Seoul shares closed lower on Thursday as investors were disappointed with Micron Technology's earnings results, causing the benchmark Korea Composite Stock Price Index to fall by 0.29 percent. Trade volume was moderate, with losers outnumbering winners, and foreign and retail investors offsetting institutions' sell-off. The local currency gained ground against the US dollar, ending at 1,385.80 won per US dollar. The disappointment in Micron's earnings initially impacted the Kospi, but losses were narrowed as auto and shipbuilding shares performed well. Market bellwether Samsung Electronics saw a modest increase, while Hyundai Motor and shipbuilders experienced gains. However, other big-cap shares like LG Energy Solution, Samsung SDI, LG Chem, Naver, and Kakao suffered declines. This culminated in a market where investors were disappointed with Micron's earnings, but various sectors, such as automobiles, shipbuilding, and biotech, displayed positive performance. The local currency also saw gains against the US dollar.
