Korean Market Update — 2026-04-25
On April 24, the Korean stock market saw the KOSPI close flat under foreign selling pressure, while the KOSDAQ surged past the 1,200 mark for the first time in 26 years. The main market driver was a sharp rotation of capital out of large-cap semiconductor stocks and into small-to-mid-cap growth shares.
Korean Market Update — 2026-04-25
Market Snapshot
- KOSPI: 6,475.63 (Flat compared to previous day, ±0%)
- KOSDAQ: Closed above 1,200 (Reached a 26-year high, approx. +2%)
- KRW/USD Exchange Rate: Slight fluctuation (Opened at 1,479 range on the previous trading day)
- Market Sentiment: Large-cap KOSPI stocks took a breather, while rotation shifted toward small-to-mid-cap KOSDAQ growth stocks; clear capital shift as foreigners net-sold KOSPI and net-bought KOSDAQ.
Supply & Demand Trends (KOSPI)
- Foreigners: Net-sold KOSPI (massive selling of large-cap semiconductors like Samsung Electronics and SK Hynix); conversely, turned to net-buying in KOSDAQ, driving the 1,200 breakthrough.
- Institutions: Joined the buying spree in KOSDAQ; helped cushion the slight dip in KOSPI.
- Individuals: Net-bought KOSPI; picked up semiconductor stocks at lower prices due to oversold perception, limiting the index's decline.
Top 5 Key News
1. KOSDAQ closes above 1,200 for first time in 26 years
- What happened?: On April 24, the KOSDAQ index touched the 1,200 mark during trading and closed above it, reaching its highest level in roughly 26 years. Joint buying from foreigners and institutions pushed small-to-mid-cap growth stocks like secondary batteries, defense, and biotech higher.
- Market Impact: Broad rally across KOSDAQ sectors; focused gains in secondary batteries and defense themes; accelerated capital flight from KOSPI large-caps.
2. KOSPI flat — Foreigners dump semiconductors
- What happened?: The KOSPI closed virtually flat at 6,475.63. Samsung Electronics and SK Hynix were primary targets for foreign selling, while the decline in the three major New York indices (Nasdaq -2.38%) weighed on investor sentiment. Individual buying helped limit the index's losses.
- Market Impact: Declines in Samsung Electronics and SK Hynix; weakness in the overall KOSPI semiconductor sector; lower-price buying by individuals mitigated the drop.
3. Defense and secondary battery stocks rise — Clear rotation
- What happened?: Amid adjustments in large-cap semiconductors, defense and secondary battery stocks recorded clear gains. While automotive stocks saw weakness, defense-related stocks saw capital inflows due to persistent geopolitical uncertainty. Secondary battery themes in KOSDAQ were bolstered by joint foreign and institutional buying.
- Market Impact: Strength in KOSDAQ defense and secondary battery stocks; relative weakness in automotive and semiconductor large-caps.
4. New York market drops — Nasdaq shock (-2.38%)
- What happened?: On the previous day (23rd), New York indices closed lower: Dow (-1.01%), S&P 500 (-1.74%), and Nasdaq (-2.38%). However, the Philadelphia Semiconductor Index showed strength, sending mixed signals. This influenced the KOSPI, which touched the 6,400 level early on the 24th.
- Market Impact: Downward pressure on KOSPI at the open; concerns of panic among individual investors due to losses in semiconductor inverse ETFs.
5. Individuals betting against semiconductors see losses grow
- What happened?: During the KOSPI semiconductor rally, some individual investors bet on Samsung Electronics and SK Hynix inverse or 3x inverse ETFs, leading to a cumulative loss of -65% this month. Despite Samsung and SK Hynix ranking 1st and 2nd in foreign net selling this month, the index rose, causing losses for those holding "short" positions.
- Market Impact: Mounting losses in semiconductor inverse products; dampened investor sentiment; some shift toward bottom-fishing.
Leading Sectors & Themes
KOSDAQ Secondary Batteries
- Trend: Became the core engine for the KOSDAQ 1,200 breakout due to intense joint buying from foreigners and institutions. Renewed expectations for global electric vehicle adoption.
- Key stocks: General strength in small-to-mid-cap secondary battery stocks.
Defense
- Trend: Inflows continued due to ongoing geopolitical tensions in the Middle East. Defense stocks rose on both KOSPI and KOSDAQ.
- Key stocks: Broad strength across defense-themed KOSDAQ stocks.
Semiconductors (Large-cap weakness)
- Trend: Samsung Electronics and SK Hynix fell under heavy foreign selling. New York market declines and profit-taking pressure converged, leading to a classic rotation pattern into KOSDAQ small-caps.
- Key stocks: Samsung Electronics (down), SK Hynix (down), semiconductor ETFs (weak).
Top Risers & Fallers
Top 3 Risers
- KOSDAQ Secondary Battery Majors — approx. +3–5% — Benefited from joint foreign/institutional buying.
- Defense-related stocks — +2% or more — Driven by Middle East geopolitical tensions.
- KOSDAQ Growth Stocks (Biotech/IT Service) — Gained as funds flowed in from large-caps.
Top 3 Fallers
- Samsung Electronics — Down — Due to heavy foreign net-selling and Nasdaq impact.
- SK Hynix — Down — High foreign profit-taking volume.
- Automotive stocks — Weak — Concerns over a global economic slowdown and capital shift to other sectors.
Global Market Connection
1. New York Market decline (Nasdaq -2.38%) The April 23rd session saw losses across all three major indices. The "risk-off" sentiment due to Middle East tensions created downward pressure on the KOSPI on the 24th. However, the strength of the Philadelphia Semiconductor Index suggests the underlying semiconductor fundamentals remain intact.
2. KRW/USD Exchange Rate pressure The exchange rate opened at 1,479.5 KRW, up 11 KRW from the previous trading day. The persistent strength of the dollar contributed to foreign selling on the KOSPI, as a rising exchange rate decreases the attractiveness of won-denominated assets for foreign investors.
Tomorrow’s Checkpoints
-
Can KOSDAQ hold the 1,200 level?: Need to monitor if it sustains this 26-year high or if short-term profit-taking leads to a correction. Foreign buying continuity is the key.
-
Direction of foreign flow in Samsung and SK Hynix: Keep an eye on whether these heavy-weights see a rebound or continued profit-taking, along with the Philadelphia Semiconductor Index.
-
Exchange rate and US market activity: Watch the 1,480 KRW threshold and whether the Nasdaq rebounds. Keep an eye on geopolitical variables in the Middle East.
Investor Action Items
- Monitor foreign KOSDAQ buying at open: Since the 1,200 breakout was driven by foreign and institutional flow, watch the next open to see if the net-buying trend holds. If they turn to sellers, the risk of a short-term correction increases.
- Catch the reversal signal for Semis: Watch for signs that foreign profit-taking has reached a ceiling and look for the shift toward net-buying. Track the Philadelphia Semiconductor Index and trading volume of semiconductor ETFs.
- Watch for surge in Defense/Secondary Battery volume: Since rotation can be fast, keep an eye on trading volume in these sectors and consider "buying the dip" rather than chasing rallies.
