Korea’s stock market is down another 6% as I write tonight.
If you own U.S. tech stocks, this matters even if you’ve never owned a Korean share.
Samsung and SK Hynix are major memory-chip suppliers, and their earlier declines put pressure on a crucial part of the same semiconductor trade many U.S. portfolios depend on.
Owning Micron, Nvidia, and a technology ETF can look like three different positions. But those holdings can share exposure to expectations for AI spending and semiconductor growth. When investors start marking down one part of that trade, I want to check how much risk is tied to the same assumptions elsewhere in the portfolio.
Today’s U.S. semiconductor selloff makes that question more urgent. Below, I’ll walk through the damage, the U.S. tech leaders still holding up, and the signs I’m watching to decide whether this pressure is spreading or an opportunity is starting to develop.
