The portfolio's annual return
The time-weighted return expressed as a yearly rate.
In the demo portfolio
+10.8%
How it is computed here
The total growth compounded down to a year, geometrically. A period shorter than a week is not annualised at all, because multiplying a few days up to a year produces absurd figures.
Worked example
- +84.3% over 5.98 calendar years, from 2019-01-07 to 2024-12-31.
- (1 + 0.843) ^ (1 ÷ 5.98) − 1 = +10.8% a year.
Demo portfolio: four invented companies, generated prices, measured by the real engine. Past returns do not predict future ones.
Where it misleads
Annualising a short window is the most common way to make a lucky month look like a career.
