SK Hynix briefly hit the limit-down in pre-market trading on South Korea’s
alternative trading platform NEXTRADE (NXT) after an 11-share trade at 1,168,000
KRW around 08:00 local time, a 29.97% drop versus the prior close. Trading later
resumed and the decline quickly narrowed to about 3–4%. NXT says it will
introduce a static volatility interruption (VI) next month to block orders that
deviate sharply from the previous close from executing immediately.
