KOSPI 8,000 — Historic Level Reached as Semiconductor Rally Drives Index
The KOSPI's crossing of 8,000 is the headline event — a milestone driven almost entirely by Samsung Electronics and SK Hynix, whose combined market cap now equals approximately half the entire index. This concentration is both the KOSPI's strength (if semis continue their HBM-led cycle) and its vulnerability (any Samsung or Hynix earnings miss carries systemic index impact). Foreign investors reportedly braked their net selling sharply at 8,000 — interpreting the level as a buying opportunity rather than a resistance ceiling. For KOSPI bulls, DRAM and HBM pricing data in the coming weeks is the litmus test.
