IS/OOS 2016-01-01, sqrt(365), 501 equity names. Independence = corr to EqMom + corr to market + market-neutral residual Sharpe. A real NEW edge = positive OOS Sharpe, p<0.05, AND (low corr to EqMom OR residual Sharpe>0).

Reading

  • Residual momentum strips market beta before ranking: if its residual Sharpe>0 it is NOT the same factor as EqMom (which is raw momentum).
  • BAB (low-beta long / high-beta short) is a documented real anomaly; by construction it has LOW corr to the market. The long-only slice is the deployable, no-short diversifier.
  • TOM is a calendar timing overlay ON the market (corr~1 to market) -> not a new factor, only a seasonal tilt; useful as an overlay, not a sleeve.
  • Cost note: top-decile monthly rebalance at 10bps/side is already ~2.4% drag/yr; BAB long/short is far costlier (2x turnover) and needs shorts.

Caveats

  • Annualization uses sqrt(365) (house crypto convention). For these EQUITY daily returns the finance-standard is sqrt(252); the reported Sharpes are therefore ~20% OVERSTATED vs a 252-day basis. Cross-round ranking is unaffected (all Rounds use sqrt(365)), but do not compare directly to quant-site/backtester figures that use sqrt(252) without rescaling.
