SoftBank Group Corp. said Friday it posted a net loss of ¥129.10 billion ($895 million) for the six months ended September, a reversal from a net profit of ¥363.57 billion it recorded in last year's fiscal first half, as its investment business was hit by a market slump.

Its net loss, however, reduced from a record ¥3.16 trillion in the April-June quarter after it logged massive gains from selling some of its stake in Chinese tech giant Alibaba Group Holding.

In the first half of the current business year, SoftBank Group reaped ¥3.5 trillion from the sale of Alibaba shares, although that was not enough to offset a loss of ¥4.4 trillion from its Vision Fund business.
