## 🎯 Screening & Ranking Methodology

Plan B follows a strict **Graham–Klarman–Buffett** deep-value discipline (excluding financials SIC 6000–6799).

| Pillar | Hard Quantitative Gate (must pass all 3 simultaneously) |
| :--- | :--- |
| **Cheap** | `P/E ≤ 12` **or** `EV/EBIT ≤ 8` **or** `NCAV / Market Cap ≥ 1.0` (Benjamin Graham net-net) |
| **Safe** | Positive equity, `current_ratio ≥ 1.2`, `liabilities ≤ 2.0× equity` (or net cash), `3Y dilution ≤ 25%`, and `CFO > 0` if `NI < 0` |
| **Hated** | Price down ≥ **40%** from 3-year weekly high (`dd_3y ≤ -0.40`), `Market Cap ≥ $50M`, `Price ≥ $1.00` |

<details>
<summary><b>Composite Score Formula (0–100), Bonuses, Penalties & AI Adjustment</b></summary>

- **Base Weighting:** 40% **Cheap** (`cheap_score`) + 30% **Safe** (`safe_score`) + 30% **Hated** (`hated_score`, blending price drawdown and headline negativity `news_neg`).
- **Bonuses:** Net open-market Form 4 insider buying (up to +12 pts), same-day cluster buying, and 3-year share count reduction via buybacks (+4 pts).
- **Penalties:** Share dilution, negative free cash flow, accrual divergence, one-off profits following loss years, high goodwill/M&A intensity, and elevated off-exchange short-volume pressure.
- **AI 10-K Adjustment:** After reading the 10-K/20-F filing, the composite score is adjusted by the AI analyst's verdict (`CONTRARIAN BUY CANDIDATE`, `WATCH`, or `AVOID`) and conviction (`0–100`).

## 🛡️ Data Integrity, Privacy & Caveats

- **Zero Credentials / Zero PII Guarantee:** Every export passes an automated security gate (`assertNoCredentials`) that enforces an explicit column allowlist, scrubs email addresses, and scans against secret/token patterns before writing or uploading.
- **XBRL Tagging Nuances:** SEC fundamentals reflect company-reported US-GAAP XBRL tags. Unusual tagging or dual-class share structures can occasionally distort market cap or debt ratios; always cross-check the linked SEC filing (`tenk_url`).
- **Research Only:** This dataset is for quantitative, academic, and machine-learning research only and never constitutes financial or investment advice.
