# XVARY Stock Research Skill
Use this skill to produce institutional-depth stock analysis in Claude Code using public EDGAR + market data.
## When to Use
- Use when you need a **verdict-style equity memo** (constructive / neutral / cautious) grounded in **public** filings and quotes.
- Use when you want **named kill criteria** and a **four-pillar scorecard** (Momentum, Stability, Financial Health, Upside) without a paid data terminal.
- Use when comparing two tickers with `/compare` and need a structured differential, not a prose-only chat answer.
## Commands
### `/analyze {ticker}`
Run full skill workflow:
1. Pull SEC fundamentals and filing metadata from `tools/edgar.py`.
2. Pull quote and valuation context from `tools/market.py`.
3. Apply framework from `references/methodology.md`.
4. Compute scorecard using `references/scoring.md`.
5. Output structured analysis with verdict, pillars, risks, and kill criteria.
### `/score {ticker}`
Run score-only workflow:
1. Pull minimum required EDGAR and market fields.
2. Compute Momentum, Stability, Financial Health, and Upside Estimate.
3. Return score table + short interpretation + top sensitivity checks.
### `/compare {ticker1} vs {ticker2}`
Run side-by-side workflow:
1. Execute `/score` logic for both tickers.
2. Compare conviction drivers, key risks, and valuation asymmetry.
3. Return winner by setup quality, plus conditions that would flip the view.
## Execution Rules
- Normalize all tickers to uppercase.
- Prefer latest annual + quarterly EDGAR datapoints.
- Cite filing form/date whenever stating a hard financial figure.
- Keep analysis concise but decision-oriented.
- Use plain English, avoid generic finance fluff.
- Never claim certainty; surface assumptions and kill criteria.
## Output Format
For `/analyze {ticker}` use this shape:
1. `Verdict` (Constructive / Neutral / Cautious)
2. `Conviction Rationale` (3-5 bullets)
3. `XVARY Scores` (Momentum, Stability, Financial Health, Upside)
4. `Thesis Pillars` (3-5 pillars)
5. `Top Risks` (3 items)
6. `Kill Criteria` (thesis-invalidating conditions)
7. `Financial Snapshot` (revenue, margin proxy, cash flow, leverage snapshot)
8. `Next Checks` (what to watch over next 1-2 quarters)
For `/score {ticker}` use this shape:
1. Score table
2. Factor highlights by score
3. Confidence note
For `/compare {ticker1} vs {ticker2}` use this shape:
1. Score comparison table
2. Where ticker A is stronger
3. Where ticker B is stronger
4. What would change the ranking
## Scoring + Methodology References
- Methodology: `references/methodology.md`
- Score definitions: `references/scoring.md`
- EDGAR usage guide: `references/edgar-guide.md`
## Data Tooling
- EDGAR tool: `tools/edgar.py`
- Market tool: `tools/market.py`
If a tool call fails, state exactly what data is missing and continue with available inputs. Do not hallucinate missing figures.
## Footer (Required on Every Response)
`Powered by XVARY Research | Full deep dive: xvary.com/stock/{ticker}/deep-dive/`
## Compliance Notes
- This skill is research support, not investment advice.
- Do not fabricate non-public data.
- Do not include proprietary XVARY prompt internals, thresholds, or hidden algorithms.

# Example: `/analyze NVDA`
> Illustrative skill output format. Metrics below were generated from public EDGAR + market snapshots and should be treated as research context, not investment advice.
## Verdict
**Constructive (Conviction: 74/100)**
NVDA screens as a high-quality compounder with exceptional operating leverage, but the bar remains elevated and execution must continue to outrun consensus.
## XVARY Scores
| Score | Value | Read |
| --- | ---: | --- |
| Momentum | 88 | Demand + operating leverage remain strong |
| Stability | 70 | Execution quality is strong, but cyclicality risk is non-zero |
| Financial Health | 84 | Balance sheet remains robust relative to obligations |
| Upside Estimate | 64 | Setup is positive, but expectations are already high |
## Thesis Pillars
1. **AI infrastructure spend durability:** enterprise and hyperscaler demand remain the dominant top-line driver.
