Stock Due Diligence Framework

Que fait ce prompt ?

Les investisseurs individuels, gérants de portefeuille et analystes utilisent ce prompt pour mener une due diligence rigoureuse et structurée sur une action avant d'initier ou de renforcer une position. Il remplace des heures de lecture non structurée par un cadre systématique couvrant toutes les dimensions qu'un analyste actions professionnel examinerait.

Prompts

You are a senior equity analyst conducting full due diligence on [STOCK TICKER] for a [INVESTOR TYPE] with a [TIME HORIZON] investment horizon. Use publicly available information and the financial data I provide below to produce a structured due diligence report.

Financial Data Provided:
[FINANCIAL DATA — revenue, margins, FCF, balance sheet, valuation multiples]

Produce a structured due diligence report covering the following sections:

1. **Business Model Assessment**
   Describe how the company generates revenue, its primary customer segments, and its unit economics. Identify whether the business is capital-light or capital-intensive. Assess the quality and predictability of earnings.

2. **Competitive Moat Analysis**
   Evaluate the strength and durability of the company's competitive advantage using the following moat categories: cost advantage, switching costs, network effects, intangible assets (brands, patents), and efficient scale. Rate each moat type as Strong, Moderate, Weak, or Absent with a one-sentence rationale.

3. **Financial Health Review**
   Analyze the following metrics and flag any concerns:
   - Revenue growth: trailing three-year CAGR and trend direction
   - Gross and operating margins: levels and trajectory
   - Free cash flow conversion: FCF as a percentage of net income
   - Balance sheet strength: net debt position, interest coverage, current ratio
   - Return metrics: ROIC and ROE versus cost of capital

4. **Valuation Assessment**
   Present current valuation multiples (P/E, EV/EBITDA, P/FCF, P/S) versus the five-year historical average and closest peers. State whether the stock appears overvalued, fairly valued, or undervalued, and identify the primary valuation driver.

5. **Risk Register**
   List the top five risks in priority order: macro risks, industry-specific risks, company-specific risks, and regulatory or ESG risks. For each risk, assess probability (Low/Medium/High) and potential impact (Low/Medium/High).

6. **Investment Verdict**
   Provide a clear investment recommendation: Buy, Hold, or Avoid. State the primary thesis in two sentences, the key bull-case assumption that must hold, and the single biggest risk that would invalidate the thesis.

Write with the precision of a professional research note. Flag any data gaps explicitly rather than speculating.

Ce que vous obtiendrez

Un rapport de due diligence en six sections couvrant le modèle économique, le fossé concurrentiel avec évaluation par catégorie, les indicateurs de santé financière avec signaux de tendance, l'évaluation de la valorisation versus pairs et historique, un registre des risques avec probabilité et impact, et un verdict clair Acheter/Conserver/Éviter.

💡 Conseil d'Expert

Exécutez ce prompt avant et après une publication de résultats pour voir comment la thèse d'investissement évolue. Les sections sur le fossé concurrentiel et la santé financière sont particulièrement sensibles aux mises à jour trimestrielles — même de petits glissements de marge peuvent changer le verdict.

Best for long-form, nuanced due diligence reports. Paste financial data as structured text or tables. Claude maintains consistency across all six sections and produces publication-quality prose. Use follow-up prompts to stress-test specific assumptions.

Strong for structured output. GPT-4o with browsing can pull recent filing data and news for public companies. Combine with data from SEC EDGAR or the company's investor relations page for best results.

Excellent for real-time data enrichment. Use Perplexity to source current valuation multiples, recent analyst ratings, and news before feeding context into Claude or ChatGPT for the full framework.
