TOKYO, May 13 (Reuters) - Japanese technology giant

SoftBank Group ( SFTBF ) swung to a quarterly profit on Monday,

reporting a net profit of 328.9 billion yen ($2.11 billion) for

the January-March period.

The Vision Fund investment unit booked an investment loss of

57.5 billion yen, after three consecutive quarters of profit.

The net profit at group level compared with a 32 billion yen

loss in the same period a year earlier, when capital raised

using SoftBank's stake in Alibaba Group ( BABA ) cushioned some

of the writedowns in the value of Vision Fund private portfolio

companies.
