Treasury said it would at least double buybacks of 10- to 30-year debt, but the relief faded within 48 hours as the 30-year yield returned to 5.25%. Bitcoin rose from about $63,000 to above $77,000, a roughly 23% weekly gain, helped by the bond-market move, President Donald Trump's support for the Clarity Act and a record $2.7 billion liquidation of bearish crypto positions. Walmart fell 9.2% despite better-than-expected quarterly results and higher full-year guidance, as a $2.9 billion tariff refund boosted the comparison and third-quarter earnings guidance missed estimates. The S&P Global U.S. Flash Composite PMI (business activity survey) rose to 56.0, indicating the fastest expansion since April 2022. Moderna led weekly S&P 500 gainers after its Merck-partnered personalized mRNA melanoma vaccine succeeded in a Phase 3 trial, while Coinbase and Estée Lauder also posted strong gains.
