2 min readSource

KOSPI hits a fresh record high of 4,552.37 on Jan 8, 2026, as defense and shipbuilding gains offset profit-taking in tech stocks like Samsung Electronics.

The engines of heavy industry didn't stall even as tech giants took a breather. According to Yonhap, Seoul's benchmark KOSPI clinched its fifth consecutive record-breaking session on January 8, 2026, overcoming a wave of profit-taking in the semiconductor sector.

Defense and Shipbuilding Surge as Tech Giants Slide

Defense and shipbuilding stocks were the day's clear winners. Industry leader Hanwha Aerospace soared 7.92% to 1.09 million won, while HD Hyundai Heavy Industries jumped 4.49%. In contrast, Samsung Electronics fell 1.56% to 138,800 won, despite projecting a record 20 trillion won operating profit for the fourth quarter. It's a classic case of 'sell on news' as investors lock in gains from the AI-driven tech rally.
