Can I invest in war?

Screening Filters

1. Market Cap ≥ $5,000,000,000

   • Purpose: Focus on larger, more established defense companies.
   • Rationale:
     • When you ask “Can I invest in the defense sector?”, you’re usually thinking about recognizable, stable names rather than tiny, speculative firms.
     • A $5B+ market cap threshold screens out micro/small caps that tend to be much more volatile and riskier, and keeps you in the realm of companies with established contracts, diversified revenue, and better access to financing.

2. Beta: LowRisk or ModerateRisk

   • Purpose: Limit the list to stocks with historically lower or moderate volatility compared to the overall market.
   • Rationale:
     • Defense can be cyclical and politically sensitive. By restricting to low/moderate beta, the screener is aligning with a more “investor” rather than “speculator” profile.
     • This fits someone asking broadly “Can I invest in the defense sector?” rather than “What are the riskiest, most explosive defense stocks?”

3. PriceAboveMA200 (Price above 200-day moving average)

   • Purpose: Include only stocks that are in a longer-term uptrend or at least not in a prolonged downtrend.
   • Rationale:
     • The 200-day moving average is a common technical indicator for long-term trend. If price is above this line, the stock is generally considered to be in a positive or stable trend.
     • For someone considering entering the sector now, this avoids names that are currently under heavy selling pressure or in technical breakdowns.

4. Industry: Aerospace & Defense

   • Purpose: Directly target the defense sector.
   • Rationale:
     • This is the core filter that aligns with your question. “Defense sector” in stock screening terms maps most closely to the “Aerospace & Defense” industry classification.
     • It captures defense contractors, weapons systems makers, aerospace/defense tech, and related service providers.

5. Region: US

   • Purpose: Restrict results to companies based in or primarily listed in the United States.
   • Rationale:
     • Many investors asking about “the defense sector” are implicitly thinking of major US defense contractors (Lockheed Martin, Raytheon, Northrop Grumman, etc.).
     • US defense names are tightly linked to the large and relatively stable US defense budget, and they tend to have better disclosure, liquidity, and analyst coverage compared with many international peers.

6. Net Margin ≥ 5%

   • Purpose: Ensure the companies are at least reasonably profitable.
   • Rationale:
     • A positive and decent net margin filter removes chronically unprofitable or barely-break-even firms, which are riskier and more sensitive to contract timing.
     • For a general “Can I invest in this sector?” inquiry, it makes sense to focus on companies that demonstrate the ability to convert revenue into actual earnings, especially in a contract-driven industry like defense.

Why Results Match Your Question

• You asked about investing in the defense sector, not trading highly speculative defense names. The filters tilt toward:

  • Larger, more established companies (market cap ≥ $5B),
  • With controlled risk (low/moderate beta),
  • In reasonably strong trends (price above 200-day MA),
  • And solid profitability (net margin ≥ 5%).

• By narrowing to US Aerospace & Defense firms, the screener aligns directly with the commonly understood “defense sector” and focuses on names likely to be accessible, liquid, and well-covered for an individual investor evaluating whether to allocate capital to this theme.
