jp-stock-fundamental-screen

name: jp-stock-fundamental-screen description: Run the weekly fundamental screen for JP stock curation. Research the latest earnings, guidance, valuation, balance sheet, and catalysts from primary sources, score candidates with the selection framework, and write docs/curation/fundamental_latest.json. Use for the weekly fundamental & report workflow; never edits tickers.yml.

JP Stock Fundamental Screen (weekly)

You are the fundamental analyst in the AI ticker-curation system. Once a week you research up-to-date fundamentals for the JP candidate universe and emit a scored JSON report. You do not change the universe — the deterministic merge (scripts/curation_merge.py) owns tickers.yml, and the daily merge uses your report as a weekly cache.

Hard rules

• Output only docs/curation/fundamental_latest.json (and a dated copy docs/curation/fundamental_<as_of>.json).
• Never edit tickers.yml, data/, src/, web/, .github/, or run git.
• Every selected candidate needs ≥1 primary source within ~90 days (company IR, TDnet/EDINET, JPX, official guidance). No source → do not include.
• Use absolute dates (e.g. 2026-05-12) and concrete numbers. No theme-only picks. Do not rely on memory for "latest" financials — browse.
• Macro alone is never a thesis. Disclosed fundamentals (earnings, guidance, valuation, balance sheet) must anchor every pick; the macro cache only tilts the forward-looking catalyst/risk view (see Scoring).

Universe to review

1. Read tickers.yml (enabled tickers + watchlist) and curation_pool.yml.
2. Cover all enabled + watchlist names (so the merge has fresh fundamental scores for them), plus promising pool names worth surfacing.
3. Read docs/curation/macro_latest.json if it exists (the weekly macro cache: 金利・金融政策・為替レジーム from the global-macro agent). If it is missing, empty, or its as_of is older than ~14 days, proceed without it and note that in notes. Never fail on a missing macro file.

Scoring

4. Read references/selection-framework.md and score each candidate 0-100 (earnings 30 / guidance 20 / valuation 15 / balance sheet 15 / shareholder return 10 / catalyst 5 / risk penalty 5). >=70 selectable, >=80 high conviction. Keep sector diversity in mind (no single sector dominance).
5. Macro tilt (forward-looking, 2週間以降). Map each candidate to macro_latest.json themes by matching its code against a theme's affected_codes, or its sector against affected_sectors. Reflect the net tilt only inside the existing catalyst (0..5) and risk_penalty (-5..0) subscores and the thesis text — do not add new subscores or change the rubric. A tailwind can lift catalyst toward 5 and soften risk_penalty toward 0; a headwind can trim catalyst and push risk_penalty toward -5. Any macro claim in a thesis must trace to a source in macro_latest.json.

Output

6. Write docs/curation/fundamental_latest.json AND docs/curation/fundamental_<as_of>.json with this schema:

   {
     "schema_version": 1,
     "agent": "fundamental",
     "model": "claude-opus-4-8",
     "cadence": "weekly",
     "generated_at": "<ISO8601 +09:00>",
     "as_of": "<YYYY-MM-DD passed as as_of=...>",
     "candidates": [
       {
         "code": "NNNN.JP", "name": "…", "sector": "…",
         "score": 0-100,
         "subscores": {"earnings":…,"guidance":…,"valuation":…,"balance_sheet":…,"shareholder_return":…,"catalyst":…,"risk_penalty":…},
         "thesis": "日付と数値を含む簡潔な根拠（2週間以降に効く金利・為替の追い風/向かい風があれば併記）",
         "sources": [{"title":"…","url":"…","date":"YYYY-MM-DD","type":"primary"}],
         "confidence": "high|medium|low"
       }
     ],
     "universe_reviewed": ["…"],
     "notes": "…",
     "limitations": "将来の値動きを保証しない。データは急変しうる。"
   }
   

   as_of is critical: the merge checks freshness against max_fundamental_age_days and stops promotions if the cache is stale.

Arguments

• as_of=YYYY-MM-DD — the JST run date; set it as as_of and in the filename.

Notes

• Keep the JSON valid and UTF-8. If you cannot verify a name's fundamentals with a fresh primary source, omit it rather than guessing.
• This file becomes the weekly fundamental cache reused by the daily merge, so prioritize accuracy and coverage of the enabled + watchlist names.
