SIGNAL OVERVIEW
Managed money is the discretionary speculator category in both CFTC (Arabica) and ICE Europe (Robusta) commitments-of-traders data. When discretionary speculators are extreme on the same side of BOTH Arabica and Robusta simultaneously, cross-coffee positioning is highly concentrated and future returns tend to run with the stated polarity. The signal takes the product of the two markets’ net managed-money z-scores (3-year rolling standardization) when they agree in sign, and dampens when they disagree. Positive composite equals both long-crowded (bullish setup); negative composite equals both short-crowded. Daily Spearman IC against Arabica forward 60-day returns is plus 0.103 at p-value 2e-13 across 5,066 observations; Phase +1 firings deliver a plus 0.73 pp edge above baseline. Modest 1.45 pp spread; best used as positioning-context overlay.
