UNH delivered the best quarterly performance of the earnings season so far. The company raised its 2026 full-year adjusted EPS guidance from $17.75+ to $18.25+, signaling that prior medical-cost concerns were overblown. Watch for follow-through buying in managed care peers (HUM, MOH, CVS). The stock is up ~7% pre-market from $323.48 — this is today’s primary catalyst trade.

Halliburton reported first-quarter profit that more than doubled, crushing estimates for the energy services giant. With oil around $88.55 despite recent demand fears, the oilfield services sector is running ahead of commodity prices. Watch for sector rotation into XLE names on this print; key levels on HAL around the $28–32 range.

RTX reports Q1 2026 results pre-market. Defense spending remains a tailwind with the ongoing Iran conflict keeping geopolitical risk premium elevated. RTX’s Pratt & Whitney and Raytheon divisions have strong backlog visibility. Listen to the 8:30 AM call for guidance updates and Iran-related demand commentary.

GE Aerospace reported it is on track to hit the high end of its 2026 profit outlook — a rare and bullish guidance confirmation in the current uncertain macro environment. The aerospace/defense spend cycle is intact. Airlines remain a headwind for engine demand (see ALK), but commercial aviation recovery into summer travel season provides a near-term offset.

3M posted a rise in first-quarter profit, adding to the constructive tone from industrials this morning. The company is still in the midst of major restructuring (healthcare spinoff integration). A beat here confirms that industrial demand trends are holding up despite tariff headwinds.

Northrop Grumman posted higher first-quarter revenue, driven by continued defense budget momentum. With the US-Iran conflict sustaining elevated defense appropriations, NOC’s B-21 Raider and Ground Based Strategic Deterrent programs remain priority spending. Look for the stock to benefit from defense sector rotation alongside RTX.

Intuitive Surgical reports after the close — a key healthcare follow-on to the UNH setup. If UNH’s positive healthcare narrative holds through the session, ISRG could gap up tomorrow. Watch procedure volume trends and da Vinci placements, which are the primary growth drivers in the robotic-assisted surgery market.

Trump’s nominee to replace Jerome Powell faces the Senate Banking Committee in what Bloomberg describes as potentially “one of the most contentious” such hearings in decades. Markets will parse every word on three themes: (1) Fed independence — Warsh has signaled alignment with Trump’s rate-cut push; (2) Balance sheet reduction — he supports QT to fight inflation; (3) the DOJ investigation into the Fed’s building renovation. Treasury yields and the dollar could move sharply on hawkish or dovish surprises. Warsh comments are a live intraday risk for the 10:00 AM time slot.

The two-week ceasefire between the US and Iran expires tomorrow. Trump has signaled he is unlikely to extend it; Tehran has not confirmed participation in new talks. Three vessels attempted to transit the Strait of Hormuz overnight. Any breakdown in negotiations will immediately spike oil prices (WTI currently $88.55, suppressed by peace-talk hopes) and send defense stocks even higher. Keep this as a background risk all session — a breaking-news spike could come at any time.

Apple confirmed Monday that Tim Cook steps down September 1 as CEO, becoming Executive Chairman, with hardware chief John Ternus taking over. Market reaction has been muted (AAPL <−1% pre-market), suggesting investors view this as a planned transition. Ternus will face an immediate challenge: fixing Apple’s AI strategy, competing in the autonomous vehicle space, and managing the company’s complex supply chain in an elevated-tariff environment.

RTX (conference call 8:30 AM ET), GE Aerospace, HAL, MMM, NOC, and UNH all report before the open. This is one of the heaviest BMO earnings slates of the Q1 cycle. The cumulative effect on the indices will be a strong upward drift in industrials (XLI) and healthcare (XLV) at the open. Watch for sector rotation out of tech and into these reportees on any pop — the regime supports adding long exposure on opening breakouts.

The US-Iran conflict has created a sustained defense spending supercycle. With the ceasefire expiring tomorrow and Trump signaling no extension, the defense premium in stocks like RTX, NOC, GE, and LMT is structural, not mean-reverting. Elevated oil prices (WTI $88+) amplify the energy services angle (HAL, SLB). Watch for any breakthrough in peace talks as the primary risk to this theme — a deal could trigger a sharp reversal in defense names.

UnitedHealth’s blowout Q1 beat signals the managed care complex is recovering from its 2025 medical-cost crisis. With UNH up ~7%, sector peers HUM, MOH, CVS, and ELV are likely to gap sympathy. JPMorgan’s S&P 500 earnings target raise and the “blue sky” 8,000 scenario both hinge on healthcare contributing positively to the earnings trajectory — today’s UNH print is the first validation of that thesis in a year.

Kevin Warsh’s Senate confirmation hearing at 10 AM ET could be the most important macro event of the week. Treasury Secretary Bessent is calling for rate cuts; Warsh has aligned with that view but must navigate hawkish inflation data (CPI 3.3% YoY). Any dovish signals from Warsh could rally rate-sensitive sectors (XLU, XLRE, XLF banks). The April 28–29 FOMC meeting is in eight days — this hearing sets the tone for that decision. Positioning ahead of FOMC creates entry opportunities in rate-sensitive names on any Warsh-driven selloff today.
