 Korea’s Kospi Heads for Record Daily Gain, Defying Efforts to Tame Wild Swings

South Korea’s share market is on track for its biggest daily rise on record, confounding officials’ attempts to limit wild swings in equities and restrain mom-and-pop investors from taking on debt to buy stocks exposed to the global AI boom.

The benchmark Kospi index, dominated by the nation’s largest chip makers Samsung Electronics and SK Hynix, jumped over 17% on Friday in a dramatic reversal of a selloff over the previous three trading days. It means five of the 10 largest single-day moves in the Kospi’s history have occurred since March, while three of the four biggest one-day declines happened in the past five weeks, according to LSEG data.
