Stock Market Strategy: Guidance for Key Stocks — April 27, 2026
On Monday, April 27, 2026, the KOSPI index hit an all-time high, breaking through the 6,600 mark for the first time during intraday trading. The rally, driven by a 5.56% surge in SK Hynix and overall semiconductor momentum, pushed the total market capitalization of South Korean stocks past the historic 6,000 trillion won milestone. Investors should keep a close watch on upcoming US big tech earnings, the status of the Middle East ceasefire, and whether the semiconductor sector has room for further growth.

Global Context — Overnight US Market
- S&P 500 and Nasdaq Hit All-Time Highs on Friday (4/24): Fueled by a semiconductor rally led by Intel and hopes for progress in US-Iran peace talks, both indices rose for four consecutive weeks. The Dow Jones saw its three-week winning streak come to an end.
- Oil Prices Decline: Signs of progress in Iran peace talks pushed oil prices lower, easing energy cost burdens and supporting tech valuations.
- Key Variable This Week: Whether the US-Iran ceasefire holds. Potential for renewed tension following reports of oil tanker seizures over the weekend; Asian markets started the week absorbing these developments.
Leading Sectors & Themes
1st Priority: Semiconductors (HBM & AI Memory)
- Movement: SK Hynix jumped +5.56%, emerging as the 17th largest company by global market cap and acting as the sole engine for the KOSPI.
- Leading Stocks:
- SK Hynix (000660) — +5.56%, highlighted by growth engines like HBM4 and SOCAMM2. Nomura Securities set a target price of 2.34 million won, with multiple brokerages raising targets above 2.1 million won.
- Samsung Electronics (005930) — Rose on expectations of a semiconductor industry recovery; some brokerages (BNK Investment & Securities, as of March) have set a target price of 250,000 won.
- Checkpoints: Confirmation of an earnings surprise for SK Hynix’s Q1 (last week) led to a cascade of target price hikes. Visibility for HBM4 and AI data center demand is confirmed for over 6 months.
2nd Priority: Materials & Secondary Batteries (Leading KOSDAQ 1,200 breakout)
- Movement: The KOSDAQ continues to hold above the 1,200 mark, with strength in materials and secondary batteries.
- Leading Stocks: Buying interest concentrated in large-cap secondary battery material stocks (Ecopro group, POSCO Future M, etc.).
- Checkpoints: Monitor if foreign and institutional inflows continue after the KOSDAQ's historic move above 1,200 last Friday (April 24).
3rd Priority: General Korean Market — Geopolitical Risk Easing
- Movement: Sentiment favoring risk assets has strengthened due to the extended Middle East ceasefire and expectations for US-Iran talks, driving sustained foreign net buying.
- Leading Stocks: General KOSPI large-caps (Samsung Electronics, SK Hynix, etc.).
- Checkpoints: Despite reports of renewed US-Iran tensions over the weekend, the market absorbed the news and opened higher. The sustainability of the ceasefire is the core variable for this week’s mood.

Strategic Memo
Today's KOSPI 6,600 breakthrough and the 6,000 trillion won market cap milestone have reinforced a "risk-on" atmosphere. Maintain positions in semiconductors and AI-related large-caps, but closely monitor the Middle East situation and US big tech earnings. These will dictate whether the current momentum continues or if it triggers profit-taking. Use the 6,400–6,500 range as your primary risk management/support level.
