South Korea's stock market staged a "bull market scare" today: opening up 2%+, dropping straight down 5%, and closing the session narrowed to a 2.3% decline, with a single candlestick breaking through the bullish belief.

The trigger was absurd—the presidential office official mentioned on social media a "national AI dividend," implying that since AI is earning so much, maybe everyone should get some money. The market instantly interpreted this as "targeting profits of Samsung and SK Hynix," and foreign investors sold off without hesitation, net selling about $3.76 billion throughout the day.
It wasn't until an official urgent clarification that "that's not what it means" that the decline narrowed.
But a straw can break a camel’s back, indicating the camel itself has issues.
Issue one: The index is being "hijacked" by two companies. Samsung Electronics + SK Hynix combined account for nearly 44% of the weight; when they sneeze, the market gets a fever.
This AI bull market is essentially "a one-sided rise in Korean semiconductors," and the more exhilarating the rise, the more violent the stampede.
Issue two: Foreign capital has long been fleeing. From February to March, net sales by foreign investors exceeded 50 trillion won, and BlackRock’s Korea ETF saw a weekly net outflow of $970 million, setting a record, with short positions soaring.
As Middle East tensions escalate and the won falls further, the motivation for foreign investors to cash out only grows stronger.
The label "Sell Korea" has not been torn off despite three crises.
But this is not a replay of 1997 or 2008.
Back then, the script was bank failures, corporate bankruptcies, IMF rescue, and systemic collapse.
Today’s situation resembles more a release of structural vulnerabilities—"rapid rise + concentrated chips + large profit-taking"—leading to a sharp correction in a bull market, not a crisis.
The long-term risk worth monitoring is: discussions about AI wealth distribution have moved from academia into policy circles.
If future institutional expectations form around "re-distribution of excess profits of tech giants," the valuation framework of Samsung and SK Hynix will need to be reconstructed, and that’s what could truly shake beliefs.
Summary: The bull market is not dead, but its structural issues must be addressed.
The old problem of foreign capital fleeing faster than anyone else still persists, and it won’t be fixed overnight.
