Defense Stocks: A Complete Investor's Guide for 2026
Defense stocks — also called military stocks or war stocks — represent publicly traded companies that generate a material portion of their revenue from government defense contracts, military hardware, weapons systems, aerospace manufacturing, and national security services. The sector is often studied by investors for its countercyclical characteristics: while consumer discretionary and growth sectors weaken in economic downturns, defense budgets are typically protected by government appropriations and long-term procurement programs that continue regardless of economic conditions.
In 2026, heightened geopolitical tension across multiple regions, the largest European rearmament since the Cold War, record U.S. defense appropriations, and the rapid integration of AI, drone systems, and space capabilities into military strategy have combined to bring sustained investor attention to the defense sector. This guide provides a structured, fact-based framework for researching defense stocks: what they are, how the sector is organized, which companies investors commonly research, and — critically — the genuine risks and evaluation criteria that separate informed investment from reactive trading.
What Are Defense Stocks?
Defense stocks are equities in companies whose primary business involves manufacturing, developing, or providing services related to national security and military capability. The sector is formally classified as part of the Industrials sector (GICS classification) under the Aerospace & Defense industry group for most major indices, though some defense-oriented technology companies appear in the Technology or Communication Services sectors depending on their business mix.
The key characteristic that distinguishes defense stocks from most other equities is their government as primary customer. Revenue comes predominantly from defense procurement contracts awarded by the U.S. Department of Defense (DoD), allied government defense ministries, and intelligence agencies. These contracts are often multi-year, cost-plus or fixed-price structures, providing relatively predictable revenue and cash flow visibility compared to commercial businesses exposed to consumer demand fluctuations.
Defense vs. Aerospace: Understanding the Overlap
The terms "defense" and "aerospace" are often used interchangeably in financial media, but they are not identical. Many of the largest defense companies — including RTX, GE Aerospace, and Boeing's defense division — have dual commercial aviation businesses alongside their military programs. This means their stock performance is influenced by both defense budget cycles and commercial aircraft demand. Pure defense-oriented investors often prefer companies with limited commercial aviation exposure for cleaner sector correlation.
Why Defense Stocks Are Attracting Investor Attention in 2026
Three structural forces have converged to create what many defense analysts describe as a multi-year defense spending upcycle.
1. Record Global Defense Budgets
The United States military expenditure reached approximately $997 billion in 2024 — accounting for roughly 37% of total global defense spending. The U.S. defense budget has grown consecutively in real terms for multiple years, driven by the National Defense Authorization Act (NDAA) and supplemental appropriations. Beyond the U.S., NATO members are under sustained pressure to reach and maintain the 2% of GDP defense spending threshold, with many European members significantly increasing their defense budgets. Germany launched a €100+ billion special defense fund; Poland has committed to defense spending exceeding 4% of GDP; and Japan has approved a doubling of its defense budget over five years. This represents a structural, multi-year demand environment for defense contractors.
2. Active Conflict Replenishment Demand
Ongoing conflicts — particularly in Ukraine and the Middle East — have driven accelerated consumption of munitions, missiles, air defense systems, and precision weapons. U.S. and allied governments have transferred significant equipment from existing stockpiles to allies, generating direct replacement contracts with prime defense contractors. Artillery rounds, Patriot interceptors, HIMARS systems, and guided bomb units have all been ordered in quantities not seen in decades, benefiting companies that manufacture them.
3. Technological Modernization: AI, Space, and Autonomous Systems
Military modernization programs are integrating AI-enabled targeting, autonomous drone systems, hypersonic weapons, cyber defense, and space-based capabilities at an accelerating pace. This creates adjacent technology demand that benefits both traditional defense prime contractors and emerging defense technology companies (the "tech defense" segment). Programs like JADC2 (Joint All-Domain Command and Control), directed energy weapons, and satellite communications are funding multi-billion dollar development contracts.
4. Long-Cycle Program Visibility
Unlike most industries where customer demand is variable quarter-to-quarter, major defense programs span decades. Lockheed Martin's F-35 program is a multi-decade production run. Northrop Grumman's B-21 Raider stealth bomber program extends well into the 2040s. The Sentinel ICBM modernization program is a $100+ billion multi-decade effort. These long-duration programs give investors unusual forward revenue visibility when assessing established prime contractors.
