U.S. and Korean tech stocks are now tightly linked — and that could be a worry for investors
📰 source: cnbc_topnews · 💼 business
the 60-day correlation between the kospi and nasdaq 100 hit 0.50, highest since 2021, driven by ai spending linking us tech giants and korean memory chipmakers. samsung and sk hynix now account for over half of the kospi index, making it essentially a semiconductor index.
this gives asian investors an early read on the global ai trade before wall street opens. on july 13, the kospi fell more than 8% after sk hynix plunged 15%, and the nasdaq 100 dropped 1.88% later that day. samsung reports earnings about two weeks before us chipmakers, providing early signals.
the rising correlation erodes diversification benefits. analysts warn that a slowdown in hyperscaler capex would hit korea harder than most markets, and china's expansion into memory chips adds another risk.
why it matters: rising correlation between us and korean tech stocks reduces diversification benefits, exposing investors to concentrated ai hardware risk.
