag rising complacency around unpriced risks including extended supply chain disruptions, sustained inflationary pressure from elevated energy prices, and further geopolitical escalation in the Middle East. --- US Equity Market Resilience Amid Iran Conflict and Q1 Earnings SeasonSome investors focus on macroeconomic indicators alongside market data.

Expert Insights

The breakdown of the historical negative correlation between oil prices and US equities signals a meaningful shift in investor focus from short-term geopolitical volatility to medium-term fundamental drivers, particularly the durable earnings growth trajectory for US corporates supported by accelerating AI investment, resilient household consumption, and tight labor markets. Rick Gardner, Chief Investment Officer at RGA Investments, attributes the rally to three converging factors: easing near-term Iran conflict headlines, investor fatigue following elevated market volatility in March, and a stronger-than-expected start to the first-quarter earnings season. Venu Krishna, Head of US Equity Strategy at Barclays, notes that current oil price levels have not derailed broad earnings momentum, as the US economy's significantly reduced energy intensity compared to prior decades limits the pass-through of higher crude prices to household and corporate balance sheets, supporting the case for continued upside for US equities relative to global peers. However, a cohort of strategists has warned that the market's one-sided optimistic bias has left material downside risks unpriced. Kristina Hooper, Chief Market Strategist at Man Group, notes that markets have yet to fully price in tail risks including a prolonged closure of the Strait of Hormuz that could push Brent crude above $120 per barrel, triggering a rebound in headline inflation and forcing the Federal Reserve to delay planned interest rate cuts. The entrenched "buy the dip" mindset, reinforced by past market-supportive actions from the Trump administration including tariff easing and rapid de-escalation of geopolitical tensions, has created a false sense of security for many retail and institutional investors, per Hooper. Matt Maley, Chief Market Strategist at Miller Tabak + Co, adds that FOMO-driven momentum has pushed market participants to discount extended conflict risks, with no meaningful risk premium priced in for scenarios that could disrupt global supply chains and squeeze corporate margins. For market participants, the current environment calls for balanced positioning: while near-term momentum remains favorable, portfolios should account for both upside from continued earnings beats and downside from unpriced geopolitical risks, with a focus on high-quality sectors with durable earnings visibility as a hedge against elevated near-term volatility.
