Defense stocks in March 2026 :- the actual day-by-day numbers and catalysts behind the rally (LMT ATH $692, RTX $268B backlog, NOC B-21 combat debut, SHLD +72.8%)

I've been tracking the defense sector since the January buildup. Here's the complete performance log for March 2026 with the specific catalyst for every major move. This is a data post — specific numbers and their sources, not opinions. The Setup: February 28, 2026 Operation Epic Fury launched at approximately 3AM ET. First trading day: March 2. March 2 (Day 1): LMT: Opened near $654, hit all-time high intraday of $692.00, closed $675.81 (+3.23%) → Catalyst: F-35 Lightning IIs led the strikes. LMT in talks to quadruple THAAD production (96 → 400 units/year). $25.36B microelectronics contract confirmed. RTX: +6.5% → Catalyst: Tomahawk cruise missiles and Patriot systems — described in market reports as "the most sought-after commodities in the regional theater." NOC: +4.6% premarket, +6% by session → Catalyst: B-2 Spirit stealth bombers highlighted as cornerstone of the operation. B-21 Raider program accelerated. LHX: +5.3% → Catalyst: Tactical communications and electronic warfare systems deployed in operation. S&P 500: Fell. The divergence on Day 1 was the signal: defense up while everything else fell. March 3 — The Re-Rating Narrative Emerges: Institutional analysis began framing the move not as a "war premium" but as a structural re-rating. The key data point driving this framing: Historical defense P/E: 15–18x forward earnings March 2026 LMT P/E: ~31x The re-rating thesis is fueled by: "One Big Beautiful Bill Act" ($113B immediate military modernization, total defense budget crossing $1 trillion), and NATO allies targeting 5% of GDP on defense (up from 2%). The NATO 5% commitment is the most underappreciated driver — 32 nations simultaneously expanding procurement budgets is a multi-trillion dollar generational procurement cycle. March 4 — The AI Defense Layer: Palantir + LMT led a second day of defense rallying. The framing shifted to "Iron + Intelligence" — hardware and AI software as equal components of the defense re-rating. PLTR catalyst: February 27 government designation of Anthropic as supply chain risk → Palantir absorbs displaced DoD AI contracts → 2026 guidance revised to $7.19B (+61% YoY). LMT 2026 sales guidance: $77.5B–$80.0B — reflecting a defense environment where replenishment and air dominance modernization are the highest priorities. March 5 — Live Combat Validation: LMT +7% overnight. RTX +6%. LHX +5.3%. → U.S. Central Command released video of F-35 fighter jets taking off for Iran strikes. Live combat footage is the most valuable possible product validation. Every F-35 sortie is a sales event. Lockheed also announced AI-enhanced Combat Identification capability integrated into F-35's information fusion system — directly addressing the "Software-Defined Defense" valuation premium narrative. March 9 — Fresh All-Time Highs and Record Backlogs: LMT: Fresh all-time high of $692.00. Total gain from 52-week low: 69%. RTX backlog: Record $268 billion as of early March. NOC: +6% single session on B-21 Raider's confirmed operational combat debut. The Honest Valuation Picture: LMT: ~22x forward P/E (historical 15–18x) NOC: ~26x forward P/E (historical 15–18x) RTX: ~20x forward P/E (historical 14–16x) These are not cheap. The question is whether the multi-year budget expansion cycle (NATO 5%, $1T+ U.S. budgets, munitions replenishment) justifies sustaining elevated multiples for 3–5 years — as occurred post-9/11. One bear case from Capital Alpha Partners: "A successful operation that eliminates Iran's missile force may pivot future budgets toward lower-cost autonomous systems rather than expensive manned platforms." Real risk, but distant — the 2026–2029 story is replenishment of current weapons systems consumed in real operations. What I use to track the signals in real time: Management language in earnings calls. I run them through MoneySense AI — free AI sentiment analysis. Watching specifically for "contract timing" and "backlog conversion" language from LMT, NOC, RTX Q1 earnings (late April). First sign of hesitancy there is the early signal to reduce defense overweight. Second signal: Polymarket ceasefire probability. If it climbs above 60%, expect partial deflation of the "active war premium" component — though the structural budget expansion thesis likely holds independent of ceasefire.
