Market-Moving Issues (at least 3)

Institutional Buying Lifts KOSPI Back to 6200—Semiconductor Earnings Outlook Leads

• What happened: On April 20, KOSPI closed higher and recaptured the 6200 level despite Middle East geopolitical uncertainty, driven by institutional buying. First-quarter earnings expectations centered on semiconductors outweighed geopolitical risks. The previous day (17th) saw the index close at 6191.92 after suffering a 2 trillion won foreign selling wave, but recovered within a day.
• Market impact: While foreign investors maintained selling pressure, institutions took on a defensive role and spearheaded the index rebound. Near-term resistance remains, but earnings expectations keep the upside open.
• Related stocks: Samsung Electronics, SK Hynix (large-cap semiconductor focus)

KOSDAQ Extends 6-Day Rally, Retrying 1200 Breakthrough

• What happened: Amid Middle East conflict resolution hopes, KOSDAQ extended its 6-day winning streak and is making another attempt to break through the 1200 level. The government is pushing institutional regulatory reforms to boost institutional fund inflows, while investors who lagged on KOSPI's rally are flowing into KOSDAQ.
• Market impact: KOSDAQ, which had been relatively sidelined versus KOSPI, is gaining traction through belated catch-up buying. Government institutional fund inflow reforms are also fueling expectations for a favorable environment for small and mid-cap stocks.
• Related stocks: KOSDAQ biotech and small-cap growth stocks broadly

투심 살아난 코스닥 6거래일 랠리…1200 넘어설까 | 서울경제

Hyundai Motor, Samsung, SK Hynix Unions Demand Record Performance Bonuses

• What happened: Hyundai Motor union demanded performance bonuses equivalent to 30% of net profit. Following SK Hynix union (10% of operating profit) and Samsung Electronics union (15% of operating profit), the competition for large-cap performance bonuses has intensified. Labor negotiations backed by record-breaking earnings have emerged as a major issue.
• Market impact: Growing attention to how increased labor costs will impact corporate cost structures. Samsung Electronics, SK Hynix, and Hyundai Motor could all face near-term uncertainty from labor negotiations.
• Related stocks: Hyundai Motor (005380), Samsung Electronics (005930), SK Hynix (000660)

Major Corporate Disclosures & Earnings (at least 3)

Telecom Big Three—Q1 Earnings Outlook Mixed (SKT & KT Slowing, LGU+ Growing)

• Details: First-quarter earnings for South Korea's three mobile carriers are expected to diverge. SK Telecom and KT are seen facing profitability headwinds from the hacking incident aftermath, while LG Uplus is expected to maintain growth momentum.
• Stock reaction: Telecom stocks show mixed dynamics balancing dividend appeal with earnings expectations, creating stock-by-stock differentiation
• Investor takeaway: For SKT and KT, follow-up costs from the hacking incident and customer churn will be key factors. LGU+ offers relative upside potential worth watching. Ahead of earnings season proper, selective position adjustments are warranted.

Samsung Electronics & SK Hynix—Record Earnings Drive Brokerage Target Price Hikes

• Details: Samsung Electronics posted record first-quarter operating profit of 57 trillion won, far exceeding market expectations. SK Hynix is also projected to deliver first-quarter operating profit exceeding that of Microsoft and Google. Brokerages are rolling out target prices of "2 million per share for Hynix, 400,000 won for Samsung."
• Stock reaction: Both trading near all-time highs with volatility. Short-term profit-taking selling faces off against further upside hopes
• Investor takeaway: Goldman Sachs analysis suggests memory industry remains in an uptrend but may weaken from H2 2026 onward. Interpretations of LTA (long-term supply agreements) diverge between "risk signal" and "structural change." Both stocks can maintain a "buy" stance but require caution on H2 industry trajectory shifts.

