South Korea's Kospi surges 6% as chip stocks rebound. Here are two major triggers

South Korea’s KOSPI surged as much as 6% to an intraday high of 8,982, extending gains for a second straight session and recovering sharply from earlier losses. Trading was briefly halted after a 5% jump triggered a sidecar mechanism. The rally follows a steep 10% drop earlier in the week driven by a selloff in domestic chip stocks.
