Stocks rose Friday on renewed hopes for an Iran peace deal. The S&P 500 Equal Weight and the Dow Jones Industrial Average both hit fresh all-time highs heading into the Memorial Day weekend. And somewhere in that rally, defense names gave back ground.
That’s the trade people keep getting wrong.
Defense stocks are not a war trade. They never really were. The ceasefire rumor reflex — sell LMT, trim RTX, rotate into energy — is a short-term reaction to a structural story that plays out over years, not news cycles. The distinction matters for how you size positions and when you actually add versus when you’re just chasing a headline.
What the Backlog Data Actually Tells You
When U.S. and Israeli forces launched strikes on Iran on March 1, 2026, the initial defense surge was textbook. Northrop Grumman (NOC) jumped roughly 6%. RTX surged approximately 4.7%. Lockheed Martin (LMT) gained roughly 2.8%. The iShares U.S. Aerospace and Defense ETF (ITA) surged 14% in 2026, with the rally accelerating following the outbreak of hostilities.
Since then, however, defense stocks have leveled out — and some have pulled back sharply. That’s the part institutional traders understand better than retail: the initial pop is not the investment thesis. The spending cycle that follows is.
Northrop Grumman sits on a record $95.7 billion backlog, led by the B-21 Bomber and the Sentinel ICBM program. Sentinel alone is estimated near $141 billion across decades. Those programs do not depend on whether Iran accepts a ceasefire proposal this week. Lockheed Martin entered 2026 with a $194 billion backlog and is projecting $77.5 to $80 billion in full-year revenue. The fiscal 2026 National Defense Authorization Act proposes $924.7 billion in U.S. military spending, with supplemental appropriations for Operation Epic Fury potentially pushing total federal defense expenditure toward $1.2 trillion for the fiscal year.
General Dynamics’ Marine Systems segment posted 21% revenue growth to $4.34 billion in Q1 2026, driven by Arleigh Burke destroyer production. RTX’s defense backlog sits at $109 billion, with Q1 2026 free cash flow of $1.31 billion — up 65% year-over-year. These are not headlines. These are contract schedules.
Palantir Is the Part People Skip
Slight tangent, but it matters.
The most interesting name in the defense complex right now isn’t a traditional contractor. Palantir (PLTR) just reported Q1 2026 revenue of $1.63 billion — up 85% year-over-year, marking the fastest revenue growth since the company’s 2020 direct listing. Net income quadrupled to $870.5 million. U.S. commercial revenue grew 133% year-over-year. The company raised its full-year 2026 revenue guidance to $7.65–$7.66 billion, implying 71% annual growth — well above the $7.27 billion consensus heading into that print.
Management described demand for its AI Platform as now outstripping supply. That’s not a typical software problem. That’s what happens when you’re embedded in active military targeting operations and allied governments can’t integrate the platform fast enough to meet operational demand. Palantir currently has 1,007 commercial customers for the trailing twelve months, up 31% year-over-year, with $4.45 billion in remaining performance obligations — up from $1.9 billion a year earlier.
The stock trades at a P/E above 154x. That’s the objection everyone raises, and it’s a legitimate one. But it trades expensive because it’s growing at 85% with 53% net profit margins and government contracts that don’t get switched mid-conflict. The switching cost isn’t financial — it’s operational. Once military command and control runs on a single AI platform, you don’t rip it out while operations are active.
Scenario Framework
Bull Case: Iran peace talks collapse or stall, supplemental defense appropriations pass, and procurement cycle extends through 2027–2028. LMT and RTX regain the war premium they gave back. NOC trades toward Morgan Stanley’s $765 target. Palantir’s Q2 guide reinforces the demand-exceeds-supply narrative, closing the gap toward the $193 consensus analyst target.
Base Case: Ceasefire discussions continue without resolution. Defense names trade range-bound, supported by backlog visibility but capped by peace-premium uncertainty. Palantir consolidates near current levels around $135–$140 following its YTD pullback of approximately 19%.
Bear Case: A durable ceasefire is struck, oil falls, and defense names reprice meaningfully lower. RTX — most exposed to munition restock cycles via Patriot missiles — sees the sharpest drawdown. NOC is most insulated given multi-decade nuclear modernization programs. Palantir’s premium valuation becomes difficult to defend if government contract timelines slip.
Active Trader Framework
The structural thesis for defense runs through China, the Indo-Pacific, and nuclear modernization — not just the current Middle East chapter. That framing changes how you manage position sizing around ceasefire headlines. Use peace-rumor dips as trim signals for the most reactive names (RTX), not wholesale exits. The multi-year backlog story keeps NOC and LMT relevant across both escalation and de-escalation scenarios.
For Palantir, the valuation risk is real but the moat is structurally deeper than traditional contractors. That’s a high-conviction, high-volatility position — not an infrastructure allocation. Understand which role each name plays in your book before a geopolitical headline moves markets 4% in a session.
What’s interesting is that the market’s best-performing themes right now — AI compute, geopolitical infrastructure, long-duration government spending — all converge in this one sector. The easy trade was the first pop in March. The institutional trade is everything that happens between now and 2028.
