[CONSOLIDATED] Macro-Filtered Sector Momentum Beats Naive Extrapolation | Sector momentum and rotation models must combine multi-timeframe trend alignment, risk-adjusted momentum, cross-sectional dispersion z-scores, and explicit macro regime filters—factor sensitivities (duration, credit, liquidity, rate), yield curve and liquidity velocity—since naive momentum extrapolation collapses to 0.0% directional hit rates in high-rate, tight-financial-conditions regimes. Robust sector selection instead requires forward-looking industry catalysts and newsflow liquidity trends, plus fundamental resilience screens that penalize rate-sensitive, low-margin discretionary plays facing mortgage rate shocks and multiple contraction while favoring cash-flow-robust sectors, avoiding flat, ungrounded positioning.
