Time-weighted return
What the portfolio itself earned, with the effect of your deposits removed.

How it is computed here
Each day's return is computed after subtracting that day's contribution, and the daily returns are chained. It is the same convention funds must publish, which is what makes it comparable to an index.
Worked example
- The daily return of the holdings is chained over every session: (1 + r₁) × (1 + r₂) × … − 1.
- Deposits and withdrawals are taken out of each day before chaining, so adding money never looks like a gain.
- Over the whole history the chain gives +84.3%.
Demo portfolio: four invented companies, generated prices, measured by the real engine. Past returns do not predict future ones.
Where it misleads
It deliberately ignores how much money you had in at each moment. It is the right measure of the holdings and the wrong one for your wallet — the money-weighted figure is the other half.
