What Bonsai Compass gives you back

Bonsai CompassChallenging thesis

Your thesis

“I want to buy a semiconductor ETF because AI infrastructure spending will keep growing.”

Bull Case

AI infrastructure spending could keep expanding as enterprises and cloud providers invest in compute capacity.

Bear Case

Expectations may already be priced in. Demand could normalize or hyperscaler spending could slow.

Hidden Assumptions

You assume AI workloads grow faster than efficiency gains and chip leaders keep pricing power.

Missing Evidence

ETF concentration, forward multiples, customer capex guidance, export-control exposure.

Thesis Breakers

Cloud providers cut AI capex, model efficiency reduces compute intensity, or export restrictions widen.

Conviction Score

Not a buy rating. Strong case, unresolved assumptions.

74/100

A simpler pre-investment workflow.

Built for the moment when you have an idea, but not enough conviction yet.

What you get after the challenge.

  • Conviction score

    Measures thesis completeness, evidence quality, downside clarity, and falsifiability. It is not a buy or sell rating.

  • Follow-up chat

    Probe the gaps in the challenge without getting a trade call, price target, or allocation advice.

  • Saved thesis journal

    Keep the idea, the challenge, and your notes in one place so you can come back before you act.

  • No picks, alerts, or trade calls

    Bonsai Compass challenges an idea you bring. It does not tell you what to buy.

For investors who already have an idea.

The question is not what to buy. It is whether your thesis deserves more conviction, more research, or more skepticism.

Is Bonsai Compass financial advice?

No. Bonsai Compass is a research workflow tool. It does not recommend trades, assets, allocations, or portfolio changes.

Does Bonsai Compass pick stocks?

No. It starts with an idea you already have and tests the logic, assumptions, risks, and missing evidence behind it.

What assets does it support?

Bonsai Compass is designed for stocks, ETFs, macro, and crypto investment ideas.

What does the conviction score mean?

It measures how complete and falsifiable the thesis is: evidence quality, downside clarity, and remaining gaps. It is not a recommendation to buy or sell.
