Overview

Warren Buffett-lens scorecard for any ticker. Scores 4 dimensions 0-100 each (business / circle of competence, moat / durable advantage, management / capital allocation, valuation / fair price vs 10Y treasury) and returns a weighted overall HOLDABLE / WATCHABLE / AVOID verdict. This is NOT a generic fundamental screener — it's Buffett's specific framework mechanically applied: sector simplicity, gross margin + ROE + profit margin thresholds, FCF yield vs treasury, and dividend-continuity as management proxy. Triggers: "Buffett analysis AAPL", "score KO with Buffett lens", "would Buffett buy MSFT", "JNJ Buffett scorecard", "AAPL moat analysis", "fair price vs bonds", "Buffett-style verdict on NVDA", "long-term hold analysis"

AlphaGBM Buffett Analysis

The 4 lenses Buffett himself says he applies, computed from yfinance fundamentals and returned as a single-number verdict plus reasoning for each lens.

The 4 Lenses

Business (20% weight) — circle of competence. Simple sectors (consumer staples, utilities, industrials) score high. Complex sectors (tech, healthcare, financials) score lower unless mega-cap like AAPL.
Moat (30% weight) — durable advantage. Gross margin > 40%, ROE > 20%, profit margin > 15%, and market cap > $100B each contribute to the moat score.
Management (15% weight) — capital allocation proxy via dividend continuity
- payout ratio (15-60% is ideal balance) + 5yr avg div yield.
Valuation (35% weight) — fair price check. PE < 15 → +20, PEG < 1 → +15, FCF yield > 10Y treasury + 2pp → +20. PE > 40 or PEG > 2.5 → deductions.

Overall Verdict

≥ 75 → HOLDABLE (color green) — meets Buffett standards, long-term hold
55-74 → WATCHABLE (color amber) — wait for better price or clearer evidence
< 55 → AVOID (color red) — fails Buffett's standards

Why This Is a Separate Skill

The generic alphagbm-stock-analysis runs a G=B+M style/momentum score. Buffett's framework is different — it weights moat + valuation much more heavily than momentum, and penalizes complex businesses regardless of growth. This skill codifies Buffett's rules, not AlphaGBM's house rules.

How to Use

Input:

ticker (required) — US stock symbol

Output:

scorecard.business: {score, sector, industry, verdict_zh, verdict_en}
scorecard.moat: {score, gross_margin, roe, profit_margin, market_cap_b, reasons_zh, reasons_en}
scorecard.management: {score, dividend_rate, payout_ratio, reasons_zh, reasons_en}
scorecard.valuation: {score, pe, forward_pe, peg, pb, fcf_yield_pct, ten_year_treasury, reasons_zh, reasons_en}
scorecard.overall: {score, verdict, verdict_zh, verdict_en, color}

Example Queries

Buffett analysis on KO → likely HOLDABLE (simple business, strong moat, 30+ year hold by Buffett himself)
would Buffett buy NVDA → likely WATCHABLE or AVOID (complex sector, high valuation)
Buffett scorecard JNJ → likely HOLDABLE (consumer defensive, strong margins, reasonable PE)
score AAPL with Buffett lens → reference Berkshire's own holding for context
apply Buffett's checklist to WMT → retail-native test case

# AlphaGBM Buffett Analysis

The 4 lenses Buffett himself says he applies, computed from yfinance fundamentals
and returned as a single-number verdict plus reasoning for each lens.

## The 4 Lenses

1. **Business (20% weight)** — circle of competence. Simple sectors (consumer
   staples, utilities, industrials) score high. Complex sectors (tech, healthcare,
   financials) score lower unless mega-cap like AAPL.
2. **Moat (30% weight)** — durable advantage. Gross margin > 40%, ROE > 20%,
   profit margin > 15%, and market cap > $100B each contribute to the moat score.
3. **Management (15% weight)** — capital allocation proxy via dividend continuity
   + payout ratio (15-60% is ideal balance) + 5yr avg div yield.
4. **Valuation (35% weight)** — fair price check. PE < 15 → +20, PEG < 1 → +15,
   FCF yield > 10Y treasury + 2pp → +20. PE > 40 or PEG > 2.5 → deductions.

## Overall Verdict

- **≥ 75** → HOLDABLE (color green) — meets Buffett standards, long-term hold
- **55-74** → WATCHABLE (color amber) — wait for better price or clearer evidence
- **< 55** → AVOID (color red) — fails Buffett's standards

## Why This Is a Separate Skill

The generic `alphagbm-stock-analysis` runs a G=B+M style/momentum score. Buffett's
framework is different — it weights moat + valuation much more heavily than
momentum, and penalizes complex businesses regardless of growth. This skill
codifies *Buffett's* rules, not AlphaGBM's house rules.

## How to Use

**Input:**
- `ticker` (required) — US stock symbol

**Output:**
- `scorecard.business`: `{score, sector, industry, verdict_zh, verdict_en}`
- `scorecard.moat`: `{score, gross_margin, roe, profit_margin, market_cap_b, reasons_zh, reasons_en}`
- `scorecard.management`: `{score, dividend_rate, payout_ratio, reasons_zh, reasons_en}`
- `scorecard.valuation`: `{score, pe, forward_pe, peg, pb, fcf_yield_pct, ten_year_treasury, reasons_zh, reasons_en}`
- `scorecard.overall`: `{score, verdict, verdict_zh, verdict_en, color}`

## Example Queries

- `Buffett analysis on KO` → likely HOLDABLE (simple business, strong moat, 30+ year hold by Buffett himself)
- `would Buffett buy NVDA` → likely WATCHABLE or AVOID (complex sector, high valuation)
- `Buffett scorecard JNJ` → likely HOLDABLE (consumer defensive, strong margins, reasonable PE)
- `score AAPL with Buffett lens` → reference Berkshire's own holding for context
- `apply Buffett's checklist to WMT` → retail-native test case
