Stock market today: Dow, S&P 500, Nasdaq mixed as oil prices rise

US stocks were mixed on Friday as investors continued to calibrate to the Federal Reserve's first rate hike in three years and existential fears about artificial intelligence's capabilities.The tech-heavy Nasdaq Composite (^IXIC) rose 0.4% but ended the week in green. Meanwhile, the S&P 500 (^GSPC) rose 0.2% but eked out a loss for the week. The Dow Jones Industrial Average (^DJI) was down 0.2% and lost more than 1.5% for the week. The 10-year Treasury yield (^TNX) rose 5 basis points to hover near the 5% level as traders increased bets that the Fed will raise rates again in October.Markets appeared to look past the Fed's 25 basis point rate hike this week, which was widely expected. US stock continued to climb after the Bank of Japan raised interest rates to the highest level in 31 years.However, analysts and top CEOs aren't convinced that one rate hike (by the Fed) will be enough to bring down stubbornly high inflation. "It's not clear to me we've slayed inflation," JPMorgan Chase CEO Jamie Dimon told Yahoo Finance this week.Oil prices eased below the $100 level, offering some relief as the war in Iran nears its seventh month. The energy shock stemming from disruptions in the Strait of Hormuz continues to baffle analysts and drive inflation higher, complicating the picture for global central banks.Chip stocks, meanwhile, have largely snapped back from a sell-off earlier this week, fueled by calls from Anthropic (ANTH.PVT) and OpenAI (OPAI.PVT) for an AI development slowdown. The PHLX Semiconductor index (^SOX) ended the week up slightly.
