Bitcoin keeps losing ground when Wall Street opens as Coinbase discount deepens

Summary

Bitcoin lost 3.24% during US stock-market hours from Sept. 21 through Oct. 7, while gaining 6.07% outside that window. A Coinbase premium measure fell to a $64 discount against Binance, and both exchanges showed broader weakness during US hours. However, two sharp declines drove much of the loss: excluding those sessions, returns were positive when using a 9:30 a.m. start, though results varied with the chosen time window. ETF flows do not establish a clear cause: outflows coincided with one major drop, but inflows accompanied another. The data suggest weaker US-session demand but cannot identify sellers or prove persistent institutional selling.
