A complete guide to defense stocks that have historically surged during wars — with real return data from WWII to 2026. Find out which tickers to watch and why they move.
When a war breaks out, most investors panic. But a small group of stocks quietly starts climbing.
Defense contractors — the companies that build fighter jets, missiles, radar systems, and military software — are almost always in that group. Their revenue is tied directly to government defense budgets, which go up when conflict escalates.
This guide covers exactly which defense stocks have surged during past wars, what the data looks like, and what is happening in 2026.
Why Defense Stocks Rise During Wars
The logic is straightforward. Governments need weapons, logistics systems, surveillance technology, and military equipment during conflicts. They buy these from publicly traded defense contractors on long-term contracts.
Unlike most businesses that struggle in uncertain times, defense contractors often *thrive* during them. Their contracts are:
- Government-backed — the customer does not go bankrupt
- Long-term — often 5–10 year deals with built-in price escalation
- Hard to cancel — once a weapons program starts, stopping it is costly and politically difficult
On top of that, investors treat defense stocks as a hedge during geopolitical fear. When the news gets scary, money flows into defense.
Historical Returns: Defense Stocks Across Major Wars
Here is what the data shows across major U.S. military conflicts. These returns cover the primary mobilization period of each conflict — roughly the first 12–36 months after major escalation.
Korean War Era (1950–1953)
The Korean War triggered the first major U.S. military buildup of the Cold War. Defense budgets roughly tripled between 1950 and 1953.
- General dynamics-era contractors averaged +35–45% returns in the first year of escalation
- Steel and aluminum companies that supplied military manufacturing also surged
- The S&P 500 overall gained about +18% in this period — defense significantly outperformed
Vietnam War Peak (1965–1968)
The peak escalation period of Vietnam saw the highest U.S. troop levels and the largest war spending of that era.
- Defense electronics and aerospace companies averaged +50–65% returns at peak escalation
- Companies making aircraft components, munitions, and communications equipment led the gains
- The broader market was volatile but defense sector outperformed by roughly 2–3x
Gulf War (1990–1991)
The Gulf War was short but intense. The defense sector spiked sharply on the invasion of Kuwait and sustained through the conflict.
- Raytheon (Patriot missile systems) saw significant revenue and stock gains
- Northrop and Lockheed gained +30–50% from the conflict announcement through post-war period
- The war lasted only 100 hours on the ground, so gains were front-loaded into the announcement period
Post-9/11 Decade (2001–2011)
This is the most documented modern wartime defense rally. The wars in Afghanistan and Iraq ran simultaneously and drove a decade of elevated defense spending.
- Lockheed Martin (LMT): roughly +312% total return over the decade
- Northrop Grumman (NOC): roughly +295% total return
- Raytheon (RTX predecessor): roughly +280% total return
- General Dynamics (GD): roughly +256% total return
- The S&P 500 over the same period was essentially flat to slightly negative
- Defense sector outperformed the broad market by several hundred percentage points
Russia-Ukraine War Era (2022–2026)
The ongoing Russia-Ukraine conflict and related NATO spending increases have created the most sustained modern defense boom outside the post-9/11 era.
- Every NATO member has increased defense spending commitments
- U.S. supplemental aid packages added tens of billions in new defense contracts
- European defense companies listed on U.S. exchanges also benefited
Returns from February 2022 (invasion) through early 2026 (estimated):
| Company | Ticker | Approximate Return |
|---|---|---|
| Lockheed Martin | LMT | +68% |
| RTX Corporation | RTX | +55% |
| Northrop Grumman | NOC | +63% |
| General Dynamics | GD | +51% |
| L3Harris Technologies | LHX | +47% |
| Palantir Technologies | PLTR | +200%+ |
| TransDigm Group | TDG | +89% |
*Note: These are approximate figures based on available market data. Always verify current prices and returns before making investment decisions.*
The New Category: Defense Tech Stocks
The 2022–2026 period introduced a new subcategory of defense beneficiary: defense technology companies.
Traditional defense contractors build hardware — jets, missiles, ships. But modern warfare increasingly runs on software, data analytics, AI, and drone systems. Companies operating in this space have seen explosive growth.
Palantir Technologies (PLTR) is the clearest example. It provides AI-driven data analysis platforms to the U.S. military and intelligence agencies. Its stock gained over 200% from the start of the Ukraine conflict through early 2026.
Other emerging defense tech names include drone manufacturers, satellite communications companies, and cybersecurity firms with government contracts.
