SEOUL: Round-up of South Korean financial markets:

South Korean shares ended lower on Wednesday, as heavyweight Samsung Electronics fell on a Reuters report that its high-end chips were yet to fully pass Nvidia’s test for use, while broader market focus was on second-quarter earnings.

The benchmark KOSPI closed down 15.58 points, or 0.56%, at 2,758.71.

Chipmaker Samsung Electronics fell 2.26%, after Reuters reported that its fourth-generation high bandwidth memory or HBM3 chips had been cleared by Nvidia for use in its processors, but fifth-generation HBM3E chips were yet to meet the U.S. chipmaker’s standards.

Rival SK Hynix, which already supplies high-end chips to Nvidia, rose 1.71%.

“There will be major exporting companies’ second-quarter earnings in the domestic market tomorrow, from SK Hynix to LG Energy Solution and Kia,” said Lee Kyoung-min, an analyst at Daishin Securities.

South Korea’s consumer sentiment in July was the most optimistic in 27 months, with a brighter spending outlook due to easing inflation concerns, a survey showed.
