Foreign Money Is Rigging Koreas Stock Market — And It Hits Your 401k [yPfK52rrIhZ]

Foreign money can swing Korea's entire stock market up and down — and it ripples straight into your 401(k). Half the KOSPI is just two stocks (Samsung + SK Hynix). Retail is piled in on record margin debt (₩38 trillion won), 2x leveraged ETFs amplify every move, and the index has tripped its circuit breaker 11 times in history — 5 of them in 2026 alone. When Korea sells off overnight, US chip stocks like Micron and SanDisk drop the next morning. And with AI stocks now ~45% of the S&P 500, that volatility lands in your retirement account.
