Shares were mostly higher Thursday in Asia, 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 fell more than $1, bringing them closer to where they were before the war with Iran started. Qualcomm’s share price surged 12% in afterhours trading after the company announced it had raised its forecast for revenue this year to $40 billion from $22 billion.
