Deutsche Bank strategist said Microsoft’s strong results triggered a global tech rebound, lifting the Nasdaq and semiconductor stocks and helping the S&P 500 record its best single-day performance in seven weeks despite weak breadth. Amazon’s robust cloud growth offset disappointing guidance from Apple. South Korea’s composite stock index (KOSPI) jumped 16.4% and Japan’s Nikkei Index rose more than 4%.