The Four Sub-Segments of the Defense Sector
Defense stocks do not represent a monolithic category. The sector spans multiple distinct business models, risk profiles, and drivers. Understanding which sub-segment you are investing in is essential for correctly assessing risk, growth rate expectations, and valuation.
| Sub-Segment | What They Do | Revenue Model | Risk Level | Margin Profile | Example Companies |
|---|---|---|---|---|---|
| Prime Defense Contractors | Design and integrate major weapons systems, aircraft, ships, missiles, and satellites | Multi-year government contracts — cost-plus and fixed-price | Moderate — program execution and budget exposure | Operating margins typically 10–15%; stable and predictable | Lockheed Martin (LMT), RTX Corp (RTX), Northrop Grumman (NOC), General Dynamics (GD) |
| Second-Tier Contractors & Subcontractors | Manufacture components, subsystems, and specialized parts for prime contractors and DoD | Long-term supply agreements; cost-plus and fixed-price DoD subcontracts | Moderate-High — program dependency; supplier concentration | Margins vary widely; niche players often higher than primes | TransDigm (TDG), HEICO (HEI), Curtiss-Wright (CW), L3Harris (LHX), BWX Technologies (BWXT) |
| Defense Technology (Cyber, Space, AI) | Provide software, intelligence services, satellite systems, cyber defense, and AI capabilities | Government IT contracts; classified programs; SaaS/platform fees | Moderate — budget and clearance dependencies; fast-evolving competition | Software-oriented; typically higher operating margins; faster growth potential | CACI International (CACI), Leidos (LDOS), Science Applications Int'l (SAIC), Palantir (PLTR) |
| Emerging Defense / Next-Gen Platforms | Develop autonomous systems, drones, hypersonic weapons, counter-drone technologies | Development contracts; R&D grants; milestone-based DoD programs (OTA contracts) | High — pre-volume production; program risk; funding uncertainty | Often loss-making or thin margins; high speculative premium | AeroVironment (AVAV), Joby Aviation (JOBY), Kratos Defense (KTOS), Rocket Lab (RKLB) |
Key U.S. Prime Defense Contractors
The following companies are the most widely researched U.S. defense prime contractors by investors and analysts as of 2026. This table is for educational reference only and does not constitute investment advice. All data and company positions change; always verify with current filings before making any investment decision.
| Company | Ticker | Exchange | Primary Business | Key Programs | Key Note for Investors |
|---|---|---|---|---|---|
| Lockheed Martin | LMT | NYSE | Fighter jets, missiles, helicopters, space systems | F-35 Lightning II, Patriot PAC-3 missiles, Black Hawk helicopters (via Sikorsky), THAAD | Largest U.S. prime contractor by defense revenue; F-35 is the world's most expensive weapons program with production expected past 2040; strong international order book; consistent dividend payer |
| RTX Corporation | RTX | NYSE | Missiles, air defense, engines, avionics | Patriot systems, Raytheon missiles (Stinger, AMRAAM), Pratt & Whitney engines, Collins avionics | Dual defense/commercial aerospace exposure; commercial aviation recovery and defense rearmament both act as positive drivers; Pratt & Whitney GTF engine inspection program creates short-term cash headwind |
| Northrop Grumman | NOC | NYSE | Stealth aircraft, missiles, space systems, shipbuilding (via Newport News stake) | B-21 Raider stealth bomber, Sentinel ICBM, satellites, Triton drone | $95B+ backlog as of 2025; B-21 and Sentinel are classified "must fund" national security programs; limited commercial aviation exposure makes revenue more defense-pure; space and missile systems positioned for multi-decade growth |
| General Dynamics | GD | NYSE | Combat vehicles, submarines, IT services, jets | M1 Abrams tanks, Virginia-class submarines, Gulfstream business jets, GDIT government IT | Diversified across defense hardware (marine, combat systems) and defense IT services; Gulfstream division provides commercial exposure; submarine demand is structurally long-cycle due to AUKUS and Virginia-class program |
| L3Harris Technologies | LHX | NYSE | Communications, electronic warfare, ISR systems, sensors | Military communications, F/A-18 sensor systems, tactical data links, night-vision equipment | Mid-large cap prime; pure-play defense (minimal commercial aviation); strong in electronic warfare, communications, and C4ISR; merger of L3 and Harris in 2019 created a major tier-1 competitor to legacy primes |
| Boeing (Defense) | BA | NYSE | Military aircraft, space launch, helicopters | F-15EX, AH-64 Apache, KC-46 tanker, Space Launch System (SLS) | Boeing's defense division is a substantial business but operates alongside a troubled commercial aviation division; commercial aircraft crisis (quality control, debt) means Boeing stock is not a pure defense play; defense investors should be aware of commercial headwinds affecting the consolidated entity |
Second-Tier Contractors & Specialty Defense Plays
Below the large prime contractors sits a layer of highly profitable, specialized defense companies that supply critical components, subsystems, and services. These companies often carry higher operating margins than prime contractors (because they supply niche, high-switching-cost parts) and can offer different growth profiles — but also higher program concentration risk.
