DWF Labs Finds US Spot Bitcoin ETF Flows Lag Price Moves, Lack Predictive Power

U.S. spot Bitcoin ETF flows serve as reactive, lagging indicators rather than predictive price signals, according to research by DWF Labs covering 694 trading days through October 16, 2026. Capital consistently chased momentum, showing a 0.54 correlation with Bitcoin returns over the preceding five sessions, but just 0.03 over the following five days. Funds recorded net outflows across seven of eight major sell-offs of 15% or more, with redemptions peaking days before price bottoms in five instances. Inflows occurred across all nine rallies of at least 15%, while roughly 20% of flows reflected hedged basis trades.
