- • Korean and Taiwanese equities surged 127% and 66% respectively in US dollar terms over the past twelve months, driven primarily by semiconductor heavyweights Samsung Electronics, SK Hynix, and Taiwan Semiconductor Manufacturing Company capitalizing on AI infrastructure spending.
- • Martin Emery, portfolio strategist for GMO's systematic global macro team, argues that elevated corporate investment spending and CEO confidence in the AI boom mirror historical patterns that preceded lower equity returns and recessions, citing research linking higher manager confidence to lower future earnings surprises.
- • GMO assesses both Korean and Taiwanese markets as "particularly expensive" with long-term valuations forecast below the cash rate, suggesting limited upside from current levels despite near-term AI tailwinds.

Summary
GMO's systematic global macro strategy has established a contrarian positioning against the recent artificial intelligence-driven equity boom in Asia, shorting Korean and Taiwanese equities while maintaining a long position in US markets tempered by shorts in US technology stocks. According to Martin Emery, portfolio strategist for GMO's systematic global macro team, the strategy does not take direct stock positions but instead constructs its portfolio around sector and regional themes influenced by macroeconomic cycles, with the current AI investment surge prompting a deliberate defensive stance in Asia's semiconductor-heavy markets.
The thesis underpinning this positioning reflects concern about overinvestment dynamics. Korean equities have appreciated 127% in US dollar terms over the past twelve months, while Taiwanese equities have gained 66%, driven substantially by index-dominant semiconductor firms including Samsung Electronics, SK Hynix, and Taiwan Semiconductor Manufacturing Company. These companies have been primary beneficiaries and suppliers to the global AI infrastructure buildout. However, Emery contends that this pattern of outsized corporate investment and optimistic management commentary echoes previous cycles—such as the dot-com era—that preceded extended periods of lower returns and economic contraction.
Emery cited academic research establishing a negative correlation between elevated corporate investment spending and subsequent equity returns, as well as the predictive power of CEO confidence metrics expressed in quarterly earnings calls. "Higher manager confidence precedes greater investment growth and lower earnings surprises, in aggregate," he noted, suggesting that the current euphoria among AI infrastructure investors may signal a turning point. GMO's valuation framework reinforces this skepticism, with both Korean and Taiwanese markets assessed as trading well above justified levels, with long-term fair value forecasts below prevailing cash rates.
The macro strategy's short exposure to Korea and Taiwan has already generated portfolio headwinds, as documented in recent fund performance notes where these positions detracted from returns during the broader equity rally. This near-term drag reflects the timing challenge inherent in macro-level mean reversion trades, where accurate cyclical diagnosis does not guarantee prompt market repricing. The positioning remains consistent with GMO's historical emphasis on deploying shorts during periods of elevated asset valuations and speculative fervor, particularly when such conditions coincide with measurable indicators of excessive corporate capital deployment.
