The Nasdaq 100 dropped about 5.5% last week, marking its worst week since April 2025. The Philadelphia Semiconductor Index plunged 11.4%, and Brent crude oil climbed above $110 for the first time since May. In the past, whenever U.S. stocks sneezed, $BTC would catch a cold first. But this time, it held steady at 81k over the weekend, with a final small-scale sweep completed early this morning. Is this a true reversal? We'll find out when U.S. markets open tonight.
