Korean Stocks Surge by Most Since 2008 in Roller Coaster Week

South Korean equities bounced back after their biggest one-day slump on record, as bargain hunters returned to a market battered by panic selling.

The benchmark Kospi surged 9.6%, the biggest gain since October 2008, after sinking by 12% on Wednesday. Samsung Electronics Co. and SK Hynix Inc., the chip heavyweights that paced the country’s world-beating gains since the start of last year, both jumped more than 10%.
