Top 30 KOSPI Firms Shed 1,035 Trillion Won in H2; Samsung and SK Hynix Account for 90%

Korean media reported that the top 30 KOSPI companies by market cap lost about 1,035 trillion won in the second half, with Samsung Electronics and SK Hynix alone accounting for roughly 90%. This highlights a sharp correction in memory chip stocks after a strong rally and elevated market concentration risk. For SK Hynix, short-term volatility may increase, but the news does not change fundamentals, so the impact is neutral.
