1. Semiconductors

Samsung Electronics reported preliminary third-quarter results on the 8th, posting revenue of 195 trillion won and operating profit of 107.4 trillion won — a year-on-year surge of 782.5%. Rival SK Hynix came under modest selling pressure on the 6th, trading around 1.8 million won intraday, though analysts remain broadly optimistic: market estimates put SK Hynix's third-quarter operating profit at roughly 7.7 trillion won, rising to approximately 8.6 trillion won in the fourth quarter, underpinned by expectations of improving margins on high-bandwidth memory (HBM) chips.

2. Components

Samsung Electro-Mechanics disclosed on the 6th that it had signed a multilayer ceramic capacitor (MLCC) supply agreement worth approximately 290 billion won with a large global technology firm, covering deliveries in 2027. The deal is the company's sixth long-term supply contract of the year; the cumulative value of agreements signed since May now stands at roughly 3.9 trillion won, reflecting sustained demand for AI server components.

3. Shipbuilding

HD Hyundai Heavy Industries failed to reach a labour settlement before the Chuseok holiday after union members voted down a provisional wage agreement on the 2nd; no further bargaining dates have since been scheduled. At Hanwha Ocean, wage talks with the main union continue, while six members of a subcontractors' union have staged a high-altitude sit-in, occupying a crane and a rooftop in protest. The three major South Korean shipbuilders — HD Hyundai Heavy Industries, Hanwha Ocean, and Samsung Heavy Industries — have collectively secured orders worth $38.8 billion (roughly 52 trillion won) so far this year, with Samsung Heavy Industries reaching 89% of its annual target. Nevertheless, the competitive picture remains challenging: South Korea's share of global new orders in the first nine months of the year was just 14%, against China's 80%.

4. K-pop

Shares in HYBE, the entertainment group behind BTS and a stable of other acts, rose as much as 5.6% intraday on the 7th to 165,800 won. The catalyst was a combination of chart success — girl group Katseye reached number one on the Billboard 200 — and bullish concert projections. Analysts at Hana Securities estimate that a planned BTS stadium tour of 24 dates across North America and Europe, along with other live events, could draw a total audience of approximately three million.

5. Capital Markets

South Korea's benchmark KOSPI index fell sharply on the 8th, closing down 177.97 points, or 2.62%, at 6,625.93. Foreign investors were net sellers of 2.02 trillion won worth of shares, joined by institutional investors who offloaded a net 1.30 trillion won; retail investors absorbed the bulk of the selling, buying a net 2.55 trillion won. Among blue-chips, Samsung Electronics fell 2.42% and SK Hynix dropped 2.44%. The tech-heavy KOSDAQ index also declined, shedding 0.69% to close at 892.27.
