Multi-Symbol Portfolio Backtest

Score-weighted blend of the top radar-eligible strategy/symbol pairs. Legs share a calendar via date intersection and are combined in $1-unit returns space, then scaled to the initial capital.

score-weightedbuy-and-hold within legsbenchmark SPYAll legs use real Yahoo daily OHLCV data.
Methodology / Assumptions
  • Weights are proportional to radar score, with equal-weight fallback if scores are not usable.
  • Effective bets and correlation are computed from daily return series on the shared calendar.
  • Benchmark comparison uses SPY or the first available substitute on the same dates.
  • Portfolio results are historical research diagnostics and do not imply future P&L.

Methodology
  • • Eligible legs: radar candidates and continue-observing strategies with Sharpe > 0.5, capped at four.
  • • Legs the concentration gate flagged as near-duplicates (> 80% return correlation with a higher-ranked leg) are excluded — the portfolio reuses the same diversification decision as the paper-trade queue.
  • • Effective bets = N / (1 + (N−1)·ρ̄), the same N_eff measure shown on the radar panel and home overview.
  • • Weights are proportional to the composite radar score; falls back to equal-weight if all scores are non-positive.
  • • Calendar = intersection of every leg's equity-curve dates so the blend uses only days when all legs traded.
  • • Each leg's equity is normalized to a $1 base; the portfolio re-aggregates daily — no intra-day rebalancing assumption.
  • • Benchmark is SPY (or the first available substitute) sampled on the same calendar.
  • • Correlation cells use Pearson on daily returns; the off-diagonal average drives the diversification badge.
