Duan Yongping Reconfigures Portfolio: How the Legendary Investor Navigates the AI Revolution

While the entire market debates artificial intelligence, renowned investor Duan Yongping has put real capital into motion. His latest moves reveal much more than simple bets on trends—they demonstrate a carefully thought-out investment architecture designed to capture technological transformation across multiple layers. In the fourth quarter, the value analysis veteran increased his Nvidia holdings by over 11 times, while opening three entirely new positions in companies representing the AI value chain. Simultaneously, he made significant rebalancing in his traditional assets, drastically reducing his largest position in Apple.

The three technology trail: how Duan Yongping mapped the AI value chain

Duan Yongping’s strategy shows a sophisticated understanding of the three pillars of AI infrastructure. His sequence of investments is not random—each move points to a specific and critical segment of digital transformation.

First comes computing power. The investor increased his Nvidia position by 6,639,300 shares in the quarter, an explosive increase of 1,110.62%, bringing the total to 7.2371 million shares valued at $1.35 billion. Nvidia has become the third-largest position in his portfolio, representing 7.72% of the portfolio. But Duan Yongping went beyond the traditional “paddle seller”—he recognized that GPU demand would create a huge secondary market. Thus, he initiated a position in CoreWeave, a company specializing in building and leasing high-performance GPU clusters for AI companies. With 299,900 shares added to the portfolio, CoreWeave represents the next generation of business in the era of scarce computing power.

The second layer is connectivity infrastructure. Duan Yongping started a position of 141,300 shares in Credo Technology, a manufacturer of ultra-high-speed interconnection chips that function as the blood vessels of data centers. While GPUs are the heart of the system, Credo’s optical modules ensure that hundreds of AI servers can communicate at extreme speeds—an absolutely essential requirement for training modern models. This is a lateral bet on the growth of AI servers, capturing revenue from large-scale data center upgrades worldwide.

The third pillar is vertical application in regulated sectors. Tempus AI, with an entry of 110,000 shares, represents a different bet. Unlike the previous two focused on hardware, Tempus applies artificial intelligence to precision medicine, specifically oncology. This is Duan Yongping’s move toward practical AI applications—the point where “computing capacity” turns into “real productivity.” However, since the healthcare sector is highly regulated and cycle-long, this bet will prove to be a marathon, not a short race.

From past to future: Duan Yongping’s strategic rebalancing

While leveraging his exposure to artificial intelligence, Duan Yongping also precisely managed his defensive assets and his largest historical position. Apple remained the largest holding in the portfolio, with a market value of $8.797 billion (50.3% of the portfolio) at the end of the quarter. However, during this period, he sold 2,470,600 Apple shares—a 7.09% reduction. This move may reflect both the need to control risks from over-concentration in a single asset and the need to free up capital to fund new AI bets.

Meanwhile, the defensive asset Berkshire Hathaway B received a significant increase. Duan Yongping bought nearly 1.985 million shares, a 38.24% increase, solidifying Berkshire as the second-largest position with a 20.63% stake. The final structure is eloquent: “technological growth with one hand, value safety with the other.”

In addition to these main moves, the investor also increased his exposure to Google and Pinduoduo, while drastically reducing his stake in ASML—the Dutch lithography equipment giant—with a sale of 87.63% of his shares. This last move demonstrates a critical view of the growth potential of different tech giants in an era dominated by AI.

What Duan Yongping’s moves reveal about the market

Duan Yongping’s reconfigured portfolio tells a story about how an experienced investor rebuilds his holdings amid radical technological transformation. Unlike many who bet only on established names, Duan Yongping identified critical points of scarcity and opportunity throughout the entire AI supply chain. His track record of major wins in NetEase, Kweichow Moutai, and Apple now extends into a new universe: one dominated by artificial intelligence, GPUs, data interconnection, and precision medicine. This investment pattern suggests that the coming decades will belong to infrastructure builders and practical application explorers—precisely where Duan Yongping has positioned his capital.
