TSMC, Samsung and SK Hynix Swell to Nearly 33% of MSCI Asia, Forcing Fund Sales

Summary
Three AI chip giants now make up almost a third of MSCI's Asia Pacific ex-Japan index, leaving active managers such as Jupiter's Sam Konrad selling top performers despite gains of 52% in TSMC, 159% in Samsung and 184% in MediaTek.
That concentration has turned key benchmarks into narrow AI bets: TSMC accounts for 41.5% of Taiwan's TAIEX, while Samsung and SK Hynix make up 55% of South Korea's KOSPI.
HSBC says TSMC is the biggest underweight position among Asian and global emerging-market funds, creating a cycle in which rising share prices force managers to trim exposure and fall further behind benchmarks.
The distortions are spilling into markets and flows, with South Korean stocks down 12% and Taiwan down 6% in the last three sessions from record highs, while rebalancing helped drive a record $27.9 billion outflow from Korean equities in May.
Asia's concentration is now more extreme than the U.S. Magnificent Seven effect, accelerating the shift to passive investing as active funds lost $269 billion over five years and passive funds drew $510 billion.

The 2026 Asian Equity Surge: AI-Driven Concentration Hits Historic Highs, Led by TSMC, Samsung, and SK Hynix
Overview
Asia's equity markets in May 2026 are marked by an unprecedented level of concentration, driven by the booming artificial intelligence sector. This trend has accelerated even faster than the 'Magnificent Seven' phenomenon in the US, transforming regional indices into highly concentrated bets on just one or two dominant stocks. As a result, the traditional diversification benefits of benchmark investing are diminishing. The overwhelming influence of Taiwan and South Korea, both showing robust economic and earnings growth, defines this new landscape. Investors now face a market where AI leaders dominate, making active management crucial to navigate emerging risks and opportunities.
