Read through an investor’s lens

|---|---|---|
| Warren Buffett | Owner earnings, return on equity, and as little debt as possible. | 4 |
| Terry Smith | Return on capital first, then cash conversion, then leave it alone. | 4 |

| Chuck Akre | High returns on equity, earned without leverage, with somewhere to reinvest them. | 3 |
| Philip Fisher | Margins, and what the company is doing to defend them. | 3 |
| Walter Schloss | Start from book value, avoid leverage, and let the balance sheet decide. | 2 |
| Benjamin Graham | Solvency first, and a published number for every test. | 2 |
| Joel Greenblatt | Two numbers only: what the business earns on its capital, and what you get for the price. | 1 |
| Peter Lynch | Balance sheet first, then growth against the price. | 2 |

9 published methods. The overlap is the finding: return on capital and leverage appear in most of them, and no two agree on the full set.
What is not here, and why
| P/E, P/B, EV/EBITDA, dividend yield | Every one needs a share price, which is licensed data. Nothing here holds one — instead every company page computes these in your browser against a price you type. Why, and what you get. |
|---|---|
| Analyst targets, ratings, sentiment | Opinions rather than filings. Nothing here is derived from them. |
| Adjusted or non-GAAP earnings | Used only where the industry has no alternative — funds from operations for REITs — and labelled an approximation where it is. |
