South Korea's stock market crashes, trading halted for 20 mins

South Korea's benchmark KOSPI fell as much as 8.2% on Friday, erasing gains from the previous session and triggering a 20-minute circuit-breaker halt. Shares of Samsung Electronics and SK Hynix plunged more than 9% each, while foreign investors offloaded Kospi stocks worth $1.7 billion in early trade. The crash was heavily driven by a massive drop in US technology shares.
