Global Morning Briefing — 2026-06-03

Market Snapshot at a Glance

U.S. Market Closing Review

U.S. stocks saw all three major indices hit record highs on Tuesday, June 2. The S&P 500 crossed the 7,600 mark for the first time, while the Dow Jones Industrial Average rose +0.4% and the Nasdaq Composite added over +0.1%.

AI chip mania takes the lead: Marvell Technology (MRVL) saw a massive rally after NVIDIA CEO Jensen Huang remarked that "Marvell could become the next trillion-dollar company." Hewlett Packard Enterprise (HPE) also climbed steeply, fueled by a brighter outlook for AI chip demand. The tech sector remained robust, with AI-related hardware companies grabbing the spotlight.

Volume and sector rotation: While tech led the charge, small-cap stocks (Russell 2000) and non-tech sectors also showed strong relative returns amid the Nasdaq's mild movement. The cooling of geopolitical risks encouraged broader buying, with consumer staples like P&G and the healthcare sector showing positive responses.

Closing atmosphere: The market reacted positively to news of progress in U.S.-Iran peace negotiations, and falling oil prices helped calm inflation concerns. Investors continued to support the tech rally, even amidst questions about AI profitability.

Key Stocks (as of June 2)

Top Gainers

• MRVL (Marvell Technology) — Historic surge: NVIDIA CEO Jensen Huang’s assessment of Marvell as "the next trillion-dollar company" caught the market's attention, suggesting its data center chip solutions are becoming pivotal in the AI infrastructure stack.

• HPE (Hewlett Packard Enterprise) — High growth: Driven by increased AI chip demand and deeper investment in enterprise solutions, becoming a key beneficiary of the early June rally.

• NVDA (NVIDIA) — Sustained uptrend: NVIDIA maintained its market leadership as the peak season for AI chip demand continues.

Top Decliners

• GOOGL (Alphabet) — Down about 1%: Experienced a technical correction following the announcement of a large-scale share buyback program. However, it did not significantly impact the overall market rally.

Macro & Economic Indicators

• 10-Year U.S. Treasury Yield: Hovering in the 4.8-4.9% range. While it rose recently due to inflation fears, the cooling of geopolitical risks from U.S.-Iran peace talk progress has helped stabilize it.

• U.S.-Iran Peace Talks: Reports that both nations agreed to extend a truce and begin negotiations in early June lowered oil prices and improved sentiment, easing concerns over the price spikes seen during the May skirmishes.

• Dollar Index (DXY): Flat trajectory. Gains for the dollar were limited as investors showed a preference for risk assets amid growing global stability.

Global Top News

Intense competition for AI chip solutions

• What happened: NVIDIA’s CEO pointing to Marvell as a "trillion-dollar company" signaled that NVIDIA’s monopoly in the AI chip ecosystem might face competition. Meanwhile, enterprise infrastructure firms like HPE are rising on increased AI solution demand.
• Market implications: Likely positive for the Asian semiconductor industry (Samsung, SK Hynix, TSMC). Korea’s semiconductor and secondary battery sectors are well-positioned as supply chain partners.

U.S.-Iran peace talk progress eases global risks

• What happened: With the U.S. and Iran agreeing to extend a truce in early June, geopolitical risks in the Middle East have significantly receded. Oil prices fell, calming inflation fears.
• Market implications: Lower oil prices reduce import costs for the Korean economy, potentially boosting the profitability of energy-intensive industries (steel, chemicals, refining).

China intervenes in global oil stability

• What happened: Reports suggest the Chinese government is stabilizing global oil price volatility through strict supply management and price guidance, balancing economic growth with energy security.
• Market implications: Helps ease energy import cost pressures across Asia and improves the outlook for Korea’s exports to China.

Global volume recovery

• What happened: A broad rally is underway as the S&P 500 hits record highs, with gains spreading from tech to non-tech and small-cap stocks.
• Market implications: Improved global sentiment may increase demand for emerging market assets (including Korea), potentially creating room for KOSPI and KOSDAQ to rise further.

Korean Market Checkpoints

The U.S. AI chip rally and the progress in U.S.-Iran peace talks provide a dual positive signal for Korea. First, increased global AI investment likely benefits Samsung Electronics and SK Hynix. Second, lower oil prices and eased geopolitical risks could lead to a stronger won and improved export competitiveness. Third, global sentiment suggests room for the KOSPI and tech-heavy KOSDAQ to continue rising. Keep a close eye on volatility in Korean interest rates and the dollar.

Watch List

• Economic Indicators/Events: June PMI for Korea (manufacturing/services), U.S. employment data (first week of June).
• Earnings Releases: Conclusion of the current cycle for Big Tech (Microsoft, Tesla, etc.).
• Fed/Policy Events: Keep an eye on Fed Chair Powell’s remarks for signals on interest rates.
• Risk Factors: Potential oil price spikes if U.S.-Iran talks collapse; potential correction due to tech valuation overheating.

Investor Action Items

1. Morning Session: Focus on the momentum of AI chip beneficiaries like Marvell and HPE and how it might lift Korean tech stocks; check supply chain benefit scenarios for Samsung Electronics and SK Hynix.
2. Sectors/Stocks to Watch: (1) Semiconductor/AI supply chain: Samsung Electronics (005930), SK Hynix (000660), NCSoft (036570); (2) Energy efficiency: Hanwha Q Cells (121600), GS Energy (078930).
3. Risk Management: Valuation concerns for global tech are high—consider profit-taking carefully and prepare for scenarios where U.S.-Iran talks fail, leading to renewed inflation.
