U.S. stocks closed higher Friday on solid economic data, with the Dow Jones Industrial Average gaining about 1% and the Nasdaq Composite ending a five-day losing streak, although all major indexes recorded weekly declines. Investors contended with sharp Treasury-yield swings and developments in the Middle East. Next week, markets will confront four major variables: details of new U.S. sanctions on Iran, Federal Reserve Chair Kevin Warsh's first address at the Jackson Hole Economic Symposium, July core PCE inflation data and Nvidia earnings. Spot gold rose above $4,600 an ounce, or approximately NT$150,000, for a third straight weekly gain and reached $4,632.14 intraday Friday. Its advance reflected U.S. debt-sustainability concerns, a softer dollar and the Treasury's surprise decision to at least double its buyback program for 10- to 30-year Treasuries. Oil flows through the Strait of Hormuz have nearly stopped amid the escalating U.S.-Iran standoff, while Brent crude gained 6.39% for the week and approached $100 a barrel, or approximately NT$3,200. Investors will also assess whether Warsh offers a clearer monetary-policy framework, whether July core PCE inflation changes expectations for a September rate decision and whether Nvidia can support the S&P 500's potential move toward 8,000.
