| 15 | |
| 16 | ## Do Not Use When |
| 17 | |
| 18 | - Another skill fits better. |
| 19 | - Critical data for this model is missing. |
| 20 | - The user wants guaranteed returns or unbounded leverage. |
| 21 | - The request is generic chatter with no decision. |
| 22 | |
| 23 | ## Inputs Needed |
| 24 | |
| 25 | - Asset, sector, market, or macro context |
| 26 | - Relevant financial, technical, policy, or sentiment data |
| 27 | - Time horizon and risk constraints |
| 28 | - Portfolio context if sizing is requested |
| 29 | |
| 30 | ## Process |
| 31 | |
| 32 | 1. Ask: do I understand this business? If not, stop. |
| 33 | 2. Judge: is it a good business? Moat, pricing power, durable economics. |
| 34 | 3. Check: is the price right? Is there margin of safety? |
| 35 | 4. Verify: is management honest and aligned? |
| 36 | 5. Decide: if all pass, own it and hold. If any fails, pass. |
