The ‘Chinese Warren Buffett’ increases his stake in Nvidia stock by 1,000%

Duan Yongping, a renowned investor and entrepreneur known as ‘the Chinese Warren Buffett,’ has submitted his fourth-quarter 2025 13F filing, offering a detailed snapshot of his most recent portfolio.

The disclosure shows an interesting mix of aggressive position increases and selective trims, illustrating in particular Yongping’s conviction in artificial intelligence (AI) and blue-chip names.

A rather notable was the dramatic increase in Nvidia (NASDAQ: NVDA), as the H&H International Investment manager had added no less than 6,639,300 NVDA shares to his portfolio, lifting his total stake to 7,237,100 shares (around 7% of the portfolio).

This marked a 1,110.62% surge in the overall share count and the value of the position to approximately $1.35 billion.

The third largest addition was Tempus AI (NASDAQ: TEM), with 110,000 shares valued at $6.50 million.

Major position increases included Berkshire Hathaway’s (NYSE: BRK), adding 1,984,896 shares. That brings his total holdings to 7,176,196 shares, marking a 38.24% increase and a position valued at roughly $3.61 billion.
