US stocks fell for a fourth straight session on Thursday, the 10th, as escalating conflict in the Middle East pushed oil above $100 a barrel and August producer-price data reinforced expectations of higher interest rates. The Dow Jones Industrial Average fell 0.60% to 52,064.10, the S&P 500 declined 0.58% to 7,591.70 and the Nasdaq Composite lost 0.65% to 26,081.73. The Philadelphia Semiconductor Index dropped 2.66%, ending a five-session advance, while Nvidia, Micron, Intel, Lam Research, AMD, ASML and TSMC's ADR all fell. Apple bucked the trend with a 3.6% gain after unveiling its $1,999 iPhone Duo, while Oracle shares rose more than 7% after strong quarterly results and cloud growth. August PPI increased 0.4% month over month and 5.4% from a year earlier, above the 5.3% forecast, while core PPI rose 4.6% annually. West Texas Intermediate crude approached $103 and Brent crude neared $109 as conflict disrupted shipping routes through the Strait of Hormuz and the Red Sea. Treasury yields also climbed, with the 10-year yield briefly nearing 5%, the 30-year yield reaching 5.3% and the two-year yield rising nearly 15 basis points. CME FedWatch odds of a quarter-point increase at the Federal Reserve's September 15-16 meeting rose to 71%-75%, while traders fully priced at least one increase by the end of October. Investors will focus next on Friday evening's August CPI data, which could either reinforce rate-hike expectations or ease market pressure if inflation cools notably.