| Company | Ticker | Exchange | Specialty | Key Note |
|---|---|---|---|---|
| TransDigm Group | TDG | NYSE | Proprietary aerospace components (sole-source supplier) | Highly acquisitive business model; builds portfolio of sole-source, non-replicable aerospace parts; strong pricing power; high leverage by design; mix of defense and commercial aerospace revenue |
| HEICO Corporation | HEI | NYSE | FAA-approved aircraft parts, defense electronics | Niche position supplying FAA-approved replacement parts (PMAs) at lower cost than OEM; defense electronics unit; long history of consistent growth; founder-operator culture |
| Curtiss-Wright Corp | CW | NYSE | Defense electronics, naval propulsion, industrial automation | Critical supplier of drive motors for naval nuclear reactors and submarine propulsion; high defense content; consistent dividend history; significant Navy program dependency |
| AeroVironment | AVAV | NASDAQ | Tactical drones and loitering munitions | Switchblade loitering munition became prominent in Ukraine conflict; PUMA, Raven, and Wasp small UAS systems; pure-play drone manufacturer with exposure to both DoD and allied government customers; higher growth profile; also higher execution risk |
| Kratos Defense | KTOS | NASDAQ | Unmanned systems, satellite communications, microwave electronics | Key player in target drone systems (UTAP-22) and next-generation autonomous combat aircraft concepts; growing hypersonic test systems business; pre-volume production on most programs; higher speculative risk than established primes |
| CACI International | CACI | NYSE | Defense IT, intelligence, cyber, analytics | Government IT and intelligence services; classified program exposure; consistent federal contract wins; defense tech play with lower hardware execution risk than platform manufacturers |
Defense ETFs: Sector-Wide Exposure
Investors seeking broad exposure to the defense sector without concentrated single-stock risk can use Exchange-Traded Funds. Note that most U.S. defense ETFs are formally classified as "Aerospace & Defense" ETFs and include commercial aviation companies alongside pure defense names. Investors seeking purer defense exposure should review fund holdings before purchasing.
| ETF Name | Ticker | Index / Approach | Key Holdings | Expense Ratio (Approx.) | Key Note |
|---|---|---|---|---|---|
| iShares U.S. Aerospace & Defense ETF | ITA | Dow Jones U.S. Select Aerospace & Defense Index | GE Aerospace, RTX, Boeing, Lockheed Martin, Northrop Grumman | 0.40% | Largest defense ETF by assets (~$15B AUM); market-cap weighted with capping; includes commercial aerospace names like Boeing; most liquid and widely held sector ETF in this space |
| Invesco Aerospace & Defense ETF | PPA | SPADE Defense Index | RTX, L3Harris, Booz Allen Hamilton, CACI, Lockheed Martin | 0.57% | Broader than ITA; includes defense IT and services companies like Booz Allen and CACI; modified equal-weight provides less mega-cap dominance |
| SPDR S&P Aerospace & Defense ETF | XAR | S&P Aerospace & Defense Select Industry Index | TransDigm, HEICO, Curtiss-Wright, Axon Enterprise, Mercury Systems | 0.35% | Equal-weighted; gives meaningful allocation to second-tier and specialty companies; often provides different return profile from ITA due to equal-weighting and sub-sector mix |
| Global X Defense Tech ETF | SHLD | Global X Defense Tech Index | Palantir, CACI, Leidos, General Dynamics, L3Harris | 0.50% | Tilts toward defense technology, cybersecurity, and intelligence services; less commercial aviation exposure; good complement to ITA for investors emphasizing the IT/cyber defense sub-segment |
How to Evaluate Defense Stocks
Defense stocks require specific metrics that are largely irrelevant to consumer or technology stock analysis. The government-contract-dominated business model creates a distinct analytical framework.
