TOKYO (AP) — Japanese technology company SoftBank Group Corp. racked up a huge loss in the July-September quarter as its technology investments, most notably office-sharing company WeWork, went sour. Tokyo-based SoftBank loss totaled 931 billion yen ($6.2 billion) in the last quarter, a reversal from the 3 trillion yen profit it posted in the same period a year earlier. SoftBank has a sprawling investment portfolio and tends to have erratic financial results that fluctuate with market trends.
