BlockBeats news, October 22 — Crypto market maker DWF Labs released a research report pointing out that daily fund flows into U.S. spot Bitcoin ETFs are not a reliable indicator for predicting BTC's next move, as investors tend to chase rallies and sell into declines. The study reviewed 694 trading days since the ETFs launched in January 2024 and found that in 8 instances where Bitcoin's price fell at least 15%, outflows occurred 7 times; while all 9 rallies of the same magnitude recorded net inflows. Data shows that same-day ETF flows had a correlation coefficient of 0.54 with BTC price movements over the past 5 trading days, but only 0.03 with movements over the following 5 days. The report's conclusion is that "ETF flows confirm trends, not predict them."
In terms of specific fund changes, outflows were most severe during the two most recent major sell-offs. Between October 2025 and February 2026, investors withdrew a net $6.9 billion, followed by another $8.2 billion in outflows during the subsequent May-June decline. DWF noted that the data cannot distinguish whether selling came from institutions or retail investors, and estimated that about one-fifth of flows may be hedging trades that buy ETF shares while shorting CME futures to capture spreads.
Additionally, the report found that since the ETFs launched, Bitcoin has experienced about 3 sell-offs of over 15% per year, down from about 4 in 2022-2023 and 8 in 2021. The sell-off process has become smoother, with a median decline of 21.3%, compared to 19.4% during the same period in 2022-2023. This change is not entirely attributable to the ETFs, as volatility and sell-off frequency had already begun declining before the ETFs launched in 2024.
