Diversifiers — Diversification-Adjusted Return ranking

Ranks tickers by DAR = μ / (σ · ρ̄_portfolio) — return per unit of risk, penalized by mean correlation to your existing holdings. Higher DAR = better diversifier-quality at same Sharpe.

[MARKETING-LIKE-pending-Brier-N≥30-validation] per Pre-Launch Validation T0. F183_DAR is in research status; the ranking below is informational. Validation cohort accumulates from per-ticker resolved-claims; flag-flip to live composite scoring is gated on N≥30 portfolio-cohort Brier-improvement vs equal-weight baseline (per v50-BRIER-GATE-V1-RATIFICATION REJECT precedent). Per R9 §12.1: stock-bond correlation regime-shifted positive post-2021; DAR composes-with regime-state classifier — bond-diversification credit is REGIME-CONDITIONAL.

DAR ranks portfolio-fit quality, NOT directional alpha. A high DAR means a ticker improves your portfolio's risk-adjusted return when added (low correlation × decent Sharpe). It is NOT a buy signal. For directional signals see /best-plays; for cross-frame agreement see /confluence.

Methodology

DAR formula: DAR = μ / (σ · ρ̄_portfolio) — μ = annualized expected return; σ = annualized realized volatility; ρ̄ = mean pairwise correlation to portfolio holdings (60d window, floored at 0.01 to prevent ÷0).
Diversifier bonus: DAR / Sharpe — values > 1 indicate the ticker offers ABOVE-AVERAGE diversification benefit relative to its raw Sharpe; values < 1 indicate the ticker is more correlated to portfolio than average.
Portfolio context: ρ̄ is computed against the cockpit Top-Picks universe (proxy for current portfolio when no Plaid holdings detected). Per R9 §12.1: when SPY × TLT correlation flips signs (post-2021 regime shift), Bond-class diversification credit shrinks materially.
HRP integration: DAR composes-with engine/hrp-portfolio.js (López de Prado 2016 4-step Hierarchical Risk Parity). HRP is currently SCAFFOLD-status (THV2_HRP_ENABLED=false default) pending Brier-validation; when activated, DAR-ranked tickers feed into HRP cluster-conditional weights.
What this page is NOT: a tactical buy/sell recommendation. DAR ranks DIVERSIFICATION-quality, not directional alpha. Pair with /confluence (cross-frame agreement) or /best-plays (options-edge) for tactical decisions.
