Screening Filters
Market Cap ≥ $2 billion & Market Cap Category: Mega / Large / Mid
- Purpose: Focus on established, sizable copper-related companies rather than tiny, speculative miners.
- Rationale:
- When someone asks for the “best” copper stock, they usually mean a company with scale, liquidity, and business stability—not a micro-cap exploration play.
- Requiring market cap ≥ $2B automatically excludes very small, higher-risk companies that can be extremely volatile and harder to analyze.
- Restricting to mega, large, and mid caps reinforces this by keeping the universe to more mature, better-followed companies, which also tend to have better governance and reporting quality.
Exchange: XNYS (NYSE) and XNAS (NASDAQ)
- Purpose: Ensure the stocks are listed in the United States, matching the user’s request.
- Rationale:
- NYSE and NASDAQ are the primary U.S. stock exchanges.
- Limiting to these exchanges gives you U.S.-listed copper or diversified miners, which are accessible to most U.S. investors and subject to U.S. regulatory and reporting standards.
Industry: Metals & Mining
- Purpose: Narrow the universe to mining and metals companies, which is where copper producers and copper-focused miners sit.
- Rationale:
- “Best copper stock” naturally points to copper miners, diversified miners, or metals producers.
- While the filter is at the broader Metals & Mining level (not “copper only”), this is the correct sector to find copper-exposed names. Many major copper players are classified as diversified miners with multiple metals, but copper is a key part of their revenue mix.
Return on Equity (ROE) ≥ 8%
- Purpose: Focus on miners that are reasonably profitable and efficient at generating returns for shareholders.
- Rationale:
- In a capital-intensive business like mining, a minimum ROE ≥ 8% helps weed out chronically unprofitable or poorly run companies.
- A stock being “best” is not just about copper exposure; it should also be able to convert that exposure into solid shareholder returns over time.
Debt-to-Equity ≤ 1.5
- Purpose: Avoid miners with excessive leverage, which can be dangerous in a cyclical commodity industry like copper.
- Rationale:
- Copper prices are volatile. Over-levered miners can get into serious trouble when prices fall.
- By capping debt/equity at 1.5, the screener attempts to select companies with more manageable balance sheets, improving resilience across the commodity cycle and lowering bankruptcy or severe dilution risk.
Quarterly Revenue YoY Growth ≥ 0.01% (0.0001 as a decimal)
- Purpose: Prefer companies with at least non-negative, ideally positive, top-line momentum.
- Rationale:
- This filter effectively removes companies with clearly shrinking revenue versus the same quarter last year.
- For a “best” candidate, you generally want miners that are at least maintaining or growing revenue—through higher production, better pricing, or acquisitions—rather than those in clear decline.
Why Results Match the User’s Request
- The U.S. exchange filter (NYSE/NASDAQ) directly aligns with “in the United States.”
- The Metals & Mining industry filter is the right sector to capture copper producers and diversified miners with significant copper exposure.
- The size (market cap) filters steer the search toward more established, liquid names that are realistically in the conversation for “best” rather than thinly traded speculative plays.
- The ROE, debt/equity, and revenue growth filters collectively aim to identify financially healthier, better-managed, and at least modestly growing companies—key qualities when judging what might be the “best” copper-related stock, not just any copper stock.
In other words, these filters don’t guarantee the single best copper stock, but they construct a focused list of larger, U.S.-listed, copper-related miners with decent profitability, manageable leverage, and non-deteriorating revenue, which is a rational starting universe for picking a “best” candidate.