1. Backlog — the Single Most Important Leading Indicator
In defense, a company's backlog (the value of contracts awarded but not yet executed) is the primary forward revenue indicator. A growing backlog signals increasing future revenue and government confidence in the contractor. Northrop Grumman's 2025 backlog exceeded $95 billion — representing roughly three years of annual revenue in future contracts already awarded. Investors should look not just at total backlog, but at the growth rate of backlog quarter-over-quarter and whether the mix is shifting toward higher-margin programs.
2. Book-to-Bill Ratio
The book-to-bill ratio compares new contract awards ("bookings") received in a period against revenue recognized ("billings") in that same period. A ratio above 1.0 means the company is winning new work faster than it is delivering on existing work — a positive signal for future growth. A ratio consistently below 1.0 suggests backlog depletion and potential future revenue softness. This metric is less relevant for companies with multi-decade program positions (like Northrop's B-21) but highly relevant for service and IT contractors where contract renewals are more frequent.
3. Program Mix: Cost-Plus vs. Fixed-Price Contracts
Cost-plus contracts allow the government to reimburse the contractor's actual costs plus an agreed profit fee — they limit financial risk on development programs but cap margin upside. Fixed-price contracts lock the price regardless of actual costs — they offer margin upside if costs come in below estimate, but expose the contractor to losses if costs overrun (a significant risk on development programs, as Boeing's defense division has demonstrated). Investors should understand a company's contract mix when assessing earnings quality and risk.
4. Free Cash Flow Conversion
Defense companies are capital-intensive but should generate strong free cash flow (FCF) relative to net income over a program cycle. FCF conversion (FCF divided by net income) above 100% is a positive indicator. Be cautious of defense companies citing earnings improvement while FCF remains persistently below net income — this can signal aggressive revenue recognition on long-term contracts or investment cycles that will require future capital.
5. International Revenue and Export Licenses
For large prime contractors, international defense sales through Foreign Military Sales (FMS) programs or Direct Commercial Sales (DCS) can represent significant and growing revenue. Countries are expanding defense procurement, and U.S. prime contractors with approved export licenses for high-demand systems (Patriot batteries, F-35s, AH-64 Apaches) have meaningful international growth catalysts beyond the U.S. defense budget alone.
6. Dividend Consistency and Capital Return
Established defense prime contractors are known for long dividend growth histories. Lockheed Martin and Northrop Grumman have multi-decade track records of dividend increases. Consistent dividend growth signals management confidence in long-term earnings stability — appropriate for the defense sector's steady, government-contract revenue base. Investors evaluating defense stocks as income-generating instruments should review dividend payout ratios and historical growth rates.
Risks of Investing in Defense Stocks
While the defense sector's government-contract revenue base provides a degree of stability absent in most sectors, materially significant risks apply that every investor must understand.
Defense Budget Sequestration and Continuing Resolutions (CRs)
The U.S. federal government operates under Congress-approved annual defense budgets. When Congress fails to pass an annual appropriations bill on time, the government operates under a Continuing Resolution (CR) — which typically restricts new contract starts and limits spending to prior-year levels. Prolonged CRs or, in the extreme case, budget sequestration (automatic across-the-board cuts as occurred in 2013) can create significant near-term disruption to contract awards. The defense budget is not inflation-proof: real defense spending can effectively decline if inflation in labor and materials outpaces the nominal budget increase.
Program Cancellation Risk
Even very large, advanced defense programs can be cancelled or significantly restructured due to shifting strategic priorities, cost overruns, or political dynamics. Boeing's KC-46 tanker program has suffered billions in cost overruns; the Army's cancelled Future Combat Systems program represented a massive investment write-off. Fixed-price development programs carry the greatest risk of significant losses when technical complexity exceeds original estimates.
Concentration and Program Dependency
Many defense companies generate a substantial share of revenue from a single program or a small number of large programs. Lockheed Martin's F-35 represents approximately 25–30% of its annual revenue — making production rate adjustments, export license delays, or rate changes on that single program a significant earnings driver. Investors in individual defense companies should carefully assess program concentration and what a production rate reduction or cancellation in a key program would mean for earnings.
