Duan Yongping, born in 1961 in Nanchang, China, is a big deal in the business world. He's American now. The guy's made waves in tech and investing. Pretty impressive stuff.

He started Subor and BBK Electronics. Not bad. Then came OPPO and vivo. These phone brands? They're everywhere. China, sure, but globally too. It's like Duan's got his fingers in all the pies.

Now, about his investing. Duan's all about value. He spots undervalued gems and holds on. Patience pays off, it seems. Take NetEase. He jumped in early, back in 2001. The returns? Mind-blowing. We're talking 100 times his initial investment.

As of 2025, Duan's portfolio is huge. $18.2 billion in US stocks. Apple's his favorite child, making up 78% of the total. That's $14.2 billion right there. Kind of risky, maybe?

But he's not a one-trick pony. Berkshire Hathaway, Google (or Alphabet now), Alibaba - they're all in there. He's got energy stocks, entertainment, even pharma. Bank of America too. Diverse, you know?

Recently, he's been tweaking things. Sold some Apple, bought more Alibaba and Occidental Petroleum. Market trends, perhaps? Or just gut feeling? Hard to say. Moderna's still there, unchanged. Biotech's future looks bright to Duan, apparently.

It's not all about money, though. Duan's into giving back. He's donated big to schools. Zhejiang University got a nice chunk. Education matters to him, it seems.

Duan Yongping's story? It's inspiring. Business smarts meet disciplined investing. A recipe for success, not entirely clear how he does it. But it works. He's setting the bar high, that's for sure.