Samsung, Hyundai Motor, LG—Economic Delegation Departs for 'Global South' Push

• Details: Samsung Electronics Vice Chairman Lee Jae-yong, Hyundai Motor Group Chairman Chung Euisun, and LG Group Chairman Koo Kwang-mo joined economic missions to India and Vietnam, accelerating Korean conglomerates' "Global South" market push. Korea's major firms are reducing China and US dependency while diversifying into emerging markets.
• Stock reaction: Mid-to-long-term growth momentum expected to strengthen. Day-of impact secondary to longer-term momentum factor
• Investor takeaway: Worth monitoring whether Global South expansion becomes a medium-to-long-term valuation re-rating driver for Samsung, Hyundai Motor, and LG amid prolonged US-China tensions.

Macro Economy & Policy Factors

① Middle East Geopolitical Risk: Uncertainty Persists vs. De-escalation Hopes Mixed

Middle East conflict de-escalation hopes have periodically driven market rebounds, though uncertainty remained unresolved as of April 20. The market appears to have built some immunity to geopolitical risk, with semiconductor earnings expectations now dominating the picture. In the bond market, foreign investors bulk-purchased government bond futures (3-year and 10-year) in a pattern suggesting early pricing of Middle East uncertainty followed by rebound moves.

② Foreign Investor Flows: Record March Net Selling Followed by Gradual April Return Signs

In March, foreign investors dumped 43.5 trillion won from domestic stocks, marking three consecutive months of net selling. However, per Reuters reporting, Middle East stability hopes, strong AI memory demand, and Seoul corporate governance reforms are converging to show signs of gradual foreign fund return in April. Expectations of foreign investor net buying reversal are rising in both equities and bonds.

How Foreign Press Views Korea's Market

① Reuters (April 17, 2026): "After Brutal March, Korean Capital Markets Are Luring Foreign Investors Back"

Reuters reported that Korea's capital markets are attracting renewed foreign buying flows following March's massive selloff. Three compound drivers—① Middle East stability hopes, ② Hot AI memory trade, ③ Seoul's corporate governance reforms—are fueling concurrent gains in both stocks and bonds, the analysis showed.

② Reuters (March 26, 2026, contextual background): "Iran War Fear Made Korean Stocks Cheaper, Not Weaker"

Despite March's war scare selloff, KOSPI's 12-month forward PER actually declined 28% (valuation improvement). This meant corporate earnings growth outpaced share price declines, reinforcing long-term Korean stock appeal.

Watch Points Going Forward

• Scheduled events:
  • SK Hynix Q1 earnings release (watch for market expectations beat)
  • Telecom Big Three (SKT, KT, LGU+) Q1 earnings expected—hacking aftermath impact and LGU+ growth trajectory confirmation
• Economic indicators & schedule:
  • Kevin Warsh Federal Reserve nominee Senate confirmation hearing (this week, Korea time)
  • US Q1 GDP release (watch for growth slowdown signals)
  • US March Producer Price Index (PPI) release
  • WGBI (World Government Bond Index) fund inflow momentum tracking
• Technical & supply-demand watch points:
  • KOSPI 6200 support hold—institutional net buying continuity key
  • KOSDAQ 1200 breakthrough potential momentum—could trigger momentum stock catch-up buying wave if cleared
  • Foreign investor net buying conversion watch—additional Middle East easing could refocus attention on semiconductor large-caps

Investor Checklist

• Semiconductor weight review: Post-Samsung Q1 surprise, reassess semiconductor (Samsung Electronics, SK Hynix) positioning weighing short-term profit-taking versus Goldman Sachs' warned H2 2026 industry slowdown
• KOSDAQ catch-up buying caution: KOSDAQ's 6-day rally carries near-term overheating risk at 1200 breakthrough—prefer holding existing positions or staged exit over fresh entries
• Telecom earnings season response: SKT and KT face hacking fallout; LGU+ benefits relatively—prepare for volatility swings around earnings with diversified positioning
• Global macro event prep: Major US events cluster this week (GDP, PPI, Warsh hearing)—dollar strength resurgence risks foreign fund outflows; recommend keeping some cash reserves
