Markets already voted on this ceasefire. The day President Trump announced an interim memorandum with Iran, defense stocks sold off almost immediately. Lockheed Martin (NYSE: LMT) fell 5%, RTX (NYSE: RTX) lost 4%, while Northrop Grumman (NYSE: NOC) and L3Harris (NYSE: LHX) each dropped roughly 6%, signaling that investors had begun stripping a meaningful war premium from the sector on the assumption that diplomacy had finally gained the upper hand.

That assumption now seems premature. Continued Israeli military operations in Lebanon have emerged as one of the biggest tests of the agreement, placing Netanyahu’s government in collision course with the diplomatic framework Washington is trying to preserve.
The problem is, the market is starting to price that peace before the peace itself has been retested.
The Selloff Already Showed You The Premium
Run the numbers from deal day and the structure of this trade becomes obvious immediately. RTX dropped hardest among the names most tied to consumable munitions, because Patriot interceptors and AMRAAM restocking accelerates during active conflict and slows the second the shooting stops. That single fact explains why RTX is the most reactive name in this entire group on both sides of the move.
Lockheed fell too, despite sitting on a backlog north of $190 billion built almost entirely on multi-decade allied procurement that has nothing to do with whether Tehran and Washington are technically at peace this particular month.
That gap between the headline drop and the underlying contract base is the whole trade. The market sold a war premium across the board, even on the names whose real revenue runs on F-35 deliveries and PAC-3 production schedules signed years before this specific conflict started, which means the stocks most exposed to a Lebanon flare-up and the stocks most insulated from one just got priced as if they were the same thing.
Netanyahu Doesn’t Need To Kill The Deal Outright
He just needs to keep fighting in Lebanon, and he’s already told voters he plans to. Iran’s foreign minister has stated that any violation in Lebanon voids the ceasefire on every front simultaneously, which means this agreement isn’t insulated from a second theater the way most coverage is treating it.
Right now, Netanyahu is heading into elections this fall with his political survival tied to looking uncompromising on Hezbollah, and he’s said outright that the fighting continues “with an agreement, without an agreement.” Defense Minister Israel Katz has vowed to keep Israeli troops in southern Lebanon regardless of what Washington prefers, and Trump has reportedly told Netanyahu in blunt, documented terms that continued strikes risk unraveling the entire framework he just built with Tehran.
None of that belongs to some distant scenario investors may have to price one day. The disagreement is already unfolding between the two governments that helped shape this framework, and the 60-day clock resets the moment Iran concludes the ceasefire has been violated.
The conflict that originally drove the war premium into RTX, Lockheed, and other defense stocks doesn’t need a new trigger. Netanyahu has already signaled the course he intends to take.
Congress, Not Tehran, May Move These Stocks First
Here’s where the setup gets genuinely asymmetric, and where I think most of the coverage on this trade is looking in the wrong direction entirely.
The war already drained U.S. stockpiles of Patriot interceptors and Tomahawks faster than planners expected, which is why the White House recently summoned Lockheed, RTX, Boeing, Northrop, L3Harris, and Honeywell Aerospace specifically to address the shortage. Demand for replenishment isn’t theoretical and isn’t contingent on whether Iran stays calm. It already exists.
The constraint is that those framework agreements can’t be fully funded until a defense appropriations bill clears Congress, and that legislative timeline runs on its own schedule, completely disconnected from both the ceasefire and from whatever Netanyahu decides to do next week in Beirut.
That creates two outcomes stacking on top of each other rather. If the deal holds and Lebanon stays contained, defense stocks likely keep grinding lower on a fading war premium, but the replenishment cycle from depleted stockpiles still happens regardless, because that demand was created by the war that already occurred.
If Netanyahu escalates far enough to void the framework, you get the replenishment cycle and a reignited war premium landing in the same quarter – and RTX, given its munitions exposure, is the name most levered to that exact combination arriving at once.
The Watchlist, Not The Trade
I’m not chasing defense stocks today. The selloff was rational, the war premium needed to come out, and chasing a bounce on a ceasefire that the intelligence community itself doubts is a bet on a headline rather than a thesis.
But I’m keeping RTX and Lockheed and others on the watchlist, because procurement cycles like this one rarely announce themselves on the day they actually begin. They start in appropriations subcommittees, in Pentagon meetings nobody covers, in stockpile assessments that leak out months before contracts get signed… and by the time the market reacts to Netanyahu’s next move in Lebanon, the funding decision that matters will have already been made.
