Markets Shrug Off Iran Tensions; Tech Leads Recovery
Market Overview
US stock indexes closed mixed on April 13, 2026, after erasing early losses triggered by geopolitical tensions and weak housing data. The S&P 500 (SPY) rose +0.09%, while the Dow Jones (DIA) fell -0.39% and the Nasdaq 100 (QQQ) gained +0.16%. June E-mini S&P futures (ESM26) and Nasdaq futures (NQM26) pointed to steady open, up +0.12% and +0.20% respectively, signaling some momentum into the week as earnings season officially kicks off with money center bank reports.
The market's recovery hinged entirely on a sharp rally in software equities, led by Oracle Corporation (ORCL), which surged +8% after announcing new AI-driven utilities industry software aimed at cutting operational costs. That strength cascaded across enterprise software, with ServiceNow (+5%), Workday (+5%), Atlassian (+4%), and Cadence Design Systems (+4%) all posting significant gains. This sector rotation provided critical upside offset against early-session selling pressure tied to crude oil volatility and disappointing real estate data.
Geopolitical Risk & Energy Markets
President Trump's announced naval blockade of the Strait of Hormuz—following stalled US-Iran peace negotiations over the weekend—sent crude oil prices into sharp rally territory. WTI crude (CLK26) climbed more than +5% to +7% intraday on the news, reflecting the geopolitical premium attached to one of the world's most critical chokepoints.
The strait's strategic importance cannot be overstated: approximately one-fifth of global oil and liquefied natural gas transits through the corridor daily. Iran, which has managed to export around 1.7 million barrels per day (bpd) throughout regional conflict, issued a retaliatory threat: any blockade of Iranian shipping hubs would trigger Iranian targeting of "all ports in and close to the Persian Gulf." This tit-for-tat escalation raised the probability of sustained supply disruption and underscored the downside risk to global energy availability in Q2 2026.
The oil price surge immediately pressured energy-sensitive equities, particularly airlines and cruise operators. United Airlines Holdings (UAL) fell -2%+, Delta Air Lines (DAL) lost -2%+, Southwest Airlines (LUV) declined -2%+, and Norwegian Cruise Line Holdings (NCLH) dropped -2%+. Carnival Corporation (CCL) posted the steepest loss at -3%+, as elevated fuel costs directly compress margins in an already margin-constrained travel sector. American Airlines Group (AAL) and Alaska Air Group (ALK) fell -1%+ on the same logic.
Housing Data & Fed Policy Implications
A separate headwind arrived via March existing home sales, which contracted -3.6% month-over-month to 3.98 million units annualized—a 9-month low and below consensus expectations of 4.05 million. This dovish datapoint for monetary policy supported a temporary bid in duration assets (treasuries), but the crude oil inflation scare ultimately dominated bond market sentiment.
The 10-year Treasury note yield (ZNM6) rose +4 basis points to 4.321% despite the weak housing print. The 10-year breakeven inflation rate hit a 3-week high of 2.403%, reflecting market expectations that the Strait of Hormuz blockade could materially tighten global energy supply. Meanwhile, the Fed funds futures market is pricing in only a 2% probability of a +25 bp rate hike at the April 28–29 FOMC meeting, suggesting traders view the housing weakness as a sufficient counter to oil-driven inflation concerns.
Overseas, the 10-year German bund yield rose +2.4 bp to 3.082%, and the 10-year UK gilt yield climbed +2.5 bp to 4.861%, as European inflation expectations also ticked upward. The ECB futures market is discounting a 40% probability of a +25 bp rate hike at the ECB's April 30 policy meeting, reflecting similar oil-driven inflation angst in the eurozone.
Earnings Season Kicks Off; Tech Outperformance Continues
First-quarter earnings season began in earnest on April 13, with a slate of major money center banks reporting results. Goldman Sachs Group (GS) disappointed, declining -3%+, after reporting Q1 FICC (Fixed Income, Currencies, and Commodities) sales and trading revenue of \(4.01 billion**, materially below the consensus estimate of **\)4.87 billion. This weakness underscored ongoing headwinds in fixed-income markets and trading desks' ability to generate revenue during a period of lower yield volatility.
Consensus earnings expectations for Q1 2026 suggest S&P 500 earnings growth of +12% year-over-year, according to Bloomberg Intelligence. However, stripping out the technology sector reveals a starkly different picture: earnings growth of only ~3%, marking the weakest showing in two years for the broad market ex-tech. This divergence underscores the continued concentration of earnings growth within large-cap software, semiconductors, and AI infrastructure plays.
Notable biotech gainers provided positive sentiment elsewhere:
- Revolution Medicines (RVMD) surged +35% after its pancreatic cancer treatment demonstrated improved patient survival in late-stage trials.
- Ideaya Biosciences (IDYA) jumped +14% after a mid-late stage trial of its experimental eye cancer therapy met its primary endpoint.
Stock-Specific Movers
SanDisk Corporation (SNDK) advanced +6% after Nasdaq announced the company will replace Atlassian (TEAM) in the Nasdaq-100 Index effective Monday, April 20. This index inclusion signals confidence in SanDisk's competitive positioning in flash memory and storage solutions.
Palantir Technologies (PLTR) gained +4% after President Trump publicly praised the company's "proven war-fighting capabilities and equipment," lending political tailwind to defense and intelligence software applications.
ON Semiconductor Corporation (ON) rose +2% after Bank of America Global Research upgraded the stock to Buy from Neutral with a $85 price target, reflecting improved semiconductor cycle and AI infrastructure demand.
On the downside, Conagra Brands (CAG) tumbled -5%+ to lead S&P 500 losers after announcing the replacement of CEO Sean Connolly with John Brase effective end of May—a leadership transition that sparked investor concern. Fastenal Company (FAST) fell -4%+ to lead Nasdaq-100 losers after reporting Q1 operating income of $447.6 million, below consensus of $449.3 million. Best Buy (BBY) declined -3%+ after Goldman Sachs double-downgraded the stock to Sell from Buy with a $59 price target, citing consumer discretionary weakness. Hewlett Packard Enterprise (HPE) lost -2%+ after Raymond James downgraded the stock to Outperform from Strong Buy.
Software names mostly recovered, though Intuit (INTU), Datadog (DDOG), and Adobe (ADBE) each declined -2%+, suggesting some profit-taking in high-flyers after recent weakness.
