Point return formula (linear factor model):
r_hat = alpha + sum_i (w_i × f_i)
where w_i is the cross-sectional loading for factor i
(estimated from the cross-section of US large-cap names) and f_i is the
z-scored factor value for this ticker (Grinold-Kahn winsorization at ±3).
Per-factor contribution shown in the waterfall above is exactly
w_i × f_i (decimal-return units), so the bars sum (with intercept) to
the linear forecast point. The ensemble point combines linear / Monte Carlo /
AR(1) / random-walk per per-method-comparison table.
Bias mapping (composite z-score → LONG/NEUTRAL/SHORT): weighted sum of value (1.0), quality (0.7), momentum (1.0), low-vol (0.5), revisions (1.0), news-activity (0.6); thresholds ±1.0 with macro override (risk-off + LONG → reduce to NEUTRAL; risk-on-growth + SHORT → reduce to NEUTRAL). LONG → Playbook A (long-call / call-debit-spread / covered-call); SHORT → Playbook B (long-put / put-debit-spread / bear-call-spread); NEUTRAL → cash.
Sensitivity (one-factor-at-a-time tornado above): impact = w_i × 1sd
per factor (MSCI / Two-Sigma Venn convention). Stress scenarios are canned multi-factor
shocks (rates +100bps; recession risk-off; quality flight).
Factor decay uses exponential half-life per factor type:
catalysts 7d, news 14d, revisions 30d, momentum 45d, value 90d, quality 90d
(Tetlock 2007; Cohen-Malloy-Pomorski 2012). The heatmap above shows
contribution × exp(-ln(2) × t / half_life) on a 5-day grid.
Factor IC backtest: Spearman rank correlation between each factor's
cross-sectional ranking on day t and the realized h-day-forward
return, aggregated across the panel (Grinold-Kahn 2000 ch.4 fundamental law of
active management). Source for this report: synthetic_panel_252d_100tickers_seed42 (parallel runner).
