Overview
- The KOSPI jumped to multi‑week highs after a sharp semiconductor rally that began Monday following OpenAI’s GPT‑6 Astra release, with Samsung Electronics and SK Hynix logging multi‑percent gains that pushed the index above 7,000.
- Independent industry data showed a strong demand surge: TrendForce reported Q2 DRAM revenue of roughly $154.7 billion and brokers including KB Securities said inventories at Samsung and SK Hynix fell below about 10 days of supply.
- Goldman Sachs’ Asia team has amplified bullish calls, raising a 12‑month KOSPI target to 12,000 and lifting Asia ex‑Japan targets on the view that AI capex and earnings for chipmakers will expand materially.
- Trading flows concentrated the rally in large caps as institutions and foreign investors turned net buyers while retail investors sold, reflecting how Samsung and SK Hynix’s heavy weight can drive index moves.
- Key downside risks are clear and tangible: faster Chinese memory capacity builds, rising oil and inflationary pressure that could alter Federal Reserve policy, and the memory sector’s historical boom‑and‑bust dynamics, all of which could quickly reverse gains and affect downstream buyers facing higher memory prices.
