Ask what Korea is talking about.

The tech-heavy Nasdaq fell more than 2 percent on Thursday as growth stocks weakened after earnings from Tesla and Meta did little to address AI-related concerns, with rising oil prices adding to the pressure, the Korea Times reports. The S&P 500 also dropped, and AI-linked stocks dragged markets down worldwide, with oil hitting its highest levels since May on worries about the war with Iran. Korean shares opened sharply lower Friday, down 2.36 percent at the open, weighed down by overnight losses in U.S. AI and semiconductor stocks and rising oil prices, according to the Korea Times.
