Masayoshi Son, SoftBank Group Corp.’s billionaire founder, checks the chart. Then again. Another time. And once more for good measure.
Lately it’s only moved in one direction: up.
It’s not a chart of the firm’s stock picks. Those are sinking fast. So too is Son’s fortune — at $13.7 billion (¥1.6 trillion), it’s crashed $25 billion in the past year, according to the Bloomberg Billionaires Index.
