Build a portfolio and run it.
Pick tickers and weights on the left, choose a horizon, and compare strategies side by side.
Growth
Drawdown
Decline from the previous high — how deep the holes get, and how long they last.
Results
Best value in each row is marked. Returns are time-weighted unless noted.
Projection
Thousands of possible futures, built by reshuffling this portfolio's own history in quarter-long blocks. This is not a forecast. It assumes the future resembles a rearrangement of one particular stretch of the past — if the next decades differ in kind rather than in order, none of this applies.
Rolling returns
Annualized return of every holding period of this length, not just the one starting on your chosen date. The spread shows how much the result depended on when you happened to buy.
Return by calendar year
Partial first and last years are shown faded.
