Asset and role
What is the position, and what job should it do in your portfolio?
Example: Long-term growth position, income holding, cash reserve, inflation hedge, or higher-risk satellite.
Investment thesis template
A simple template for writing why you own it.
Use this structure to make a position reviewable: why you own it, what must stay true, what would change your mind, and how it fits the rest of your portfolio.
Quick thesis
Position
ASML Holding
Why I own it
Monopoly-like position in EUV lithography, with long-term demand tied to advanced chips.
Review trigger
Thesis needs review if order backlog weakens for multiple quarters.
The template
Six prompts that make a thesis easier to review.
You do not need a long essay. A clear thesis is often a few honest paragraphs and a specific review trigger.
Why I own it
Write the plain-language reason you bought or kept the asset.
Example: I own this because I believe the company can keep expanding margins while revenue grows.
Core thesis
Summarize the main belief that must remain true for the position to make sense.
Example: The business can compound earnings faster than the market expects over the next five years.
What would change my mind
Define the evidence that would make you reduce, sell, or review the position.
Example: Revenue growth stalls for several quarters, debt rises sharply, or the competitive advantage weakens.
Time horizon
How long are you willing to let the thesis play out, and when should you review it?
Example: Review after the next two earnings reports, or once the position reaches a target allocation.
Key risks
Name the biggest risks instead of hiding them in the back of your mind.
Example: Valuation risk, concentration risk, regulation, currency exposure, or execution risk.
Thesis checklist
The template should move from blank to reviewable.
A thesis is useful when it creates a future review path. These are the checkpoints Horyzon is designed to keep close to each position.

How Horyzon helps
Keep the template beside the holding.
Horyzon turns this template into a habit. You can track the asset, write the thesis, and revisit the reason later when price movement starts to distort memory.
One thesis per position
Write the reasoning directly beside the stock, ETF, crypto asset, commodity, or cash holding.
Review triggers
Make it clear what evidence would change your mind before emotions take over.
Portfolio context
See whether a position is a core holding, hedge, cash reserve, or higher-risk satellite.
AI with context
Horyzon Pro can answer questions using your holdings and the thesis you wrote.
In the app

What should an investment thesis include?
A useful investment thesis usually includes why you own the asset, what must stay true, what would change your mind, the role of the position, key risks, and a review date.
Can I use this template for ETFs or crypto?
Yes. The same structure can work for stocks, ETFs, crypto assets, commodities, and cash, as long as the thesis explains the role of the asset and the risks you are accepting.
Does Horyzon tell me what my thesis should be?
No. Horyzon helps you record and review your own reasoning. It is for portfolio tracking and informational analysis only, not financial advice.
