In a Truth Social post Sunday, President Donald Trump revealed that he had directed the Department of War to hold off on planned strikes against Iranian power generation facilities and energy assets for a five-day period.

According to Trump, diplomatic discussions occurred Sunday under the leadership of Middle East envoy Steve Witkoff alongside Jared Kushner. Speaking with the press Monday, the president indicated both nations had achieved “major points of agreement” and suggested an accord might materialize quickly if negotiations maintain their current trajectory.

The diplomatic development drove the S&P 500 higher by approximately 1.4%, with the Dow Jones Industrial Average posting comparable gains. Brent crude oil futures tumbled 6.7%, settling at $99.27 per barrel.

Defense industry equities failed to mirror the broader market rally. Northrop Grumman (NOC) along with Lockheed Martin (LMT) both registered declines under 1% during early Monday sessions. General Dynamics (GD) and L3Harris Technologies climbed fractionally by less than 1%.

The defense sector has notably underperformed throughout the Iranian crisis. By Monday’s opening bell, the iShares Aerospace & Defense ETF had surrendered roughly 9% of its value since hostilities with Iran commenced — trailing the S&P 500 by approximately 4 percentage points during the identical timeframe.

Fiscal Uncertainty Weighs on Sector

In a weekend research note, Capital Alpha Partners analyst Byron Callan highlighted budgetary challenges impacting the sector. “Discussions surrounding a $200 billion supplemental appropriation and a $1.5 trillion DoD budget have negatively influenced U.S. defense market sentiment,” he noted.

Callan further referenced the Congressional deadlock over Department of Homeland Security appropriations as evidence of legislative dysfunction that may complicate efforts to secure expanded defense allocations.

The nuclear enrichment issue persists as a critical concern. Among Washington’s primary objectives in the Iran confrontation is addressing Tehran’s accumulation of weapons-grade enriched uranium.

Uranium is classified as highly enriched when it exceeds 20% concentration of the U-235 isotope. Intelligence assessments suggest Iran currently possesses material enriched to 60% U-235 — falling below the 90% benchmark required for nuclear armaments, yet substantially surpassing levels necessary for peaceful energy applications.

Diplomatic Engagement Extends into Monday

Trump verified Monday that dialogue would extend throughout the day. He expressed optimism that an agreement could emerge “very soon” should current momentum be sustained.

The five-day military operation suspension provides both nations a diplomatic opening. The outcomes of ongoing discussions — especially regarding Iran’s uranium reserves — will likely determine investor sentiment toward defense contractors in the immediate future.

Northrop Grumman stock traded down roughly 1.3% in early Monday activity, while Lockheed Martin retreated 0.5%. General Dynamics advanced 0.93%.
