Hyein rose 8.8% to 10,630 won by 9:08 a.m. on September 4, after briefly gaining more than 10%, extending a rebound from a nearly 27% decline over the previous three sessions. The stock had fallen 2.29% on August 31, 13.08% on September 1 and 11.61% on September 2, as traders questioned whether a namesake political theme had ended after Basic Income Party Rep. Yong Hye-in was nominated as Minister of Gender Equality and Family. Hyein closed at 9,750 won on September 3, up 2.63%. The company, which traces its origins to Hyein Trading Company in 1960, supplies construction-equipment parts, power generators, engines and maintenance services. It has no reported business, equity, personnel or other direct relationship with Yong. The stock had gained roughly 195% from early August through August 28, the strongest performance among KOSPI-listed companies during that period, before profit-taking and supply-demand pressures triggered a correction. An earlier record identified the company as Hyundai Elevator; the updated account identifies the shares as Hyein.