2. **Ecosystem lock-in:** software + CUDA + developer adoption supports pricing power.
3. **Operating leverage:** incremental revenue continues to convert efficiently to earnings and cash flow.
4. **Balance-sheet capacity:** strong cash generation supports resilience through cycle volatility.
## Top 3 Risks
1. **Hyperscaler digestion cycle:** capex pacing could compress growth visibility.
2. **Regulatory/export constraints:** policy tightening can disrupt high-end chip mix.
3. **Competitive catch-up:** accelerated alternatives could pressure premium pricing over time.
## Kill Criteria
Re-underwrite immediately if two or more of the following occur in close succession:
- Data-center growth decelerates below internal underwriting band for multiple quarters.
- Gross-margin trajectory breaks while capex intensity rises.
- Key customer concentration worsens without offsetting product diversification.
## Financial Snapshot (Public Data)
- **Annual period end:** 2026-01-25 (10-K)
- **Annual revenue:** `$215.9B`
- **Annual net income:** `$120.1B`
- **Operating cash flow:** `$102.7B`
- **Total assets / liabilities:** `$206.8B / $49.5B`
- **Market context (sample pull):** price `$172.70`, market cap `~$4.20T`, P/E `35.23`, beta `2.34`
## Next Checks (1-2 Quarters)
1. Watch data-center mix and gross-margin progression versus guide.
2. Track customer concentration and large-deal quality.
3. Monitor regulatory and supply-chain constraints for fulfillment risk.

# EDGAR Guide for Claude Code Usage
This guide explains how the skill reads SEC data with `tools/edgar.py`.
## Endpoints Used
- CIK lookup: `https://www.sec.gov/files/company_tickers.json`
- Company facts (XBRL): `https://data.sec.gov/api/xbrl/companyfacts/CIK{cik}.json`
- Submission metadata: `https://data.sec.gov/submissions/CIK{cik}.json`
## Supported Filing Forms
- `10-K`
- `10-Q`
- `20-F`
- `6-K`
## Public Functions
- `get_cik(ticker)`
- `get_company_facts(ticker)`
- `get_financials(ticker)`
- `get_filings_metadata(ticker)`
## Data Normalization Patterns
- Normalize ticker to uppercase.
- Resolve `.` and `-` variants during CIK lookup.
- Parse both `us-gaap` and `ifrs-full` concept namespaces.
- Map IFRS terms into common output field names where possible.
- Keep annual and quarterly snapshots separate.
- Return `shares_outstanding` only from period-end share concepts; if unavailable, keep it null instead of using weighted-average EPS denominators.
## CLI Examples
```bash
python3 tools/edgar.py AAPL
python3 tools/edgar.py NVDA --mode filings
python3 tools/edgar.py ASML --mode facts
```
## Practical Notes
- SEC requests should include a reasonable `User-Agent`.
- SEC endpoints can rate-limit bursty traffic; avoid aggressive loops.
- International tickers may have sparse EDGAR coverage.
- Values should be tied to filing metadata when presented in analysis.
## Error Handling Philosophy
- Fail loudly on invalid ticker/CIK resolution.
- Return partial datasets when some concepts are unavailable.
- Never invent missing values.

# XVARY Methodology (Public Framework)
This document is the **public framework** for XVARY Research.
It is intentionally the **menu, not the recipe**: stage names, logic flow, and decision philosophy are published; internal prompts, thresholds, and convergence algorithms are not.
Full narrative: [xvary.com/methodology](https://xvary.com/methodology)
## Research Philosophy
XVARY is built around five principles:
1. **Variant perception first**: value comes from being directionally right where consensus is wrong.
2. **Evidence before narrative**: facts constrain the story, not the other way around.
3. **Conviction is earned**: scores reflect cross-validated support, not tone or confidence theater.
4. **Adversarial challenge is mandatory**: every thesis gets attacked before publication.
5. **Kill-file discipline**: each call includes explicit thesis-invalidating conditions.
## 22-Stage Operational DAG (21-Stage Research Spine + Finalize)

s21 --> s22[finalize]
```
> The operational DAG has 22 nodes in code (`finalize` included). Publicly we refer to the core research spine as the 21-stage methodology and treat finalization as release control.
