Iran conflict stocks: defense, oil, drones, cyber.

Updated September 25, 2026: where things stand on Day 210

• April 8: a two-week US–Iran ceasefire, mediated by Pakistan, took effect. On April 21 Trump extended it indefinitely while keeping the naval blockade (declared April 12–13) in place.
• June 12–17: new ceasefire terms were agreed and, on June 17, the US and Iranian presidents signed the Islamabad Memorandum — a 60-day extension to negotiate final terms. The blockade was paused.
• July 8: the interim deal collapsed after Iran struck commercial ships in the Strait of Hormuz that bypassed its preapproved route. Trump declared the ceasefire over.
• July 14: the US reinstated the naval blockade. It remains in place as of September 25.
• September 22–23: at talks on the sidelines of the UN General Assembly in New York, mediated by Qatar, Pakistan and Egypt, Iran presented a road map that includes a regionwide ceasefire of up to 60 days, a phased reopening of the Strait of Hormuz and an end to the US blockade, per sources briefed by the mediators (The National, Sept 23). Trump has ruled out lifting the blockade before Iran shows "sufficient goodwill."
• Hormuz traffic is disputed: the US says 60–70% of pre-war oil flow has been restored; independent tracking cited by GlobalSecurity.org counted 13 vessel crossings on September 24.
• Oil: Brent crude closed at $106.60 on September 24, 2026, up 3.4% on the day, after reports of talks on a phased reopening of the strait (CNBC; Fortune had Brent at $104.67 at 10 a.m. ET the same day).

Congress and defense/energy stocks since February 28

Based on GovGreed's analysis of deduplicated STOCK Act disclosures (data as of September 25, 2026), 18 members of Congress disclosed trades dated February 28, 2026 or later in 13 of the 18 defense and energy tickers we track for this page (LMT, RTX, NOC, GD, HII, LHX, BA, KTOS, AVAV, PLTR, XOM, CVX, COP, OXY, ITA, XAR, PPA, XLE). 8 disclosed purchases and 11 disclosed sales (2 members did both; 1 disclosed only an exchange), across 23 distinct member–ticker pairs.

• The largest by band: Chevron (CVX) sales in the account of Rep. Michael McCaul's spouse (R-TX) — $100,001–$250,000 on March 4, $500,001–$1,000,000 on March 13 and $15,001–$50,000 on March 23, 2026, all filed April 10.
• The most active: Rep. Gilbert Cisneros (D-CA, House Armed Services) disclosed both purchases and sales of Palantir (PLTR) between March and July 2026, plus an AeroVironment (AVAV) purchase on March 3 and sales in early July — each line in the $1,001–$15,000 or $15,001–$50,000 band.
• Rep. Ro Khanna (D-CA) disclosed a PLTR purchase on July 7, 2026 ($1,001–$15,000).

Two caveats. The STOCK Act allows up to 45 days to disclose, so trades from August and September are still arriving. And most of these disclosures sit in the lowest bands on the form — the form reports a range, never an exact amount, and never says why a trade was made.

Not financial advice. All data from public federal disclosures.

Originally published April 23, 2026 (Day 54)

Everything below this line is our original April 2026 analysis. Prices, returns, valuations and ceasefire details reflect April 22–23, 2026 and have not been updated. Roles have been corrected where they changed.

What was happening on Day 54 (April 22, 2026)

The U.S.-Israel strikes against Iran began February 28, 2026 with Operation Epic Fury — almost 900 strikes in 12 hours targeting nuclear facilities, missile bases, air defenses, and senior leadership. Supreme Leader Ali Khamenei was killed in the Israeli portion of the operation, with his death announced March 1. Iran retaliated with missile and drone attacks against Israel, U.S. bases in the Gulf, and U.S.-allied Arab states, then closed the Strait of Hormuz on March 4.

A fragile two-week ceasefire took effect April 8, but as of April 22 talks were stalled. Trump had extended the ceasefire on April 21 while demanding Iran transfer its highly-enriched uranium stockpile to U.S. custody — a demand Iran has publicly rejected. The U.S. naval blockade on Iran-linked tankers remains active. The IEA called the Hormuz closure "the largest supply disruption in the history of the global oil market" — roughly 25% of seaborne oil and 20% of LNG transit the strait.

For markets in April, defense, energy, cybersecurity, and counter-drone names were at or near all-time highs, while airlines and oil-sensitive consumer names were falling.

Sectors hit hardest — April 2026 snapshot

Who in Congress traded before the war (April 2026)

By April 2026, the STOCK Act 45-day disclosure window meant trades made in Q4 2025 / January 2026 were public. For trades since the war began, see the September update at the top of this page. "Outcome" figures below are as of April 2026. Sources are inline; trades are from the Periodic Transaction Reports filed with the House Clerk and Senate eFD systems.

The committee linkages that matter most for an Iran-themed signal: House Armed Services (authorizes DoD budget — Cisneros, Khanna, McClain), House Foreign Affairs (McCaul chaired it through January 2025), Senate Armed Services (Tuberville), and the quietest committee with the highest information value — House/Senate Intelligence. GovGreed's bill-first scoring engine flags any LMT/RTX/NOC/GD buy by an Armed Services or Foreign Affairs member at A-tier confidence (60+).

The counter-thesis (April 2026)

This is not a free lunch. Three fault lines.

1. Valuation

The S&P 500 Aerospace & Defense sub-index trades at ~32x forward earnings; the broader U.S. A&D industry now sits at 44.8x P/E versus a 3-year average of 32.1x. Defense EV/Sales multiples are nearly triple early-2000s levels. Earnings have to beat elevated estimates just to maintain price — and Q1 2026 estimates have already been revised down (GD: 12% growth vs. 15% expected at start of year).

2. Ceasefire snap-back risk

XLE fell 10.24% in the week after Trump floated ending the war — the worst-performing S&P sector that week. LMT and RTX are both down YTD despite the war because the move was already priced in pre-Feb 28. A real ceasefire — even a fragile one — collapses the geopolitical premium fast.

3. Headline whiplash

Day-to-day price action is dictated by single Truth Social posts. The April 17 video of empty tankers turning away from Hormuz pumped USO 6%. The April 19 ceasefire-extension post drained energy 4%. This is a trader's market, not an investor's. Position sizing matters more than ticker selection.

4. The buy-the-rumor trap

Defense outperformed massively in the 6 months leading up to February 28. Since the actual war started, LMT and RTX are flat-to-down. Bargain-hunters keep buying the dip and getting whipsawed. The clean trade was Q4 2025 — late entrants are paying for someone else's victory lap. That's the trade Mullin and McCaul made.

5. Houthi / Red Sea wildcard

Houthis announced an end to Red Sea attacks on October 10, 2025 (Gaza peace plan) — then resumed strikes on Israel March 28, 2026. Container-shipping costs (Suez vs. Cape of Good Hope re-routing) have not normalized. This is a separate, longer-tail disruption from Hormuz that affects ZIM, MATX, FDX, and global retailers — not directly defense.

What our scoring engine flagged in April 2026

GovGreed's signal engine fuses seven layers (politician quality, herd behavior, bill correlation, technical context, sector momentum, contribution patterns, lobbying alignment). Iran-themed signals firing at A-tier+ as of April 23, 2026 include defense-prime accumulation by Armed Services / Foreign Affairs members, a defense-ETF herd signal across 7 politicians (Cisneros + Tuberville + Khanna + others), and pre-vote insider buying clustered around the Sentinel ICBM and B-21 line items in the FY26 NDAA.
