Return on Equity (ROE) Filter: Finding Capital-Efficient Businesses
What ROE measures, what a good ROE looks like, and why high-ROE stocks tend to be more resilient assignment candidates for wheel traders.
What is ROE?
ROE = Net Income ÷ Shareholders' Equity × 100
Return on Equity (ROE) measures how much profit a company generates for each dollar of equity shareholders have invested. A 20% ROE means the business earns $0.20 for every $1 of book equity — a benchmark many professional investors consider the minimum for a quality business.
Warren Buffett famously looks for companies that sustain 15–20%+ ROE for many years running.
Why ROE matters for wheel traders
When you're assigned a CSP, you're now a shareholder. You want to own a company that:
- Earns strong returns on the capital it deploys.
- Doesn't need to issue dilutive equity to fund operations.
- Has a durable competitive advantage (moat) supporting those returns.
High and sustained ROE is one of the best single indicators of a company having exactly those qualities.
Recommended thresholds
| ROE | Signal |
|---|---|
| < 8% | Below par; question the capital allocation |
| 10–15% | Decent; acceptable in capital-intensive sectors |
| 15–25% | Good; indicates a strong competitive position |
| > 25% | Excellent — but verify it isn't fuelled by excessive debt |
The debt caveat
ROE can be inflated by taking on debt (leverage reduces the equity denominator). A 40% ROE with a D/E of 5 is not the same as a 25% ROE with a D/E of 0.5.
Always combine the ROE filter with a maximum D/E ratio (try 1.5) to ensure the return is genuine, not leveraged.
Using the filter
- Open the Stock Screener.
- Find ROE in the Profitability section.
- Set minimum to 12%.
- Set D/E maximum to 1.5 in the Valuation section.
- Optionally add 5Y ROE minimum to confirm the track record.
A worked example: Quality Growth screen
- Market Cap ≥ 5B
- ROE ≥ 15%
- Net Margin ≥ 10%
- D/E ≤ 1.5
- 5Y EPS Growth ≥ 8%
This combination reliably surfaces 40–80 high-quality US businesses — exactly the sort of stocks experienced wheel traders want in their rotation.
Frequently Asked Questions
What is a good ROE for wheel strategy stocks?
Most wheel traders target ROE ≥ 15%, though 12% is acceptable in capital-intensive sectors like utilities or manufacturing. Pair ROE with a D/E cap to make sure the return isn't manufactured by leverage.
Why does high ROE sometimes indicate high risk?
Extreme ROE (> 50%) often means the company has bought back so much stock that book equity is tiny, or it has very high debt. In both cases the equity cushion protecting you as an assigned shareholder is thin. Always check D/E alongside ROE.