Fixed-Price Development Contract Risk
Defense companies bidding on development contracts at fixed prices bear all cost overrun risk. This has been catastrophic for Boeing's defense division in multiple programs (KC-46, T-7 Red Hawk trainer), generating billions in cumulative write-downs. When a company wins a large fixed-price development award and begins reporting program charges, investors should carefully assess the realistic likelihood of additional charges before the program reaches production.
Ethical and ESG Considerations
Some institutional and individual investors avoid defense stocks based on ethical concerns about investing in companies that profit from weapons and military conflict. Investors should be aware that an increasing number of ESG (Environmental, Social, and Governance) funds and screening products exclude defense stocks. This creates a structural headwind for defense sector valuations relative to what they might otherwise command from a pure earnings perspective — though the magnitude of that effect is debated.
Geopolitical Peace Risk ("Peace Dividend" Scenario)
Defense budgets historically compress during periods of reduced global tension — as occurred after the Cold War ended and in the 2010s after the drawdown from Iraq and Afghanistan. If current geopolitical tensions meaningfully de-escalate — through a Ukraine ceasefire, Middle East stabilization, or bilateral agreements on military spending — defense budgets could face pressure, and the premium multiple investors have recently assigned to the sector could partially reverse. This is a low-probability near-term scenario in 2026 but represents the relevant macro downside case.
Defense Stocks vs. ETFs: Which Fits Your Portfolio?
| Consideration | Individual Defense Stocks | Defense ETFs |
|---|---|---|
| Return Potential | Higher — specific program wins, backlog growth, or margin expansion can drive significant outperformance vs. sector | Sector average — captures the broad defense spending tailwind without single-company alpha |
| Risk Level | Moderate to High — program cancellation, contract charges, or budget exposure can cause significant individual stock drawdown | Moderate — single-company setbacks are diluted across 20–60+ holdings |
| Research Required | Intensive — requires understanding of program mix, contract types, budget exposure, backlog composition, and competitive position | Moderate — fund holdings review, index methodology, commercial aerospace exposure level |
| Defense Purity | High — can select pure-play defense names (e.g., NOC, LHX) with minimal commercial exposure | Variable — most ETFs include commercial aerospace companies; check holdings before assuming "pure" defense exposure |
| Income / Dividends | Prime contractors (LMT, NOC, GD) are consistent dividend growers; second-tier varies | ETFs distribute dividends from underlying holdings; often less consistent growth than buying individual dividend-growing primes |
| Cost | No management fee; trading costs only | 0.35–0.57% annual expense ratio for non-leveraged defense ETFs |
| Best For | Investors with specific conviction in particular programs, management teams, or industry sub-segments — backed by deep sector research | Investors seeking defense sector exposure as a portfolio diversifier or geopolitical hedge without company-level research commitment |

Key Takeaways: Defense Stocks in 2026
- Defense stocks are not a monolith: Prime contractors, second-tier suppliers, defense technology companies, and emerging platform developers each behave differently. Knowing which sub-segment you are buying is the essential first step.
- Government is the customer — understand what that means: Revenue stability comes from multi-year procurement contracts, not consumer demand. But it also means program concentration risk, contract type risk, and budget appropriation cycles are the relevant variables to monitor — not quarterly consumer sentiment data.
- Backlog is your primary leading indicator: In defense, backlog growth or compression is the most forward-looking business signal available. Always review backlog alongside reported revenues.
- The book-to-bill ratio signals future revenue momentum: Consistently above 1.0 means new work is growing faster than delivery; below 1.0 for multiple quarters is a warning signal for future revenue.
- Fixed-price development contracts carry asymmetric risk: They can underperform relative to cost-plus contracts when technical complexity surprises. Boeing's defense losses are the most visible recent example. Understand a company's contract mix before assessing earnings quality.
- Geopolitics create cyclical tailwinds — not permanent ones: Defense stocks have re-rated materially higher over the past two years. The current premium reflects a strong budget environment. A reversal in geopolitical conditions could compress valuations even if earnings remain stable.
- ETFs offer sector exposure with less company-level risk: ITA, PPA, and XAR each have different holdings profiles. For investors without deep defense sector expertise, an ETF is a more calibrated approach than concentrated prime contractor positions.
- Consider commercial aviation contamination in your ETF: Most "defense ETFs" include Boeing and GE Aerospace — companies with major commercial aviation businesses. If your thesis is pure defense, verify your ETF doesn't dilute it with commercial aerospace exposure.
