TOKYO -- Shares in SoftBank Group opened lower in Tokyo on Tuesday after the Japanese tech group said it expected to book its biggest ever annual loss, sparked by a reduction of 1.8 trillion yen ($16.7 billion) in the value of its investments at its $100 billion Vision Fund,
The steep loss at the fund follows a troubled year when the near-collapse of the WeWork shared office space business, one of the fund's highest-profile investments, cast a shadow over Softbank and its CEO, Masayoshi Son.
