Top 5 Key News
1. KOSPI pulls back after first-ever 6,400 breakout
On April 22, the KOSPI breached 6,400 during intraday trading for the first time ever. Following its record closing high of 6,388.47 on April 21 (+169.38p, +2.72%), the market showed mixed movement as foreigners and institutions offloaded stocks to lock in gains, pulling the index back toward the 6,380 range. While Samsung Electronics saw a slight gain, SK Hynix turned lower, though individual buying cushioned the drop.
2. Secondary battery sector surges on rotational buying
During the April 22 pre-market (Nextrade), LG Energy Solution jumped 4.39% by 8:20 AM. As semiconductors like SK Hynix hit a wall and Samsung Electronics dipped 0.91%, secondary battery stocks benefited from strong rotational buying. Experts anticipate this "sector rotation" trend to continue.
3. SK Hynix hits '1.2 Million Won' milestone
On April 21, with strong net buying from foreigners and institutions, SK Hynix saw its share price surpass 1.2 million KRW. This pushed the KOSPI to its record closing high of 6,388.47. Analysts expect the semiconductor-led rally to hold steady for the time being.
4. Warning of 'Semiconductor Illusion'
Despite the KOSPI's record high, about 60% of KOSPI-listed companies have yet to recover to their pre-US-Iran war price levels. Experts warn of a clear divide between semiconductor stocks and domestic sectors like automotive and bio, urging investors to remain cautious of a "semiconductor illusion."
5. KRW/USD rate opens higher at 1,479.5
The exchange rate opened at 1,479.5 KRW, up about 11 KRW, as the second round of US-Iran peace talks stalled, heightening geopolitical uncertainty. The overnight decline in the New York market also pressured the won.
Lead Sectors & Themes
- Semiconductors (AI/HBM): The main driver behind the KOSPI's record run. Faced some adjustment on April 22 due to profit-taking. Mid-to-long-term upward trend remains supported by strong Q1 earnings outlooks.
- Secondary Batteries: Benefited from rotational flow during the semiconductor breather. LG Energy Solution and Samsung SDI are seeing sustained strength.
- Bio/Domestic: Relatively left behind in the rally. K-shaped market polarization is evident, with many companies still struggling to recover to pre-war prices.
Market Movers
Top 3 Gainers
- LG Energy Solution — +4.39% (pre-market) — Beneficiary of battery rotation.
- SK Hynix — Hit record 1.2 million KRW on April 21 — AI/HBM demand persists.
- Samsung Electronics — Slight gain on April 22 — Supported by individual buying.
Top 3 Losers
- SK Hynix — Turned lower in regular session on April 22 due to profit-taking.
- KOSDAQ IT Service Index — -1.00% — Mid-to-small cap IT left behind by large-cap tech.

Global Context
- US-Iran Peace Talks: The second round of talks effectively failed, keeping Middle East tensions high. This caused the New York market to fall, which directly triggered foreign sell-offs and a higher exchange rate in Korea.
- Earnings Expectations: Despite lower US closing prices, the Korean market held up due to bullish expectations for semiconductor earnings and the secondary battery sector.
Checkpoints for Tomorrow

- Foreign Flow in Big Tech: Observe the first 30 minutes of trading to see if foreign investors continue selling or pivot back into SK Hynix and Samsung Electronics.
- Battery Momentum: Track if the rotation into LG Energy Solution and Samsung SDI holds firm.
Investor Action Items
- Monitor Morning Flows: Check by 9:30 AM to see if foreign and institutional selling flips to buying.
- Track Sector Rotation: Monitor the volume and price movement of LG Energy Solution and Samsung SDI immediately after opening.
- Currency Watch: If the KRW/USD hits 1,480, brace for increased foreign selling pressure and evaluate potential impacts on export-heavy large-cap stocks.
