KORU is trading at $10.76, up +5.59% in pre-market, rebounding sharply after falling 14.66% on October 22. - The broader Korean-market backdrop remained weak: the KOSPI opened October 23 down 2.36%, as concerns about AI spending and overnight U.S. technology losses weighed on chip stocks. - Rising oil prices added to market jitters. These factors explain sector pressure but do not establish the cause of KORU’s opposite-direction pre-market move.
