Core Viewpoint - Stanley Druckenmiller has shifted his investment focus from Nvidia and Palantir to Taiwan Semiconductor Manufacturing Company (TSMC), indicating a strategic pivot within the AI sector as he seeks to capitalize on different opportunities in the technology landscape [5][15]. Investment Activity - Druckenmiller's Duquesne Family Office sold all shares of Nvidia (9,500,750 shares) and Palantir (769,965 shares) between June 30, 2023, and March 31, 2025, respectively [9][12]. - In contrast, during the March-ended quarter, Druckenmiller purchased 491,265 shares of TSMC, increasing his stake by 457% from the end of December [15]. Company Performance - Nvidia's stock has surged by 827% since the beginning of 2023, while Palantir's shares have skyrocketed by 1,920% during the same period [6]. - TSMC is integral to the production of chips for AI-accelerated data centers and is expanding its chip-on-wafer-on-substrate (CoWoS) capacity from 35,000 monthly units in 2024 to an expected 135,000 units by 2026 [16]. Market Dynamics - Nvidia faces increasing competition as many of its largest customers are developing their own AI-GPUs, which could impact its pricing power and gross margins [10]. - Palantir's valuation is under scrutiny, with a price-to-sales (P/S) ratio of 103, significantly higher than historical norms for companies leading in innovation [13]. Diversification and Risk - TSMC's operations are diversified beyond AI chips, producing components for smartphones, wireless devices, and next-generation vehicles, which may mitigate risks associated with a potential AI bubble [18]. - The company is also navigating uncertainties regarding tariffs, particularly as it maintains significant production in Taiwan despite a new facility in Arizona [19]. Valuation Considerations - TSMC's forward price-to-earnings ratio of 18 appears reasonable, but its shares are valued at over 10 times trailing-12-month sales, representing a 16% premium to its average P/S multiple over the last five years [20].
