Stars, Fading

For two years, the defense trade was the one you could explain to anyone. The world was rearming — Russia in Ukraine, the Middle East aflame, China looming, every European capital tearing up decades of pacifist budget orthodoxy — and the companies that make the weapons were going to sell more of them for years to come. It was simple, it was geopolitically obvious, and it worked spectacularly. Germany's Rheinmetall, the universal proxy for European rearmament, rose roughly 150% across 2025. American giants — Lockheed Martin, RTX, Northrop Grumman — climbed to record highs. Defense became the rare sector a growth investor and a doomsayer could buy together, each for their own reasons.

And then, in the spring of 2026, the trade did something that should be studied, because it is one of the oldest and most reliable warnings in markets. A real war arrived — a ten-day shooting conflict between the United States and Iran, exactly the kind of event the entire thesis was built to anticipate — and the defense stocks fell. Since the conflict began, shares of Lockheed, Northrop and RTX have dropped between 13% and 26%. The catalyst the bulls had been waiting for finally came, and it marked not the launch but the top.

When an asset falls on the news it was supposed to rise on, the news was already in the price. That is the situation defense investors now find themselves in, and the people who understand the sector best have begun, quietly and not so quietly, to head for the exits while the headlines still scream.

The war that didn't help

Start with the Iran conflict, because it is the cleanest natural experiment the defense thesis could have asked for, and it failed.

In theory, a war between America and Iran is unambiguously bullish for defense contractors: missiles get fired and must be replaced, the case for higher budgets strengthens, the threat environment that justifies the whole sector becomes vivid and undeniable. There was an early reflexive pop. But it did not hold. As the analyst Douglas Harned of Bernstein noted, the conflict wound down after about ten days with Iran's offensive capabilities substantially degraded — and the stocks promptly began giving back their gains, with Bernstein warning that there was little on the horizon to revive them before the November midterm elections. "US defense stocks see no Iran war lift after early surge," ran one headline; the market had spent two years pricing perpetual escalation, and a war that was decisive and brief was, perversely, bearish — because it removed the open-ended threat the valuations depended on.

This is the trap of a sector that has priced in a permanent emergency. Good news for the world — a war that ends quickly, a ceasefire, a degraded adversary — becomes bad news for the stocks, while the only thing that could sustain the valuations is exactly the endless, escalating conflict that the bulls would never admit they were rooting for. When your investment thesis requires the world to keep getting worse forever, the world's occasional refusal to cooperate is a structural risk.

The patron turns hostile

The second pillar to crack was the one no defense bull thought to worry about: the customer. The American defense sector has one dominant buyer — the US government — and for decades the relationship has been comfortable, even cozy. Under the Trump administration, it has turned adversarial in ways the stock prices have been slow to absorb.

On paper, the news was a dream: the administration proposed the largest defense budget in American history, a FY2027 plan approaching $1.5 trillion to build what it called a "Dream Military." And yet, when it was announced, the contractors' shares fell — Northrop down 5.5%, Lockheed 4.8%, RTX 2.5%. The reason was buried in the fine print and the president's own words. Trump has publicly lambasted defense CEOs over their pay and their stock buybacks, and in January signed an executive order that would bar major contractors from buying back shares or paying dividends until they improved production. The language was blunt: effective immediately, the order declared, they are "not permitted in any way, shape, or form to pay dividends or buy back stock, until such time as they are able to produce a superior product, on time and on budget." He has called for capping executive pay across the industry. The largest budget in history arrived chained to a demand that the money go into factories and weapons rather than into shareholders' pockets — which is wonderful for the warfighter and considerably less wonderful for the stock. A patron who showers you with orders while forbidding you to return cash to your owners is not the patron the valuation assumed.

Great results, falling shares

The third and most telling crack is the one that appears in the numbers themselves, where the businesses are doing well and the stocks are falling regardless — the single most reliable signature of a momentum trade that has run its course.

Rheinmetall is the case study. Operationally, the company is firing on every cylinder: full-year 2025 sales grew 29%, it has guided to a staggering 40–45% revenue increase in 2026, and it expects its order backlog to roughly double toward €135 billion on the back of fresh contracts from Germany, NATO and Ukraine. These are extraordinary, almost unheard-of growth figures for an industrial company. And yet the stock has fallen roughly 38% from its late-January peak, and even missed its 2025 sales estimate (€9.94 billion against an expected €10.53 billion) despite that 29% growth. A company can grow 45% and still be a bad stock, if the price already assumed it would grow 60%. The European defense ETF has slipped into the red for the year, and analysts now describe 2026 as a period not of expansion but of "consolidation" — a polite word for the phase in which a story stops being about a thrilling theme and starts being about whether individual companies can justify the multiples the theme handed them.

The rearmament is real, and may well prove durable — Europe has committed to lifting defense spending toward 5% of GDP over the coming decade, and the bulls who argue the scale is still underappreciated are not obviously wrong. But "the spending is real" and "the stocks are cheap" are different claims, and the gap between them is exactly where money is lost.

The bankers ring the bell

Which brings us to the surest sign of all that the easy money has been made: the rush to sell new defense stock to the public, precisely now.

After two years in which the sector's incumbents soared, the investment banks have lined up a wave of defense initial public offerings to capture the enthusiasm — chief among them KNDS, the Franco-German maker of Leopard tanks, targeting a dual listing in Frankfurt and Paris in the summer of 2026. The tell is in the price. KNDS's expected valuation has already been cut from an initial €25 billion floated by its bankers to around €18–20 billion, a sharp markdown that the bankers themselves attribute to fading investor appetite "after Rheinmetall's derating." A satellite maker, OHB, is lining up behind it. The owners of these businesses — including governments looking to monetize their stakes — are choosing this exact moment, after a 150% run and a sector-wide rollover, to convert private holdings into public cash. Insiders and bankers do not rush IPOs to market at the bottom of a theme. They rush them out at the top, while the story is still famous enough to sell and before the audience notices the share prices have already turned.

None of this means the weapons makers are bad businesses or that Europe's rearmament is a mirage. The orders are genuine, the backlogs are vast, and a decade of elevated defense spending is a reasonable base case. But the stocks have already lived that future once, in advance, and are now discovering the oldest lesson of thematic investing: the theme and the trade are not the same thing, and the trade tends to end while the theme is still true. The world will keep rearming. That was never the question. The question was what you paid for the privilege of believing it — and the answer, set against record highs, a war that ended too soon, a hostile patron, and a banker's IPO calendar full to bursting, is: too much.

The stars of 2025 are still bright. They have simply started, one by one, to fade — and the people closest to the light are the first to reach for their coats.
