Iran Fears Crushed Korean Chip Stocks. Here's 1 Thing American Memory Investors Should Watch.
2026-03-13 10:15:00 ET
In the wake of the first airstrikes on Iran last week, South Korea's stock market melted down. The Korea Stock Exchange Composite index (KOSPI) -- which tracks all the stocks traded on South Korea's Korea Stock Exchange -- plunged more than 18% over just two days, its worst weekly performance since 2008.
The drop was largely due to double-digit declines in the share prices of the top global providers of memory chips -- tech behemoth Samsung Electronics and memory chipmaker SK Hynix. Together, these two stocks collectively account for more than 33% of the KOSPI.
Could the same thing happen to U.S. chipmakers, like memory-chip maker Micron Technology (NASDAQ: MU) or semiconductor behemoth Nvidia (NASDAQ: NVDA) ? It's unlikely.
