US stocks advanced in the first full trading session after the Federal Reserve's rate hike, with the Nasdaq Composite rising 1.69%, or 439.88 points, to 26,418.30. The S&P 500 gained 1.14% to 7,637.76, while the Dow Jones Industrial Average added 0.61% to 51,778.04. Lower Treasury yields eased discount-rate pressure on high-valuation growth stocks and helped the Philadelphia Semiconductor Index surge 3.14%, led by Intel, AMD, SanDisk and Micron Technology. Initial jobless claims fell to 196,000 for the week ended September 12, while pending home sales rose 0.3% in August but remained 4.7% below year-earlier levels. Oil prices declined for a second session but stayed above $100 a barrel, with shipping risks near the Strait of Hormuz remaining a key concern. Gold and silver posted modest gains, Chinese ADRs were mixed, and investors shifted attention from the rate decision toward oil prices and bond yields.
