Daily Market Strategy: Trading Guide — 2026-06-10
The South Korean stock market saw the KOSPI plunge over 8% on June 8, triggering a circuit breaker amid a global sell-off in tech stocks driven by strong U.S. employment data and fears of Federal Reserve interest rate hikes. With large-scale foreign net selling hitting semiconductor and AI giants, investors should focus on technical rebound potential and shifts in foreign capital flow.
Daily Market Strategy: Trading Guide — 2026-06-10
Market Snapshot
Recent Market Status (as of June 8):
- KOSPI: Fell over 8% to the 7,400-point range (Circuit breaker triggered)
- KOSDAQ: Similar sharp decline (approx. 8%)
- Flow Trends: Large-scale foreign net selling (aligning with global tech stock sell-offs)
- FX/Government Bonds: KRW/USD exchange rate rose (stronger dollar), Treasury yields increased
- Major Decliners: Semiconductor giants such as Samsung Electronics (-10%) and SK Hynix (-10%) suffered the heaviest losses
Global Context — U.S. Market Overview
- Strong U.S. Employment Data: May hiring numbers significantly exceeded expectations, causing the probability of a Federal Reserve (Fed) interest rate hike to soar, which severely dampened sentiment for tech and growth stocks.
- Broad Tech Sell-off: The Nasdaq dropped over 4%, marking its worst performance since April 2025. Semiconductor, AI, and cloud-related stocks faced intense selling pressure.
- Rising Treasury Yields: The sharp rise in the 10-year U.S. Treasury yield intensified concerns over a "high-interest-rate era," with immediate fallout in the Korean market.
Leading Sectors & Themes
Semiconductor & AI Chips (Hardest Hit)
- Movement: The semiconductor sector led the decline during the 8% KOSPI plunge on June 8, hit directly by weakening global AI confidence and Fed rate hike fears.
- Key Stocks: Samsung Electronics (-10%, intraday), SK Hynix (-10%, intraday), and memory-related equipment/material suppliers.
- Checkpoints: Weak guidance from U.S. semiconductor firms soured outlooks for Korean memory chip demand, compounded by heavy foreign net selling. The market is reflecting fears of an overheated AI supercycle.
Tech & IT Services (Wide-ranging Correction)
- Movement: Large-cap IT stocks like Naver and Kakao fell 6–7%, a direct reflection of the Nasdaq's weakness.
- Key Stocks: Naver, Kakao, Samsung SDI, LG Chem, etc.
- Checkpoints: Growth stocks face valuation reassessment pressure due to fears of an interest rate hike cycle. Foreign net selling has expanded into the IT sector.
Defensive & Dividend Stocks (Relatively Resilient)
- Movement: Utilities, power, and telecom stocks saw more limited declines (around 3–4%).
- Key Stocks: Korea Electric Power Corporation (KEPCO), SK Telecom, etc.
- Checkpoints: Defensive demand for stable cash-flow stocks remains intact despite the possibility of rate hikes.
Trading Guide for Key Stocks
This guide is based on brokerage reports and public disclosure data for reference pricing only; investment decisions are the responsibility of the individual.
Samsung Electronics (005930)
- Current Close / Change: Approx. 37,000–39,000 KRW (-10% as of June 8)
- Flow: Increased foreign net selling, institutions also in defensive sell-off mode.
- Fundamental Triggers: Strong U.S. employment → Increased Fed rate hike probability → Worsened memory chip demand forecast. Additionally, weak guidance from global semiconductor firms like Broadcom is interpreted as a signal of intensifying supply competition.
- Target Price / Support/Resistance: Hana Securities recently raised the target price to 430,000 KRW (reference for potential rebounds). Current price (~39,000 KRW) is near the bottom of the 52-week range (approx. 35,000–45,000 KRW).
- Risk Factors: (1) Additional declines if a Fed rate hike is confirmed, (2) Margin deterioration due to global memory chip oversupply.
- Response Scenario: In a favorable scenario (Fed signals delay, Chinese economic stimulus), look for a rebound after observing support at 35,000–37,000 KRW. In an unfavorable scenario (confirming a hawkish Fed), monitor for further potential drops below 33,000 KRW.
SK Hynix (000660)
- Current Close / Change: Approx. 185,000–200,000 KRW (-10% as of June 8)
- Flow: Large-scale foreign net selling (weakening its role as the primary beneficiary of memory chips).
- Fundamental Triggers: Slowdown in HBM (High Bandwidth Memory) demand and poor AI chip guidance. Signals detected of CAPEX delays by customers (NVIDIA, AMD, etc.) due to Fed rate hike concerns.
- Target Price / Support/Resistance: Hana Securities recently set a target price of 2.75 million KRW (relative strength scenario). Current price is mid-range of the 52-week box (approx. 150,000–280,000 KRW). Support at 180,000 KRW, resistance at 220,000 KRW.
- Risk Factors: (1) Prolonged HBM production delays and weak demand, (2) Intensifying price competition with Samsung Electronics.
- Response Scenario: In a positive scenario (strong HBM orders, price stabilization), watch for signals of recovery above 200,000 KRW. In a negative scenario (further decline in memory chip prices), look for downward risk below 170,000 KRW.
Korea Electric Power Corporation (KEPCO, 015760)
- Current Close / Change: Approx. 21,000–22,000 KRW (-3–4% as of June 8, relatively resilient)
- Flow: Defensive demand from institutions and retail; foreign selling remains limited.
- Fundamental Triggers: Government power supply normalization policy and stable dividend yield (approx. 5–6%) make it a key alternative for asset allocation in high-interest environments.
- Target Price / Support/Resistance: 52-week range is 18,000–24,000 KRW. Current price is in the mid-to-upper range. Support at 20,000 KRW, resistance at 23,500 KRW.
- Risk Factors: (1) Prolonged government freezes on electricity rates, (2) Rising fuel costs due to surges in global oil prices.
- Response Scenario: If long-term interest rates continue to rise, its appeal as a dividend play may support the 22,000–23,500 KRW range. Look for an upside break of 24,000 KRW if energy crisis signals emerge.
Upcoming Key Events
- U.S. FOMC Schedule: Essential to verify upcoming Federal Open Market Committee announcements. Fed signals on rate hikes are the critical variable for Korean foreign capital flow.
- South Korea CPI Announcement: Domestic inflation trends influence the Bank of Korea's rate policy, which in turn dictates KRW strength and foreign capital direction.
- Samsung/SK Hynix Earnings Season: Monitor for Q2 earnings release dates. Mentions of memory chip price trends and demand outlooks could spark price rebounds.
- Global Oil & KRW/USD Rate: If KRW weakness and rising oil prices persist, defensive stocks (KEPCO, telcos) are likely to maintain relative strength.
One-Line Strategy Memo
The market is currently in a state of heightened risk-off sentiment. Until the U.S. Fed confirms its interest rate direction, the risk of further corrections for tech and AI-related stocks remains high. Treat the 52-week box bottom (Samsung 35,000 KRW, SK Hynix 170,000 KRW) as your defensive line to seek counter-trend buying opportunities. Meanwhile, maintain exposure to defensive stocks like utilities and telecom companies with high dividend yields, and refrain from aggressive new entries until a rebound signal for global tech (Nasdaq +2% or more) is captured.
