Composites
Portfolio simulator
Search and add published strategies, then choose how to weight them.
Duquesne×H&H International×Citadel×
Some of the selected funds file only their US long positions, so the combined result covers just that part.
EqualRisk parityMean-var
Each strategy gets the same weight — simplest, no estimation.
Top 10Top 20>1% all
Combine the selected funds' holdings into one portfolio, keep only the largest positions after combining, and backtest it (vs SPY) — change how many holdings are kept and the result changes.
From earliestAll present
"From earliest": start from the earliest fund with data; the rest enter when they join. "All present": start only once every fund has data.
CompoundFixed
Gains are reinvested — principal and returns grow together.
