After a 25% Wipeout, South Korea's Turmoil May Finally Be Easing

Foreign buying finally reversed the flow

The cleanest read is a flow reversal, not just a bounce. Foreign investors bought a record $5.4 billion of South Korean stocks on Friday after selling roughly $110 billion of Korean stocks earlier in 2026. After that sustained exit, real money turning back is the first sign the washout may be ending.

The next few sessions matter. One surge can be impulse buying, but after a massive foreign selloff it often signals that global allocators are testing whether the panic has worked through the market. Reuters described Friday as the largest daily purchase on record, and another report said it was more than double the previous one-day record. If foreign inflows remain positive for several sessions, the rebound can extend because the new bid is coming from outside a broken domestic mood.

The setup is also more responsive because much of the old leverage has already been flushed out. The KOSPI is down about 25% from its record closing high. That does not end a bear market on its own, but in a market driven by positioning and liquidity, a sustained foreign bid is usually the first sign of price support.

Why the selloff turned into a panic

The intensity mattered as much as the direction. Foreign selling was concentrated in Kospi Tech and Auto outflows, with about $62 billion offloaded by late May. That mattered because South Korea's rally had also become concentrated. As the biggest weights rose, some active managers had to trim positions to stay within portfolio and risk limits, turning strong stocks into forced supply.

Leverage made the drop self-reinforcing

One session showed the benchmark Kospi plunging more than 8% at the open. Another session showed foreign investors accelerated their withdrawal and drove the Kospi down more than 5%. That combination suggests the selloff was amplified by liquidity and leverage, not just a slow fundamental repricing.

The bull case: a mechanical reset, not a fundamental break

If the panic was mainly mechanical, the rebound case improves as leverage unwinds. Reuters reported that the move was a leverage event, not an earnings event. That leaves open the bull argument that the market cleared weak positions and forced sellers, rather than fully breaking the underlying corporate story.

The bear case: one rebound day is not enough

Bears do not need to prove that fundamentals broke. They only need to show that one reversal day is not the same as a durable inflow trend. Until foreign buying continues, this can fairly be called a relief trade rather than a confirmed turn.

What would confirm the turn

The turn becomes more credible only if Friday's inflow becomes a pattern. Foreigners bought a record $5.4 billion of South Korean stocks on Friday, but one session is a signal, not proof. The practical test is simple: watch whether the market becomes steadier over the next several sessions.

Bulls will look for persistent foreign buying, lower volatility, and signs that the market is absorbing supply without another sharp flush. Bears will argue that the de-risking trend is not over until foreign flows stay positive for longer than a single session. That is the key decision point now: one green day suggests turmoil may be easing; a series of constructive sessions would make that case stronger.
