TOKYO — SoftBank, operator of the world’s largest tech fund, said on Monday that it would sell as much as $41 billion in assets as it seeks to vacuum up its own shares, which have dropped precipitously in the last month amid investor concerns about the coronavirus outbreak.

SoftBank has used its $100 billion investment fund to bet heavily on companies offering services, such as hailing rides and booking hotels, that are likely to take a significant financial hit as consumers stay home.

In a statement released Monday morning, SoftBank said it would use 2 trillion yen ($18 billion) from the sale of its assets to purchase its own shares over the next year. The amount is on top of a ¥500 billion buyback announced earlier this month.

Taken together, the company could retire as much as 45 percent of its outstanding stock, it said. The rest of the money will be used to pay down its debt and shore up its cash reserves.
