The Thesis Template

A fill-in template you can use today, a worked example, how the thesis feeds a simple DCF — and how its kill criteria become rules Telumin watches around the clock.

The template

Nine sections, one page. If you can’t fill in sections 2 and 6 — variant perception and kill criteria — you don’t have a thesis yet; you have a feeling.

thesis-template.txt
Investment Thesis — [Company] ([TICKER])
Date: [YYYY-MM-DD] · Version: 1.0

1. One-sentence thesis
   [Clear, falsifiable: why you own it and what drives the return]

2. Variant perception
   [Why is the market wrong or incomplete right now?]

3. Business quality & moat
   [Model · advantages · unit economics · management]

4. Valuation
   [Method used (DCF, multiples) · intrinsic value · margin of
    safety · what the market is already pricing in]

5. Catalysts
   [Specific events that close the price/value gap, with timing]

6. Risks → kill criteria (break-conditions)
   [Risk 1 → measurable break condition]
   [Risk 2 → measurable break condition]
   [Risk 3 → measurable break condition]

7. Expected return & horizon
   [Base-case annualized return · horizon · up/base/down cases]

8. Position sizing & role
   [Weight and what job it does in the portfolio]

9. Monitoring plan
   [What you track, how often you formally review]

A worked example (abridged)

Illustration, not analysis

The example below is educational — illustrative numbers and reasoning to show the form, not a recommendation or a current view on any security.

Investment Thesis — Costco (COST)          [illustrative example]

1. One-sentence thesis
   A high-quality compounder whose membership model can grow free
   cash flow mid-to-high single digits for many years — still
   underappreciated at today's price.

2. Variant perception
   The market treats it as a fully-priced, low-growth retailer and
   underweights the membership flywheel, fee pricing power, and the
   warehouse-expansion runway.

6. Risks → kill criteria
   Renewal rates begin a sustained decline      → review immediately
   Operating margins compress structurally      → reassess thesis
   Large value-destructive acquisition          → exit
   Comparable sales slow with no temporary cause→ formal review

9. Monitoring plan
   Membership metrics, comps, margins, fee moves — every quarter.
   Full review yearly, or the moment any kill criterion fires.

Notice the shape of section 6: every risk ends in a measurable condition and a predefined action. That is what makes a thesis monitorable — by you, or by a machine.

Linking the thesis to a simple DCF

The thesis is the story; the DCF turns the story into numbers. Each qualitative judgment maps to a specific assumption:

Thesis section          →  DCF assumption it feeds
─────────────────────────────────────────────────────────────
Variant perception +    →  growth rate, margin stability,
business quality           and a defensible discount rate
Catalysts               →  higher near-term growth years
Risks & kill criteria   →  the downside / sensitivity cases
Valuation               →  where the DCF's output lands
Expected return         →  (DCF value ÷ price) − 1, annualized
1.

Write the qualitative thesis first

Judgments before numbers — otherwise the model launders your bias into precision.

2.

Translate judgments into assumptions

Durable moat → steadier growth and a lower discount rate you can defend. Catalysts → the years that carry above-trend growth. Keep the terminal rate boring.

3.

Run the base case — then run the kill cases

Re-run the same model with each break-condition triggered: lower growth, compressed margins, a higher discount rate. If even the kill cases are survivable, the thesis is robust; if not, you have learned your true margin of safety.

4.

Write the output back into the thesis

The DCF’s value fills section 4; the spread to today’s price fills section 7. When a kill criterion later fires, the first thing you do is re-run the model with the new reality — the second is decide.

Wiring it into Telumin

Telumin is built for exactly one stage of this process: the monitoring. When you add a position, you write the reason in one line — the engine structures it into break-conditions and watches them continuously. Section 6 of your thesis is not a document you revisit yearly; it is a set of live rules.

  • · Kill criteria → the thesis drift sweep re-checks them against filings, prices, and news.
  • · Price-level risks → stop-loss watchers hold the line 24/7; the order stays yours.
  • · The decision log → every accept/reject lands in the journal with your reason, building the review trail section 9 asks for.
  • · Connected to Claude via MCP, you can draft the thesis in conversation and save the finished analysis — verdict, scored dimensions, evidence — back to Telumin, shareable by link.
