Quality Compounder framework, explained
IN THE TRADITION OF MODERN QUALITY-COMPOUNDING RESEARCH
Quality Compounder looks for businesses that earn persistently high returns on invested capital and can keep reinvesting at those rates. The compounding case rests on durability, so the screen asks for returns that held across years rather than one strong one, and the filing read looks for the moat, reinvestment runway and governance behind them.
What it looks for
ROIC persistence across years, a gross-margin floor, cash conversion, and share-count and stock-pay discipline.
The moat evidence behind the returns, reinvestment runway in the business description, and capital-allocation discipline in MD&A.
The quantitative screen looks for return on invested capital that persisted across years, healthy gross margins, earnings that convert to cash, and limited dilution from new shares and stock-based pay.
The AI read examines what drives the returns, the evidence of a moat, earnings quality, capital allocation, integrity in governance and disclosure, how the company innovates and adapts, and valuation context. It reads the notes on revenue recognition and stock-based compensation, because both can flatter returns.
Filings it reads
Citations name the sections they rely on from these filings. Anything they do not disclose is marked unknown rather than inferred. Where a company puts its MD&A and financial statements in its annual report to shareholders instead of the 10-K, that report is read too.
| What is read | Why this framework reads it |
|---|---|
| 10-K: Business (Item 1) | What the company sells, to whom, and how it competes. |
| 10-K: Risk factors (Item 1A) | The risks the company itself says are material. |
| 10-K: MD&A (Item 7) | Management’s explanation of what drove the results. |
| 10-K: Financial statements and notes (Item 8) | The audited numbers the rest of the read is checked against. |
| 10-K notes: segments, goodwill, revenue recognition and stock-based compensation | The accounting choices that can make returns look higher than they are. |
| Proxy statement: executive pay, related-party transactions and board composition | Governance and integrity evidence. |
| Recent 8-Ks: results (Item 2.02) and officer or director changes (Item 5.02) | Recent results and leadership changes since the 10-K. |
| Earlier 10-Ks, for the multi-year record | Whether high returns persisted across years. |
What each verdict means
A verdict describes how well a company’s filings fit this framework, as of the filings read. It is never a prediction and never an action to take.
- GEMSTONE
- The filings show high returns that persisted, a moat that explains them, room to reinvest and sound governance.
- GEODE
- The returns are there, but the moat, the reinvestment runway or governance is mixed or unverifiable.
- SEDIMENT
- The returns are not durable, depend on accounting choices, or come with governance problems the filings disclose.
When the filings cannot support any verdict, none is issued: the company is shown as Not scored.
What this framework misses
- Persistently high returns are a record of the past. A durable-looking moat can still be disrupted by something the filings have not yet mentioned.
- Compounders are often highly valued. Valuation is read as context, and the verdict does not say whether the price is reasonable.
- Stock-based compensation and acquisitions can obscure returns. The read checks the notes, but disclosure varies across companies.