Defense ETFs: A Simpler Way to Invest
If picking individual defense stocks feels complicated, ETFs give you broad exposure to the entire sector in a single trade.
| ETF | Full Name | What It Holds |
|---|---|---|
| ITA | iShares U.S. Aerospace & Defense ETF | LMT, RTX, NOC, GD, and more |
| XAR | SPDR S&P Aerospace & Defense ETF | Equal-weighted defense and aerospace |
| PPA | Invesco Aerospace & Defense ETF | Broader defense supply chain |
| SHLD | Global X Defense Tech ETF | Defense + cybersecurity + AI defense |
ETFs reduce the risk of picking the wrong individual company and give you diversified exposure to the sector theme.
What Drives Defense Stock Performance During Wars
Understanding *why* defense stocks move helps you evaluate new situations as they develop.
1. Defense Budget Announcements
When Congress approves a defense budget increase or a supplemental spending package, defense stocks rally almost immediately. The market is pricing in future contract revenue.
2. Specific Weapon System Deployments
If a particular weapon system is used prominently — like Raytheon's Patriot missiles during Gulf War or Ukraine — the company behind it gets immediate attention and investor inflows.
3. NATO Spending Commitments
When NATO allies commit to increasing their defense spending (the 2% of GDP target), it creates additional revenue opportunities for U.S. defense contractors who supply many of these allies.
4. Long-Term Contract Wins
A single major contract win — like a new fighter jet program or a missile defense system — can be worth tens of billions over a decade. The stock moves when these are announced.
How to Stay on Top of Defense Sector News
Defense stock performance is heavily news-driven. Budget approvals, contract wins, conflict escalations, and diplomatic developments all move these stocks.
Reading and understanding this news quickly gives you a real edge.
The **MoneySense AI Chrome Extension** is designed for exactly this. Install it in your browser, and whenever you open a financial article or SEC filing about a defense company, it instantly analyzes the content and tells you in plain English: is this good or bad news for investors, what are the key takeaways, and what should you watch next. It removes the jargon and saves you 30 minutes of research on every article.
Generating Income on Defense Stocks You Already Own
If you already hold defense stocks — or are considering buying them — you can generate additional income from your position using options.
Selling covered calls on stocks like LMT, RTX, or NOC is a common strategy for long-term holders. You collect a premium from other investors while you hold your shares. In a volatile, geopolitically uncertain market, these premiums tend to be higher than normal.
**Option Wheel Tracker** makes it easy to manage this. It tracks all your covered calls and cash-secured puts in one place, calculates your total income collected, and helps you stay organized across multiple positions. If you are running a wheel strategy on defense names, this tool keeps everything clear and disciplined.
The Risks of Investing in Defense During Wars
Defense investing is not a guaranteed win. There are real risks to understand:
War can end suddenly. Defense stocks often drop sharply when peace deals are reached or wars end faster than expected. The market had priced in continued spending, and a ceasefire reprices that quickly.
Budget cuts follow wars. After major conflicts, defense budgets often get trimmed. The post-Vietnam period and post-Cold War era both saw significant cuts that hurt defense stocks.
Concentration risk. If you hold too many defense stocks, your portfolio moves together with every geopolitical headline — both up and down.
Ethical considerations. Some investors choose not to hold defense companies for personal reasons. That is a legitimate factor to weigh.

- The 2022–2026 Russia-Ukraine era has been the most recent sustained defense rally
- Defense ETFs (ITA, XAR, PPA) offer simple, diversified sector exposure
- New defense tech names like Palantir represent the modern version of the wartime defense trade
- News-driven performance means staying informed is a key edge
Frequently Asked Questions
Do defense stocks always go up during wars?
Not always. The timing matters significantly. Stocks often rally at the *start* of a conflict when spending expectations rise. If a war ends quickly or defense budgets disappoint, stocks can give back gains. The strongest sustained gains happened during the decade-long post-9/11 conflicts.
What is the best defense stock to buy during a war?
This depends on which systems and capabilities are being deployed. During the Ukraine conflict, missile defense systems (RTX/Raytheon) and AI/data (Palantir) were particularly relevant. Researching which specific products are being used in a given conflict helps identify the most direct beneficiaries.
Are defense ETFs better than individual defense stocks?
For most regular investors, yes. ETFs reduce the risk of picking the wrong company and give you exposure to the overall sector trend without needing to analyze individual contracts and programs.
What happens to defense stocks after a war ends?
They typically decline — sometimes sharply — as the market reprices lower future defense spending. However, if a new conflict emerges or NATO spending commitments remain elevated, the decline may be limited. The post-Ukraine situation will be an important case study.