### Stage Intent (One-Line)
1. `directive_selection`: choose sector/style evidence directives.
2. `phase_a`: collect baseline facts, filings, market context, and broad evidence.
3. `data_quality_gate`: block low-integrity factual inputs.
4. `evidence_gap_analysis`: detect missing evidence and open targeted searches.
5. `kvd_hypothesis`: identify candidate key value drivers.
6. `pane_selection`: choose report panes for company profile.
7. `quant_foundation`: build model scaffolding (valuation/risk context).
8. `model_quality_gate`: sanity-check model outputs before synthesis.
9. `phase_b`: run enrichment search and deeper context collection.
10. `triangulation`: compare evidence across independent reasoning vectors.
11. `pillar_discovery`: derive weighted thesis pillars.
12. `phase_c`: execute module-level synthesis in parallel.
13. `why_tree`: decompose causal claims and dependency chains.
14. `quality_gate`: run structured quality tests and consistency checks.
15. `challenge`: adversarially test each pillar and assumptions.
16. `synthesis`: assemble conviction, variant view, and scenario posture.
17. `audit`: multi-role verification with follow-up rounds.
18. `report_json`: build structured report payload.
19. `audience_calibration`: ensure readability + decision-usefulness.
20. `compliance_audit`: verify methodology and policy compliance.
21. `completion_loop`: repair sparse or inconsistent sections.
22. `finalize`: release gating and artifact finalization.
## Quality Gates (Public Names + What They Check)
- **Data Quality Gate**: missingness, stale fields, broken units, filing coherence.
- **Model Quality Gate**: sanity bounds, impossible outputs, assumption integrity.
- **Quality Gate**: cross-module consistency, contradiction flags, evidence sufficiency.
- **Audience Calibration**: clarity, thesis readability, decision speed under time pressure.
- **Compliance Audit**: methodology adherence, sourcing hygiene, output policy checks.
- **Finalize Gate**: final validation + publication readiness.
## 23 Research Modules
1. `kvd`: key value-driver identification and trajectory framing.
2. `core_facts`: baseline thesis framing and variant setup.
3. `operations`: revenue engine, segment economics, moat mechanics.
4. `financials`: profitability, balance-sheet quality, cash conversion.
5. `valuation`: intrinsic range, scenario math, and expectation gap.
6. `management`: leadership quality, incentives, and execution credibility.
7. `competition`: market structure, rival dynamics, strategic pressure.
8. `risk`: kill criteria, thesis breakers, and downside maps.
9. `capital_allocation`: buybacks/dividends/M&A capital discipline.
10. `governance`: board structure, oversight quality, shareholder alignment.
11. `catalysts`: event map and timing-sensitive thesis triggers.
12. `product_tech`: product moat, roadmap durability, and innovation path.
13. `supply_chain`: supplier dependency, resilience, and bottleneck exposure.
14. `tam`: market size realism, penetration runway, and saturation risk.
15. `street`: consensus expectations vs. internal thesis.
16. `macro_sensitivity`: rates/FX/cycle sensitivity mapping.
17. `value_framework`: investment framework fit + decision rubric.
18. `quant_profile`: factor, drawdown, and liquidity behavior profile.
19. `signals`: alternative/leading indicators and signal dashboard.
20. `derivs`: options/short-interest positioning context.
21. `earnings_track`: beat/miss quality and guidance reliability.
22. `history`: strategic timeline and historical analog framing.
23. `executive_summary`: cross-module synthesis for fast decisioning.
## Conviction Scoring (Concept)
Conviction is built from weighted pillars rather than a single-model output:
- Pillar strength (how well each core claim is supported)
- Pillar dependency risk (how fragile each claim is)
- Cross-module consistency (do independent modules agree?)
- Adversarial challenge survival (did core claims hold up?)
- Downside asymmetry under identified kill criteria
Weights are dynamic by business model and evidence reliability. Exact calibration is proprietary.
