Across international equity markets in the second quarter of 2026, AI-related semiconductor names drove Taiwan and South Korea to outperform a mixed field of developed and emerging peers. Against that backdrop, Taiwan Semiconductor Manufacturing Company (NYSE: TSM), the world's largest dedicated chip foundry with approximately 70% market share, raised its revenue outlook after reporting strong demand for its semiconductor manufacturing services, particularly in AI and high-performance computing chips. Diamond Hill Capital's International Fund, a vehicle of First Eagle Investment Management, cited TSM as a notable contributor to performance in its Q2 2026 investor letter.
AI demand and the regional read-through
The demand environment for advanced semiconductors reshaped regional equity flows in the quarter. Taiwan and South Korea pulled emerging markets ahead of developed-market peers. Information technology ranked as the top-performing sector in the period. Europe and Japan posted mixed results: European equities drew support from positive economic indicators and easing inflation, while Japanese stocks advanced on governance reform momentum but were tempered by yen strength and global trade uncertainties. Chinese markets declined.
TSM's revenue guidance increase, which Diamond Hill attributed to demand for AI and high-performance computing chips, reflected the sector-wide pattern. Shares closed at $428.91 on September 4, 2026, a 52-week gain of 73.51%. The one-month return stood at 2.49%, with market capitalization at $1.97 trillion.
Institutional positioning
Broader conviction built through the quarter. At the end of Q2 2026, 249 hedge fund portfolios held TSM, up from 234 the quarter prior. The stock ranked sixth on a compiled list of 40 most popular stocks among hedge funds heading into 2026.
Diamond Hill's International Fund returned 7.76% in the quarter, trailing the MSCI ACWI ex USA Index's 14.49% gain. Stock selection in health care and consumer discretionary contributed positively, but information technology and consumer staples selections detracted from overall results. TSM's guidance raise, the fund noted, came on the back of strong demand for semiconductor manufacturing services tied to AI and high-performance computing.
Diamond Hill's letter flagged narrow market leadership as a challenge for investors focused on undervalued individual companies, with AI-driven concentration in a small number of semiconductor names presenting the central tension. Yen strength and cross-border trade policy uncertainty remain the macro caveats for the sector.
