Overview

Memo Maker scores stocks with a transparent 10-point checklist (TRP-1) and optionally runs a tiny event study (T-1..T+3) vs. SPY for context.

TRP-1 checklist (0–10)

1. Business quality
2. Financial quality
3. Risk / leverage
4. Valuation sanity
5. Unit economics / margins
6. Growth durability (LTM → 3y)
7. Cash generation / FCF
8. Competitive moat / switching costs
9. Management & incentives
10. Narrative consistency & evidence

Each “yes” = 1 point. In memos, note brief support for each item.

Event study (optional)

• Pick an event date (e.g., earnings).
• Compute simple returns for Stock and SPY on T-1, T0, T+1, T+2, T+3.
• Abnormal = Stock − SPY.
• Report the table; no inference is implied.

Reproducibility

• Data: 10-K/10-Q, transcripts, IR; prices via yfinance.
