Korea Market Update: 2026-04-27 긴급 브리핑
As the KOSPI pauses after reaching record highs, this week (April 27–May 1) is defined by the upcoming US FOMC meeting and major Big Tech earnings. Last week, foreign investors offloaded nearly ₩1.8 trillion in profit-taking, and retail investors hit a near-record monthly net sell-off of ₩14 trillion. Meanwhile, semiconductors, component/equipment stocks, and biotech have pushed the KOSDAQ above the 1,200 level for the first time in about 25 years.

Top 5 News
1. KOSPI takes a breather; 'Super Week' ahead with FOMC and Big Tech
- What happened?: After hitting record highs for three consecutive days, the KOSPI closed slightly lower at 6,470 on April 24. This week (April 27–May 1) is a 'Super Week' with the US FOMC interest rate decision, central bank meetings in Japan and Europe, and major Big Tech earnings, signaling increased volatility. NH Investment & Securities suggests that the Federal Reserve's response to rising global oil prices is the biggest variable for global markets.
- Market Impact: Potential for short-term KOSPI fluctuations; the key is whether foreigners continue to sell or return. Expect risk appetite to return if rates are held steady.
2. Foreigners offload ₩1.8T near peak; Samsung and SK Hynix targeted
- What happened?: As the KOSPI breached 6,500 for the first time last week, foreign investors net sold nearly ₩1.8 trillion, focusing selling pressure on Samsung Electronics and SK Hynix to lock in gains at the peak.
- Market Impact: Downward pressure on short-term stock prices for Samsung and SK Hynix, as the market digests the rally in semiconductor large-caps.

3. Retail investors hit ₩14T in monthly net sales—nearing record
- What happened?: As the KOSPI pushed past 6,500, retail investors offloaded a record-shaping ₩14 trillion. Retailers betting on 3x inverse semiconductor ETFs suffered losses of around -65%, and they were the top net sellers of Samsung Electronics and SK Hynix this month, leading to "mismatched" investment losses.
- Market Impact: Retail losses from inverse bets have been compounded by the semiconductor rally; their potential re-entry remains a supply-demand variable.
4. KOSDAQ crosses 1,200, led by semiconductors and biotech
- What happened?: The KOSDAQ hit a 25-year high, breaking 1,200 on April 24. The rally was driven by semiconductor component/equipment and biotech stocks, with funds rotating into small-to-mid-cap growth stocks amid foreign and institutional buying.
- Market Impact: Potential for sustained strength in KOSDAQ tech and biotech; watch for rotation between KOSPI and KOSDAQ.

5. Philly Semiconductor Index tops 10,000 for the first time
- What happened?: The Philadelphia Semiconductor Index hit 10,000 points, boosting global optimism. Despite volatility from geopolitical tensions in Iran, the domestic market has shown a pattern of quick "V-shaped" recoveries. The market is now focused on which sector will lead after semiconductors.
- Market Impact: Accelerated rotation into components, biotech, and defense as semiconductors hit peak valuation levels.
Leading Sectors & Themes
- Semiconductors: Large-caps (Samsung, SK Hynix) seeing slight adjustments due to foreign selling, while small/mid-cap component/equipment firms remain strong.
- Biotech/Healthcare: Core driver of the KOSDAQ 1,200 rally; strong foreign and institutional interest as valuation re-rating continues.
- KOSDAQ Growth Stocks: Benefiting from rotation; KOSDAQ sectors like Electrical/Electronics (+2.92%) and Machinery/Equipment (+4.44%) saw strong inflows.
Top Movers (April 24 Close)
- Gainers: KOSDAQ Machinery/Equipment (+4.44%), Electrical/Electronics (+2.92%), General Services (+2.13%).
- Losers: Samsung Electronics (Foreign selling pressure), SK Hynix (Large-cap reduction), 3x Inverse Semiconductor ETFs (-65% monthly).
Global Links
