Hyosung Heavy Industries shares, once dubbed a "king stock" as they approached 5 million won, have fallen more than 60% in six months to the 1.6 million-won range, outpacing declines among large semiconductor stocks. The shares closed at 1.612 million won on Nov. 6, down 9.99% from the previous session and sharply below the one-year high of 4.742 million won. Third-quarter consolidated operating profit rose 10.8% year over year to 243.5 billion won, but remained below the 306.5 billion won consensus estimate as logistics disruptions and higher costs pressured earnings. Brokerages cut their target prices from the 4 million-won range to the 3 million-won range, citing uncertainty over U.S. trade policy and weaker peer valuations. The office and technical workers' union said it would begin a two-week full strike from Nov. 17 unless management offers an acceptable package, following a 72-hour warning strike from Nov. 4 to Nov. 6. The union is seeking a 10% base-pay increase, a performance-bonus framework and narrower welfare differences between job categories. It said employees had not been adequately rewarded despite consolidated operating profit rising 106% last year to 747 billion won.
