The U.S. stock market rebounded after three weeks of losses, with Nvidia's earnings and Jerome Powell's speech causing some volatility. The AI industry helped offset rising bond yields. Next week, the release of the inflation index and employment report will test the market's recent gains. Powell stated that the Fed is prepared to raise interest rates further, but uncertainty remains about the need for more rate hikes. Annual U.S. inflation is expected to rise to 3.3% in July.
