Portfolio builder
Tell it your goal. It builds the portfolio.
Say how much you have, what return you want and by when. ATLAS checks every US stock and ETF and returns the mix with the best odds of getting there: what to buy, how much of each, and the chance it works.

How it works
From a goal to a list of buys.
- 01
Your goal
Budget, target return and time frame. Nothing else to fill in.
- 02
The search
ATLAS looks at 5,000+ US stocks and 2,400+ ETFs and tries thousands of combinations, simulating each one many times.
- 03
The best odds
It keeps the mix most likely to reach your target, spread so that one bad stock cannot sink it.
- 04
The answer
A short list: each stock or ETF, its weight, the shares to buy with your budget, and the odds of hitting the goal or losing money.
A real one
A portfolio built by ATLAS, followed in public.
We gave the engine $10,000 of virtual capital in April and let it build and manage the portfolio. Here is how it has done against the S&P 500.
Figures on 13 September 2026. Virtual capital: real prices and real rules, no client money. Past results do not promise future results.
Does it work?
We check every forecast.
Since 1 October 2026 every forecast is saved before the market opens and later compared with the real price. Earlier months were rebuilt day by day using only the data available the evening before. When ATLAS says “8 in 10”, it should happen about 8 in 10 times.
