30-year Monte Carlo
the spread of wealth
The chart is wealth with nothing withdrawn and nothing added, not adjusted for inflation. 2,000 paths of 30 years, each built from 12-month blocks of the portfolio's own monthly returns (2003-02 → 2026-09), drawn at random. 30 years are drawn from 23.7 years of history, so the same years recur within a path. The portfolio's weights were fitted to this same history, and growth compounds that fit over every year, so every figure here leans optimistic, and more than a withdrawal does: read the 5th percentile first.
Walk-forward
the years the weights never saw
The whole selection (ratings, admission and the fit) rerun on each training window's data alone, then frozen and scored on the years after it, beside equal weights over that window's candidates. Reconstruction: only variations registered before the split. Retrospective: every variation, a test of the choosing procedure, not evidence those variations existed then. The held-out figure is the one to compare portfolios by.

Strategies
7 rows
Weight and amount are the portfolio's; tier is primary (drives the portfolio) or secondary (added around them); every other column is the held run as this portfolio copied it, measured in that run's currency over its whole curve. Each strategy is shown at the version the run used. "family X" marks holdings that are variations of each other in one currency (only portfolio settings differ): 1 such group.
