What happens after you invest?

You buy the target pie, then prices move. By the next rebalance your weights are no longer the ones you chose — winners grow, losers shrink, and cash holds still. Below is one rebalance period of real price history applied to today's weights. Rebalancing sells a little of what grew and tops up what shrank, to put the pie back on target.

Period ending 2026-06-30. Changes are in percentage points of weight — not gains or losses.

Between 2021-08-31 and 2022-12-31 — the pie's worst stretch — its realised beta was 0.57, against a headline 0.75. A beta estimated over calm months is not a promise about how it behaves in a fall.

Read this before you believe any number above.
  • 23-month simulated track — too short to be statistically significant
  • survivorship-biased universe
  • target beta estimated from calm markets; real beta rises in crashes
  • educational simulation, not investment advice
