Global investors hedge as Korea AI-chip rally runs hot but stays intact - CHOSUNBIZ - Chosunbiz

South Korea's stock market has emerged as one of the world's hottest markets during the artificial intelligence boom, with the KOSPI tripling in value over less than 18 months. This extraordinary rally has been driven primarily by semiconductor chipmakers capitalizing on global demand for AI infrastructure and data center buildout, coupled with significant participation from retail investors who have fueled the enthusiasm. SK Hynix and other Korean chip giants have become central to the global AI investment thesis, positioning South Korea alongside Taiwan as a major beneficiary of the worldwide AI spending cycle.

However, the intensity of the rally has prompted a fundamental shift in investor sentiment. A wave of optimism is giving way to growing caution, as institutional investors and hedge fund managers have begun trimming positions and adding hedges to protect against potential corrections. The concern centers on valuation crowding—the rally has become increasingly concentrated and vulnerable to pullback as enthusiasm peaks. Recent sell-offs, particularly among chip stocks like SK Hynix, signal that investors are questioning the sustainability of the gains and attempting to lock in profits before broader market consolidation occurs.

Despite these warning signs, the underlying fundamentals remain compelling for longer-term believers. Peter Kim, global investment strategist at KB Financial Group, asserts that from a valuations and fundamentals perspective, the opportunity is "not even halfway" realized, suggesting potential for continued gains for investors with conviction. The AI engine remains powerful enough to keep global investors engaged, with ongoing demand for chips, data centers, and sovereign AI infrastructure supporting the sector. Historical precedent, however, cautions that when market euphoria peaks, volatility and correction risks intensify—a dynamic that has prompted sophisticated investors to seek downside protection while maintaining exposure to the secular AI trend.

The reshuffling of global stock market hierarchy underway reflects the genuine structural importance of semiconductor supply chains to artificial intelligence deployment. Yet the concentration of gains in a relatively narrow set of Korean and Taiwanese stocks has created the very crowding dynamics that typically precede meaningful pullbacks. Investors are navigating a delicate balance: maintaining participation in what could still be an incomplete AI bull market while hedging against the elevated risk of a significant near-term correction. For hedge funds and institutional investors, this environment demands active risk management and nuanced position sizing rather than outright conviction bets in either direction.
