Hedge fund founder Jonah Cheng called Nvidia the most successful investment of his career. But now, he has sold his last batch of Nvidia shares and questioned the future of the $3.5 trillion chip giant. Captain Global Fund, a fund owned by the former UBS Group analyst, focuses on the technology sector and achieved a 42% return last year. The fund is one of many beneficiaries of Nvidia's soaring stock price over the past decade. When Jonah Cheng founded the fund in 2016, Nvidia was one of the first stocks he bought, and since then he has invested more than once.
