DWF Labs research finds that Bitcoin ETF flows follow past BTC price movements rather than predict future returns, with investors buying rallies and selling dips.
US spot Bitcoin exchange-traded fund (ETF) daily flows aren’t reliable guides to BTC’s next move as investors tend to chase rallies and sell into slumps, according to DWF Labs.
In a research report published Thursday, DWF found that investors pulled money from the funds during seven of the eight times Bitcoin’s price dropped at least 15%. All nine rallies of that size drew net inflows. The analysis reviewed 694 trading days dating back to January 2024, when Bitcoin ETFs first launched in the US.
“ETF flows confirm moves; they don’t predict them,” DWF said in its report. “The evidence points mostly to investors reacting to price, not driving it.”
Investors tended to put money into Bitcoin ETFs after prices rose and pull it out after prices fell. Those flows offered almost no clue to whether Bitcoin would rise or fall over the next five days.
Each day’s ETF flows had a moderate relationship with Bitcoin’s price changes over the five trading sessions before that day, with a correlation of 0.54. On a scale where zero means no relationship, the correlation for the following five days was 0.03.
The heaviest withdrawals came during the two most recent sell-offs. Investors withdrew a net $6.9 billion between October 2025 and February 2026, followed by $8.2 billion during the May–June decline.
The figures do not show whether institutions or retail investors drove the selling.
