Duan Yongping's H&H Portfolio: Unwavering Focus on Tech Giants
Duan Yongping's H&H International Investment portfolio, as of December 31, 2025, remains heavily concentrated in top holdings like Apple and Berkshire Hathaway.

Top Holdings Analysis
H&H International Investment's portfolio, managed by Duan Yongping, exhibits extreme concentration, with the top two holdings accounting for a significant portion of the total value. Apple Inc. (AAPL) stands as the largest holding, representing approximately $8.8 trillion in value, which translates to about 50.3% of the total portfolio. This massive allocation underscores a core focus on the technology sector. The second-largest holding is Berkshire Hathaway Inc. (BRK-B), valued at nearly $3.6 trillion, contributing 20.63% to the portfolio. These two stocks alone represent over $12.4 trillion, highlighting the portfolio's heavy reliance on a select few technology and financial services giants.
Other significant holdings include NVIDIA Corporation (NVDA), valued at $1.35 trillion (7.72% allocation), and PDD Holdings Inc. (PDD), valued at $1.31 trillion (7.48% allocation). The portfolio also includes substantial positions in Alibaba Group Holding Ltd. (BABA) ($0.38 trillion, 2.15%) and Micron Technology Inc. (MSFT) ($0.42 trillion, 2.38%). These top holdings demonstrate a clear preference for large-cap technology and consumer cyclical companies, with a notable emphasis on growth stocks like Apple and NVIDIA.
Sector Concentration
The portfolio's sector allocation reveals a strong bias towards Technology and Consumer Cyclical sectors. Technology is the dominant sector, encompassing Apple (AAPL) and NVIDIA (NVDA), with a combined allocation of 58.02%. This sector allocation is driven primarily by the massive weight of the Apple position. Consumer Cyclical is the second most prominent sector, including PDD and BABA, with a combined allocation of 9.63%. Financial Services, represented by Berkshire Hathaway (BRK-B), holds a substantial 20.63% allocation, making it the second largest sector allocation after Technology. Energy (OXY) and Communication Services (GOOG, DIS) round out the significant sectors, each holding allocations of 3.10% and 3.79% respectively.
Investment Strategy and Changes
Duan Yongping's investment strategy appears to be centered on acquiring and holding large, established technology companies alongside a significant stake in Berkshire Hathaway. The portfolio shows notable changes in certain holdings. NVIDIA Corporation (NVDA) experienced a dramatic increase in its position, with a 1110.62% increase in shares during the period, indicating strong confidence in the company's growth trajectory. Conversely, Apple Inc. (AAPL) saw a slight decrease in its share count (-7.09%), though its overall allocation remains colossal. Other changes include a notable increase in Micron Technology Inc. (MSFT) (+207.66%) and PDD Holdings Inc. (PDD) (+34.55%), while Alibaba Group Holding Ltd. (BABA) saw a decrease (-7.81%). The investment approach seems focused on capturing significant gains from leading technology and e-commerce players, while also leveraging the stability of Berkshire Hathaway.
The portfolio's structure suggests a long-term growth strategy, heavily weighted towards technology and consumer-facing businesses. The significant allocation to Technology (58.02%) and Consumer Cyclical (9.63%) indicates a belief in the continued dominance and growth potential of these sectors. The inclusion of Berkshire Hathaway (BRK-B) at 20.63% allocation adds diversification within the Financial Services sector and aligns with a value-investing philosophy, albeit alongside the massive technology bets. The strategy appears to favor conviction plays on select high-growth and established leaders, accepting high concentration as a core tenet of the investment approach.
