A significant rotation is underway in Asian markets, with investors pulling funds from the semiconductor companies that have driven this year's rally. Korean stocks have tumbled as capital flows shift toward Chinese equities, driven by concerns over valuations and a search for cheaper AI-related plays. The move reflects a broader recalibration of expectations around the AI boom.

The rotation, described as a "big market shift" by Bloomberg, comes as jitters spread about the sustainability of the AI-fueled rally in chipmakers. Rather than exiting the sector entirely, investors are reallocating to markets perceived as offering better value. Chinese stocks have surged as a result, benefiting from this capital rebalancing.

Korean stocks have extended their drop from a peak to 20%, according to Bloomberg data. The sell-off has hit the country's major chip producers hardest, as they were among the primary beneficiaries of earlier AI enthusiasm. The magnitude of the decline highlights the speed and force of the current rotation.

The shift suggests that while AI remains a dominant theme, its impact is becoming more nuanced across geographies. For South Korea, the outflow raises questions about its reliance on semiconductor exports to sustain market momentum. For China, the inflow provides a boost amid its broader economic challenges.

Some analysts caution that the rotation may be short-lived if AI demand proves resilient, potentially reversing flows back to Korean markets.
