HypothesisVerdictKey StatisticsInterpretation
H1 — Information Advantage
Foreign futures positioning leads next-day returns
Partial IC(t+1) = −0.133, p = 0.095
Direction Acc. = 56.2% (p = 0.114)
Direction & sign consistent with theory. Borderline significance due to n=161 (8 months). Requires n≥250 to confirm at 5%.
H2 — Time-Varying Predictability
Information advantage varies by market regime
✅ Supported Bull IC = +0.009 · Ranging IC = −0.237
FAI autocorr(1) = 0.941
Bull vs. Ranging IC gap is sharp. High autocorr confirms time-varying structure. This is the core novelty of the FAI design.
H3 — Gradual Price Discovery
IC peaks at t+3~t+5, not t+1 (Kyle 1985)
❌ Not Supported IC(t+1)=−0.133 · IC(t+5)=−0.102
Fisher z p = 0.789
IC weakens t+1→t+5 (reversal vs. prior n=175 run). Bull-heavy sample (66%) masks medium-horizon signal. Re-test when ranging n≥50.
H4 — Contrarian Profits
sign(−FAI) strategy generates excess return
Conditional Full SR = 1.07 (t = 0.84, p = 0.40)
Ranging SR = 3.19 (n = 48)
Full-sample statistical significance weak. Ranging-regime economic significance strong. Supports regime-conditional deployment.
⚠ Sample composition: Bull 107 (66%) · Ranging 49 (30%) · Bear 5 (4%). Bear-regime validation insufficient. All results should be treated as preliminary pending n≥250 accumulation.