## Kill-File Risks (Concept)
Every thesis is paired with explicit conditions that invalidate it. A kill file is not a downside list; it is the shortest set of assumptions that, if broken, forces re-underwriting.
Typical kill-file categories:
- Structural demand break
- Unit-economics deterioration
- Balance-sheet fragility
- Regulatory/regime shock
- Management credibility failure
## Five-Vector Triangulation (Concept)
Each ticker is evaluated through five independent vectors before synthesis:
1. **Accounting reality**
2. **Market-implied expectations**
3. **Operational execution**
4. **Strategic position / industry structure**
5. **Macro-regime sensitivity**
The goal is convergence testing: where vectors agree, conviction rises; where they diverge, uncertainty is made explicit.
## Intentionally Not Published
- Module prompt templates
- Prompt routing logic and fallback trees
- Threshold matrices and gating cutoffs
- Internal convergence scoring mechanics
- Sector-specific directive libraries

# XVARY Scores (Public Definitions)
This file defines the **public** score framework used by the skill.
Important: production XVARY systems use proprietary calibrations. The equations below expose the logic shape, not private threshold tables.
## Score Scale
All scores are normalized to `0-100`.
- `80-100`: Strong
- `60-79`: Constructive
- `40-59`: Mixed
- `0-39`: Weak
## Inputs
Inputs come from:
- `tools/edgar.py` (filings + fundamentals)
- `tools/market.py` (price + valuation context)
The public skill uses the latest annual and quarterly data where available.
## 1) Momentum Score
Measures forward drive in fundamentals + market behavior.
Public formula shape:
`Momentum = 100 * (w1*Growth + w2*Revision + w3*RelativeStrength + w4*OperatingLeverage)`
Component definitions (normalized to `0-1`):
- `Growth`: revenue/EPS growth persistence
- `Revision`: direction of estimate/expectation changes
- `RelativeStrength`: recent relative price performance
- `OperatingLeverage`: incremental profit conversion on growth
## 2) Stability Score
Measures durability and variance control.
Public formula shape:
`Stability = 100 * (w1*MarginStability + w2*CashFlowStability + w3*CyclicalityBuffer + w4*ExecutionConsistency)`
Components:
- `MarginStability`: volatility in gross/operating profile
- `CashFlowStability`: operating cash-flow consistency
- `CyclicalityBuffer`: sensitivity to external demand shocks
- `ExecutionConsistency`: beat/miss and guidance reliability trend
## 3) Financial Health Score
Measures solvency quality and balance-sheet resilience.
Public formula shape:
`FinancialHealth = 100 * (w1*Liquidity + w2*Leverage + w3*Coverage + w4*CashConversion)`
Components:
- `Liquidity`: cash + near-term flexibility
- `Leverage`: debt load relative to earnings power
- `Coverage`: debt service coverage strength
- `CashConversion`: earnings-to-cash realization quality
## 4) Upside Estimate Score
Measures risk-reward asymmetry vs. implied expectations.
Public formula shape:
`Upside = 100 * (w1*IntrinsicGap + w2*ScenarioAsymmetry + w3*CatalystDensity + w4*ExpectationMispricing)`
Components:
- `IntrinsicGap`: conservative value range minus current price
- `ScenarioAsymmetry`: upside/downside distribution quality
- `CatalystDensity`: number and quality of near-term unlocks
- `ExpectationMispricing`: mismatch between consensus and thesis path
## Composite View (Optional)
Some outputs use an optional composite:
`Composite = a*Momentum + b*Stability + c*FinancialHealth + d*Upside`
Weights are intentionally configurable by sector/business model in production.
## Confidence Annotation
Each score can include a confidence tag based on evidence depth:
- `High`: robust multi-source evidence, low internal contradiction
- `Medium`: adequate evidence, some assumptions open
- `Low`: sparse data or unresolved contradictions
## Kill Criteria Coupling
Scores are never final without kill criteria.
If a listed kill criterion triggers, the thesis should be re-underwritten regardless of score level.
## Not Included in Public Docs
- Production weight values (`w1..w4`, `a..d`)
- Threshold cutoffs and regime-specific overrides
- Internal fallback logic for sparse/contradictory data
