AI Hardware Concentration Triggers Emerging Market Stock Rout

Emerging market stock indexes are experiencing extreme volatility following a surge driven by the artificial intelligence boom. The concentration of AI hardware firms has left markets top-heavy, with nine companies—including Chinese tech giants Alibaba and Tencent alongside hardware firms from Taiwan and South Korea—now accounting for over 40% of the MSCI EM index.

MSCI Inc. reports that this concentration has reduced the diversification value of emerging markets, aligning them closely with the AI hardware cycle. This shift has led to significant losses; South Korea's KOSPI index dropped 40% in six weeks, and Taiwan's TSMC saw its share price fall nearly 14%.

International investors have responded by withdrawing capital from Asia-ex China markets at the fastest rate since 2010. Data from Chase Bank indicates that South Korea and Taiwan lost over $100 billion and $44 billion respectively during the first half of the year.
