Stock market today: Big Tech rebounds and oil prices rally in a frenetic day for financial markets

Big technology stocks are bouncing back and boosting U.S. indexes, just one of the many swings for financial markets around the world. The S&P 500 rallied 1.2% Wednesday. The Dow added 55 points, and the Nasdaq composite jumped 1.8%. A stronger-than-expected profit report from Advanced Micro Devices helped drive chip stocks. Oil prices jumped after the death of Hamas’ political leader raised worries about the flow of crude, while the yen strengthened after the Bank of Japan raised its benchmark interest rate. Treasury yields eased by a bit ahead of a decision on rates by the Federal Reserve coming in the afternoon.