Frequently Asked Questions About Defense Stocks
Aerospace stocks refer broadly to companies involved in aircraft and spacecraft design, manufacturing, and operations — which includes both commercial aviation (airlines, commercial jet manufacturers) and military aviation. Defense stocks more specifically refer to companies whose revenue is primarily derived from military and national security contracts with governments. Many companies — including RTX, Boeing, and GE Aerospace — operate in both segments simultaneously, making their equity performance a blend of commercial aviation demand and defense budget cycles. Pure defense exposure requires selecting companies with high defense revenue percentages, such as Lockheed Martin, Northrop Grumman, or L3Harris.
Defense stocks are often described as having countercyclical or non-cyclical characteristics because defense budgets are set by Congressional appropriations rather than consumer demand — meaning revenue from long-term government contracts typically does not decline during economic downturns the way consumer-facing businesses do. Historically, defense stocks have tended to hold their value better during broad market downturns relative to more economically sensitive sectors. However, "recession-proof" is an overstatement — budget sequestration (as in 2013), changes in administration, and shifts in appropriations priorities can still affect defense contractor revenues and stock prices.
The answer depends on what type of defense exposure you want. ITA (iShares U.S. Aerospace & Defense) is the largest by assets and most liquid, but is market-cap weighted and includes significant commercial aerospace names. PPA (Invesco) uses a modified equal-weight approach and includes defense IT and services companies. XAR (SPDR) is equal-weighted and tilts more meaningfully toward second-tier and specialty companies often underrepresented in ITA. SHLD (Global X Defense Tech) focuses more on defense technology, cyber, and intelligence services. Investors should review current fund holdings directly before purchasing, as compositions change over time.
Many of the largest U.S. defense prime contractors are consistent dividend payers with long histories of annual dividend increases. Lockheed Martin, Northrop Grumman, General Dynamics, and RTX Corporation all pay regular quarterly dividends and have multi-decade track records of dividend growth — reflecting the stable, long-duration cash flow characteristics of government contract revenues. Not all defense companies pay dividends — second-tier specialists, defense technology companies, and smaller emerging defense platform developers may reinvest cash into growth rather than returning it as dividends. Income-focused investors should verify current dividend policy, payout ratio, and historical growth rate before making any investment decision.
The U.S. Department of Defense budget is one of the most significant fundamental drivers for defense sector revenues. A higher budget — particularly one that grows faster than prior years — provides funding for new program starts, increased production rates on existing platforms, and expansion of services contracts. The budget's composition (how much goes to procurement vs. R&D vs. operations and maintenance) matters as much as the total number. Congressional authorization and appropriation of each year's defense budget can cause temporary disruptions through Continuing Resolutions. Investors monitor the President's budget request, Congressional markup, and final appropriations to anticipate contract award volumes.
A cost-plus contract (or cost-reimbursement contract) is a government contract type where the government agrees to pay the contractor's actual allowable costs plus an additional fee (the "plus") representing profit. These contracts are typically used for development programs where the technical complexity makes it difficult to estimate costs accurately upfront — the government assumes cost risk in exchange for cost transparency and oversight. From an investor perspective, cost-plus contracts provide revenue stability and limit the risk of major losses but also cap potential margin upside compared to fixed-price contracts where the contractor keeps the profit from performing under a fixed price.
"War stocks" is a colloquial term for defense and military-related stocks that may benefit from increased defense spending during periods of armed conflict or geopolitical escalation. While it is accurate that geopolitical events often trigger near-term rallies in defense stocks, making investment decisions based solely on a single geopolitical event carries significant risk — these short-term price movements often reverse or are already priced in by the time retail investors act on them. The more durable investment framework for defense stocks focuses on long-term budget trends, backlog levels, and program visibility — not on day-trading news-driven spikes around specific military events.
Whether investing in defense stocks aligns with one's personal values is an individual decision that varies based on ethical frameworks, beliefs about national security, and perspectives on the role of military capability in maintaining peace. Some investors actively exclude defense companies from their portfolios based on ethical concerns about profiting from weapons and conflict; others argue that strong domestic defense industries are essential for national security and deterrence. From an investment perspective, investors should be aware that ESG (Environmental, Social, and Governance) fund screening increasingly excludes defense stocks, which may create marginal valuation differences relative to companies with similar financial characteristics in other sectors. This is a personal values question, not a financial investment advice question, and one that individual investors and advisors should discuss based on the investor's own values and circumstances.
