South Korea's Kospi index opened sharply lower on Thursday, trading nearly 3 percent below its previous close by late morning.
The decline was driven by an overnight selloff in US semiconductor stocks, which weighed heavily on Korean chipmakers and broader technology holdings.
The market move marks a continuation of the severe correction that began earlier in the week.
On Tuesday, the Kospi crashed nearly 10 percent, triggering circuit breakers as aggressive profit-taking engulfed the technology sector.
The benchmark had been trading near record levels before the reversal, making the recent volatility one of the sharpest drawdowns in recent memory.
Investors are now grappling with the pace of the unwind.
