Today's Stock Strategy: Key Holdings Action Guide — May 5, 2026
On Tuesday, May 4, 2026, KOSPI surged 5.12% to an all-time closing high of 6,936.99, driven by a semiconductor rally led by SK Hynix breaching a 1 trillion won market capitalization. Meanwhile, the U.S. market (May 4) fell as crude oil spiked 6% following Iran's intensified blockade of the Strait of Hormuz, elevating geopolitical risk as a key investor focal point. As markets reopen May 6, investors should watch for further Middle East developments, sustained semiconductor supply momentum, and profit-taking pressure on SK Hynix near its peak.
Today's Stock Strategy: Key Holdings Action Guide — May 5, 2026
Today's Market Snapshot
- KOSPI: 6,936.99 (+5.12%, +~338pt)
- KOSDAQ: Climbed in tandem; confirm closing data separately
- Supply/Demand Trends: Foreigners led massive net buying (semiconductor sector concentrated), institutions joined with net purchases

- Trading Volume: Record-high KOSPI day; estimate heavy turnover
Global Backdrop — U.S. Market Overnight
- New York Market (May 4 Close): S&P 500 and Dow finished lower. Iran executed military aggression—attacking multiple vessels in the Strait of Hormuz and triggering fire at UAE oil ports—spreading risk-off sentiment. One Korean vessel was reportedly hit.
- Oil Surge: WTI crude jumped 6%. Iran's confirmed grip on the strait rattled energy supply concerns across markets. Russell 2000 and small caps deepened losses.
- Core Headline: Iran's Hormuz blockade tightened—UAE missile interception and allied nations on high alert. Trump administration orders to prepare Iran infrastructure strikes fueled the fire.
Leading Sectors & Themes
Tier 1: Semiconductors / AI Memory
- Movement: The core engine of KOSPI's 5.12% jump. SK Hynix rallied +12%+; Samsung Electronics showed strength too.
- Key Movers:
- SK Hynix (000660) — +12%↑ today; market cap broke through 1 trillion won. Samsung + SK combined exceed 3 trillion won.
- SK Square (402340) — +10.70%. Reflects rising stake value in SK Hynix subsidiary.
- Samsung Electronics (005930) — Joined gains. Semiconductor supercycle narrative intact.
- Check Point: Nomura Securities raised SK Hynix price target from 1.93 million won to 2.34 million won (among Korea and overseas houses, the highest). Expectations for Q2+ HBM and AI memory supply deals underpin the supply explosion.

- Key Movers: S-OIL, GS Caltex and major refiner plays expected to benefit (verify specific daily moves directly).
- Check Point: WTI spike fuels inflation concerns market-wide but delivers near-term tailwind to refiners. Prolonged Middle East crisis risks headwinds for aviation and logistics.
Tier 3: Defense / Security
- Movement: Iran-U.S. friction inflames Middle East instability, sparking global defense demand expectations. Hanwha Aerospace, LIG Nex1 et al. in focus.
- Key Movers: Hanwha Aerospace, LIG Nex1, Hyundai Rotem and major defense names (verify daily moves directly).
- Check Point: Despite U.S. market losses, geopolitical risk becomes fuel for defense stocks. As Middle East escalation scenarios materialize, defense upside accelerates.

SK Hynix (000660)
- Today's Close / Change: ~+12%↑ (confirm exact close—opened +4%, extended gains thereafter)
- Supply/Demand: Foreigners massive net buyers; institutions joined

- Risk Factors: ①Middle East geopolitical risk cools global demand sentiment → foreigners liquidate profits / ②Valuation strain at high ground—post–1 trillion won overheating risk

Samsung Electronics (005930)
- Today's Close / Change: Joined strength during KOSPI record day (verify exact figures via HTS)
- Supply/Demand: Foreigner and institutional interest aligned
- Fundamental Trigger: BNK Investment Securities et al. raised price target to 250,000 won citing improved semiconductor outlook and strengthened competitive position (March baseline). Samsung + SK combined 3 trillion won market cap milestone symbolic.

- Action Scenarios: Bullish — supercycle narrative sustains; Samsung trails SK Hynix higher toward BNK's 250K target / Bearish — foreigner selling flip; monitor support level break
SK Square (402340)
- Today's Close / Change: +10.70% (SK Hynix 1 trillion won market cap windfall)
- Supply/Demand: SK Hynix buying spills over; foreigners and institutions engaged
- Fundamental Trigger: SK Hynix stake value directly flows to SK Square NAV (net asset value). SK Hynix 1 trillion won milestone pushes SK Square's holding value higher.
- Broker Targets / Support & Resistance: Recent 52-week highs/lows—recommend HTS check (Korean media reports show SK Square targets tracking upward alongside SK Hynix upgrades).
- Risk Factors: ①SK Hynix share correction compresses SK Square NAV / ②Holding company structure ties performance to stake value more than direct business fundamentals
- Action Scenarios: Bullish — SK Hynix strength persists; SK Square upside remains; watch NAV discount narrow / Bearish — SK Hynix profit-taking ripples through; +10.70% jump today invites near-term trimming pressure
Must-Watch Events Tomorrow
- May 5 (Children's Day) — Korean Markets Closed: Domestic exchange shuts. Prepare for May 6 reopening.
- Middle East Monitoring (Ongoing): Iran's Strait of Hormuz actions + U.S. military/diplomatic response. UAE, Bahrain ally moves. WTI direction determines May 6 gap bias.
- U.S. FOMC Commentary (Ongoing): Fed Chair Powell and colleagues' scheduled remarks—rate-hold reconfirmation stabilizes risk appetite.
- SK Hynix Nomura 2.34M Won Target — Proximity Check: Measure current price vs. 2.34M target. Additional broker upgrades shape May 6 gap direction.
One-Line Strategy Note
KOSPI hit an all-time 6,936 on May 4 led by SK Hynix, but the U.S. market closed lower as Iran pushed crude 6% higher. May 6 reopening pivots on geopolitical de-escalation—if Iran tensions ease, maintain semiconductor overweight (SK Hynix, Samsung), otherwise hedge into defense and energy plays. SK Hynix: watch Nomura 2.34M won target arrival and foreigner supply flows as your trailing-stop line; brace for profit-taking.
