ETF-Flow Residualcheck — Momentum vs. genuiner Edge

Dropped
2026-05-19 etfauditmomentumresidualdirectional
Hypothesis
Wenn das ETF-Flow-Signal aus Exp #18 (IC +0.37) hauptsächlich BTC-Daily-Momentum ist, bleibt nach Residualisierung auf den pre-release Return (22:00 UTC Marker) wenig übrig (IC < 0.05). Bleibt residual_IC > 0.20, ist ETF flow ein genuiner directional Edge.
Verdict
**MOMENTUM-ARTEFAKT** — Residualisierter IC = +0.0754 kollabiert vs Original +0.0445 (Drop -69.6%). Der vermeintliche ETF-Edge war fast ausschließlich BTC-Daily-Momentum. ETF-Flow Feature bringt keine unabhängige Information über ret_pre hinaus.

Approach

Marker = 22:00 UTC daily close (NY-Close, ETF-Release-Moment). Construct three returns:

  • ret_pre(t) = log(close_t_22:00) − log(close_{t−1}_22:00) — alles vor Release
  • ret_fwd(t) = log(close_{t+1}_22:00) − log(close_t_22:00) — alles nach Release
  • flow_t = Farside aggregated net flow daily

Pooled ICs aller paarweisen Beziehungen plus eine OLS-Residualisierung von flow_t auf ret_pre. Wenn das daily BTC-Momentum (ret_pre) den größten Teil der Cov(flow, ret_fwd) erklärt, kollabiert IC(flow_residual, ret_fwd).

ret_pre → ret_fwd (daily momentum baseline) -0.0431 -0.1201 0.0397 0.291 602
flow_residual → ret_fwd (orthogonal zu ret_pre) 0.0754 -0.0052 0.1524 0.0644 602

Decomposition statistics

  • OLS β (flow_t per unit ret_pre): +4995.28 US$m per log-return unit

  • OLS α (intercept): +91.82 US$m

  • R² of flow explained by ret_pre: 16.40%

  • Residualisation drops IC by -69.6% (+0.0445 → +0.0754)
