An AI fund manager
The portfolio is run by an autonomous AI agent. It reads filings, prices and news, forms a thesis, and places its own trades. No human overrides its calls.
A live experiment · Kingston, Jamaica
Can an AI beat the Jamaica Stock Exchange?
I handed an autonomous AI a portfolio and one mandate: grow it — using nothing but JSE-listed stocks. It researches, decides, and trades on its own. Every move is published here, wins and losses.

The Experiment
One AI. One portfolio.
The whole market watching.
Most people never see how a portfolio is actually run. I'm putting one on the record — managed end-to-end by AI, scored against the market, with nowhere to hide.
JSE stocks only
No US tech, no crypto, no shortcuts. The entire universe is the Jamaica Stock Exchange — Main and Junior markets — so the results say something real about investing at home.
Radical transparency
Positions, trades, reasoning and returns are published as they happen. If the AI underperforms the market, you'll see that too — that's the point.
How It Works
Research. Trade. Report. Repeat.
-
01
The AI does its homework
Each trading day it ingests JSE closing prices, company results and market news, then re-scores every listing against its strategy.
-
02
It makes the call
Buy, sell, hold, or sit in cash — the AI decides position sizes and timing on its own, inside strict risk rules it can't break.
-
03
Everything goes public
Every decision lands on the scoreboard with the reasoning behind it, and performance is measured against the broad JSE market.
-
04
You keep score with me
Subscribers get performance recaps and JSE market updates — so you can judge for yourself whether the machine can really invest.

FAQ
Fair questions
Is this investment advice?
No. YaadInvest is a public experiment and a learning project. Nothing here is a recommendation to buy or sell any security. Always do your own research or speak to a licensed advisor.
What exactly does the AI do?
It runs the full investment loop: gathering JSE market data, analysing companies, deciding what to buy or sell and in what size, and logging its reasoning. I maintain the system and its risk limits, but I don't make trading decisions.
Which stocks can it pick?
Anything listed on the Jamaica Stock Exchange — Main Market or Junior Market — and nothing else. Cash is the only other position it can hold.
How is performance measured?
Against the broad JSE market, using YaadInvest's transparent composite indices (chained median daily return, base 1000) built from official closing prices. You can inspect the market side any time on the market dashboard.
How often will you post updates?
The scoreboard updates after each trading session. Subscribers get periodic recaps of performance plus notable JSE market moves.
What happens if the AI loses money?
It stays on the record. The experiment is only interesting if the results are honest — drawdowns, bad calls and all.
