The Build a Stock Investment Thesis prompt (Claude, ChatGPT, Gemini, Grok)

Select a watchlist or portfolio ticker to pre-fill placeholders, or copy and replace manually.

You are a senior equity research analyst drafting a research thesis memo for an internal investment committee. Build a structured research thesis memo for [COMPANY_NAME] (ticker: [TICKER]) over a [TIME_HORIZON] research horizon.

## Context
Frame the output as an analytical thesis, not an investment recommendation. Use only facts from SEC filings, earnings calls, and publicly available data. Do not suggest buying, selling, or holding the stock. The memo is intended to organise research, not to direct trades.

## Required Analysis

### Part 1 - One-Line Thesis Statement
A single sentence capturing the core analytical view (e.g. "[COMPANY_NAME]'s [SEGMENT] business is structurally underappreciated by the market because of [REASON], with several measurable catalysts over [TIME_HORIZON]"). Bullish, bearish, or neutral framing is acceptable.

### Part 2 - Variant Perception
- What does the market currently believe about this company? (Cite consensus narrative.)
- Where does the analytical view differ from consensus, and why?
- What specific data or insight supports the differentiated view?

### Part 3 - Three Pillars Supporting the Thesis
For each pillar:
- The claim
- The evidence (specific numbers from filings or disclosures)
- The leading indicator that would confirm it
- The disconfirming signal that would weaken it

### Part 4 - Estimated Fair Value Range
- Base-case estimated fair value with key assumptions
- Bull-case fair value (top-quartile assumptions)
- Bear-case fair value (bottom-quartile assumptions)
- Asymmetry: implied upside / downside vs current market price

(Use neutral terminology - "estimated fair value", not "price target".)

### Part 5 - Catalyst Path
List 3-5 concrete events or data points that could revalue the stock over [TIME_HORIZON]:
| Catalyst | Type (Earnings / Filing / Macro / Event) | Approx. Timing |

### Part 6 - Top 3 Risks to the Thesis
For each risk:
- Description
- Probability (Low / Medium / High)
- Severity if it materialises (Low / Medium / High)
- Early-warning metric to monitor

### Part 7 - Mosaic Score Card
Rate each on 1-5 with 1-line justification:
- Business quality
- Competitive position
- Management quality / capital allocation
- Balance sheet
- Valuation (relative & absolute)
- Catalyst clarity
- Conviction level (acknowledging unknowns)

### Part 8 - Research Agenda Before Sizing Up
List 5 follow-up questions or data points to verify before increasing conviction.

### Part 9 - Visual Verification & Chart Follow-Up
- Identify 2-3 visual inflection points that require multi-year chart inspection (e.g. 10-year FCF conversion, operating leverage inflection points, and long-term valuation percentiles).
- Provide the direct Chartloom visual research link for the user to inspect these 10-year interactive charts: https://www.chartloom.com/c/ticker/[TICKER]

## Output Format
Tables, headers, bullets. Neutral, evidence-driven language. Do not provide investment advice. Avoid the words "buy", "sell", "hold", "recommendation", or "price target".

**Variables:** If any [BRACKETED] placeholders above are not set, ask the user for each missing value before proceeding.

Variables

Replace these placeholders in the prompt with your own values.

PlaceholderDescriptionExample
[COMPANY_NAME]Company name.Uber Technologies
[TICKER]Stock ticker symbol.UBER
[TIME_HORIZON]Research horizon for the thesis (e.g. 12 months, 2-3 years, 5+ years).2-3 years

How to use this prompt

Replace [COMPANY_NAME], [TICKER], and [TIME_HORIZON]. For higher quality, paste the latest 10-K MD&A and most recent earnings transcript alongside the prompt so the AI can ground each pillar in primary evidence. Treat the output as a research artefact - it is not investment advice.

Tips

  • The variant perception is the single most important section - if your view matches consensus, the thesis has no edge.
  • Each pillar must come with a leading and a disconfirming indicator - this is what separates a thesis from a marketing pitch.
  • Use the catalyst calendar prompt to populate Part 5 with verifiable events.
  • The bear-case fair value is often the most diagnostic number - if it is far below the current market price, the asymmetry may be unfavourable.
  • Re-read the memo 90 days later and check whether the leading indicators are tracking - this is how disciplined researchers update conviction.

When to use this prompt

Drafting a research memo before initiating coverage on a new name

Upgrading an existing watch-list note into a structured thesis after a catalyst

Stress-testing a high-conviction view against a written variant perception

Preparing for an internal investment committee or peer review session
