Defense stocks

Screening Filters

1. Industry: ['Aerospace & Defense']

   • Purpose: Limit results to companies directly in the defense sector.
   • Rationale: Your question is specifically about “defense sector stocks.” The primary publicly traded defense names are classified under Aerospace & Defense, which includes contractors, weapons systems manufacturers, defense technology providers, and related support firms. This filter cuts out unrelated sectors (e.g., tech, retail, banks) and focuses only on businesses whose core revenues come from defense-related activities.

2. Market Capitalization: min 1,000,000,000 (≥ $1B)

   • Purpose: Focus on larger, more established defense companies.

   • Rationale: When you ask which stocks are “worth analyzing or investing in,” it’s often more useful to start with companies that:

     • Have proven business scale and track records
     • Tend to have better liquidity (easier to buy/sell)
     • Are generally less fragile than very small micro-cap names

     A $1B+ market cap threshold screens out the smallest, riskiest defense plays and centers the search on mid-cap and large-cap companies, which are more typical investment candidates for most investors.

3. Exchange Listing: ['XNYS', 'XNAS'] (NYSE and NASDAQ)

   • Purpose: Include only major US-listed stocks.

   • Rationale: NYSE and NASDAQ are the primary US exchanges with:

     • Strong listing standards (reporting, governance, etc.)
     • High liquidity and tighter bid/ask spreads
     • Better analyst coverage and data availability

     For someone looking for “worth analyzing or investing,” focusing on these exchanges makes it easier to research the companies and trade them efficiently, and filters out less-regulated or illiquid markets.

4. Net Margin: min 5 (≥ 5%)

   • Purpose: Ensure companies have at least a baseline level of profitability.

   • Rationale: Net margin measures how much profit a company keeps from each dollar of revenue. A minimum of 5%:

     • Excludes chronically unprofitable or barely breakeven firms
     • Prioritizes defense companies that are actually converting revenue into earnings

     For long-term investing, consistently profitable firms are generally more attractive and better positioned to weather contract cycles or budget changes.

5. Return on Equity (ROE): min 8 (≥ 8%)

   • Purpose: Focus on companies that use shareholder capital efficiently.

   • Rationale: ROE shows how effectively a company generates profit from shareholders’ equity. A minimum of 8%:

     • Filters out underperformers that destroy or barely grow shareholder value
     • Highlights defense firms with stronger management, competitive positions, or more profitable contracts

     For investors, higher ROE often correlates with better quality businesses and more sustainable competitive advantages.

6. P/E (Price/Earnings) TTM: min 8, max 35

   • Purpose: Screen for reasonably valued, not-extreme defense stocks.

   • Rationale: The P/E ratio compares price to current earnings:

     • Minimum of 8: Avoids ultra-low P/E names that might be “value traps” (priced low because the market expects serious problems) or distorted by one-off earnings spikes.
     • Maximum of 35: Excludes extremely expensive stocks where expectations may be overly optimistic and downside risk is higher if growth disappoints.

     Together, this range aims to find defense stocks that are neither dirt-cheap for potentially bad reasons nor priced at speculative extremes.

Why Results Match Your Question

• You asked about defense sector stocks, so the Aerospace & Defense industry and NYSE/NASDAQ listing filters make sure you’re seeing mainstream, investable defense names rather than peripheral or hard-to-trade companies.
• You wanted stocks “worth analyzing or investing in,” so the market cap, net margin, and ROE filters collectively emphasize:
  • Established companies over tiny, speculative plays
  • Businesses that are currently profitable
  • Firms that generate reasonable returns on shareholder capital
• The P/E range filter adds a basic valuation discipline, focusing on defense stocks that are not obviously priced at unrealistic extremes, making them more reasonable candidates for further, deeper analysis.
