Rebound in tech shares pushes world markets higher, while oil prices fall

World shares were mostly higher Thursday, led by tech-driven gains in Japan and South Korea as major computer chipmakers’ stocks surged following upbeat earnings reports from U.S. giants like Qualcomm and Micron Technology. Oil prices slipped closer to where they were before the war with Iran began. Qualcomm’s share price surged nearly 7% in afterhours trading after the company announced it had raised its forecast for revenue this year to $40 billion from $22 billion.
