How it is calculated

Portfolio return = sum(asset weight × asset return) ÷ sum(weights). Dividing by the sum of weights normalizes the result in case the entered weights don't add up to exactly 100% — so the return comes out correct regardless of small rounding.

Weighted return isn't a simple average of the assets' returns — it's a weighted average: an asset with a larger portfolio weight has more influence on the overall result, even if its own return is lower than that of smaller positions.

The calculation gives the return over the same period for all assets at once — it doesn't account for asset weights shifting during the period as their values move differently; for evaluating several periods in a row, weights need to be recomputed at the start of each period.
