SkimNews Take
The Kospi's high concentration in a few tech giants, coupled with their vulnerability to internal labor disputes, makes the broader market susceptible to company-specific shocks.

- Kospi closed at 7,493.18, falling more than 6% after briefly breaching the 8,000‑point barrier earlier in the session.
- Samsung Electronics shares dropped 8.6% after its labor union announced an 18‑day strike starting May 21, despite the company’s offer to resume wage talks.
- SK Hynix fell 7.6%, contributing to a broader tech sell‑off that highlighted the index’s concentration, with Samsung and SK Hynix together accounting for a record 42.2% of the Kospi.
- Asian markets tracked the decline, with Japan’s Nikkei down 2%, Hong Kong’s Hang Seng down 1.6%, and China’s CSI 300 down 1.12%, while precious metals also sold off (gold –1.43%, silver –5%).
Why it matters: Investors in Korean tech ETFs lose 6%, while Samsung’s workers face prolonged wage disputes; the market’s heavy reliance on two chips amplifies volatility and pressures other sector stocks.
