How to read it

Four numbers. Nothing else.

Using the Apple example above.

1 · CHANCE IT GOES UP48%

Out of 10,000 simulated futures, 48 in every 100 end above today’s price after 30 days.

2 · CHANCE IT GOES DOWN52%

The other 52 end below. Here it is close to a coin flip: no strong signal either way.

3 · LIKELY RANGE$290 – $366

9 times out of 10 the price ends somewhere in this range. The wider it is, the riskier the stock.

4 · BAD CASE−11.3%

Only 1 future in 20 ends worse than this. It tells you how much you could lose in a bad month.

How it works

Three steps, done for you.

  1. 01

    Choose

    A US stock or ETF, and a time frame from 1 day up to 1 year.

  2. 02

    Simulate

    ATLAS plays out 10,000 possible paths for the price, using how much that stock really moves. It recalibrates every night after the market closes.

  3. 03

    Count

    It counts how many paths end up, how many end down, and where most of them land. That is the answer.

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.
