Foreign Money Is Leaving Korea While Taiwan Wins the AI Rotation
Foreign investors had pulled $131 billion from South Korean stocks in 2026 as of October 11, more than from any other major Asian market, according to Bloomberg. That figure is the year-to-date net outflow, meaning overseas sales minus overseas purchases since January 1. It describes a market where the artificial intelligence trade that lifted Korean shares earlier no longer draws overseas buyers.
The relative picture has moved the other way. On October 7, Bloomberg reported that Taiwan had dethroned Korea atop global markets as the AI trade widened (Bloomberg). The shift was visible earlier. In August, Bloomberg reported that global investors favored Taiwanese stocks over South Korean ones after an AI selloff (Bloomberg), and on August 13 the Taipei Times reported the same foreign preference (Taipei Times). Both markets were described in that period as AI bellwethers, meaning benchmark markets whose stocks signal the health of the wider AI sector, recovering from a July downturn.
In the first half of 2026, foreign investors withdrew $137 billion from Asian stocks, according to Reuters. South Korea and Taiwan recorded the heaviest foreign outflows in the region over that period, even though both markets had rallied.
In my view, that combination points to a crowded trade thinning out. The two markets rising fastest were also the ones where overseas money most wanted to leave. Early buyers take profits, and the newest money, the marginal dollar, stops arriving.
Read the August and October headlines with that in mind. A market can be favored over a peer while still seeing net foreign selling. Relative preference tells you where new money is going at the margin. It says nothing about whether the total is positive. A headline about one market dethroning another also squeezes flows, currency moves and index weightings into a single ranking, so the underlying flow data is what matters.
For ordinary savers, the exposure is indirect. Anyone holding a broad Asia or emerging-markets fund owns both markets, and AI-linked hardware names can make up a large share of each index. When foreign flows reverse sharply, those weights can shift faster than the economies beneath them. A fund's country mix and sector concentration can drift from what the holder assumes, so the fund's own holdings report is the place to check.
The sequence runs roughly as follows. Foreign outflows were heavy in the first half. The AI selloff and the July downturn followed. By August, Taiwan was drawing foreign preference over Korea. By October, Taiwan had moved ahead in the broader global ranking, while Korea still reported the largest cumulative foreign withdrawal among major Asian markets.
Taken together, in my reading, the record points to a rotation within the AI trade rather than an exit from it. Whether that rotation lasts is still open. Momentum in relative rankings can reverse quickly if the leading names are re-priced or the crowded positioning unwinds. Weigh the flow numbers, the currency backdrop and each market's earnings exposure separately, rather than treating one headline as a verdict.
