Investment Thesis Template: From Narrative to Testable Decision
A structured thesis template that turns stock ideas into falsifiable assumptions, downside maps, and review triggers.
Most weak investments fail before the first trade because the thesis is vague. This template forces clarity on what must be true, what could break, and how evidence should be tracked over time.

Step 2
Counter-thesis and downside path
Write the strongest bear case before entry. This improves risk awareness and reduces confirmation bias after the position is open.
Step 3
Review schedule and invalidation triggers
Define when to re-underwrite and what evidence invalidates the thesis. This prevents narrative drift during volatility.
Framework
1) One-page thesis with falsifiable claims
State the business edge, expected return drivers, and key assumptions in plain language. If assumptions are not testable, the thesis is too weak to size confidently.
2) Counter-thesis and downside path
Write the strongest bear case before entry. This improves risk awareness and reduces confirmation bias after the position is open.
3) Review schedule and invalidation triggers
Define when to re-underwrite and what evidence invalidates the thesis. This prevents narrative drift during volatility.

FAQ
How long should a thesis document be?
For most positions, one focused page is enough if assumptions, valuation logic, and invalidation triggers are explicit.
Should I rewrite the thesis after every earnings report?
Update only when key assumptions materially change. Keep a version history so you can track whether process quality is improving.
Can this template be used for ETFs?
Yes. Replace company-level assumptions with exposure, factor, and macro assumptions relevant to the ETF strategy.
