US Market Analysis & Korea Daily Briefing — 2026-06-27
US Market Summary (Yesterday)
1. Tech stocks rally on memory chip supercycle hopes Micron’s better-than-expected earnings yesterday provided a strong signal that the memory market is entering a supercycle. This, combined with surging AI demand, served as a major tailwind for the semiconductor sector.
2. Inflation and rate hike fears weigh on tech The yield on the US 10-year Treasury note climbed to 4.38%, fueling fears of rate hikes and triggering a sell-off in major tech stocks. The S&P 500 and Nasdaq have now declined for three consecutive days, with tech stocks seeing the deepest corrections.
3. Investors rotating into defensive sectors As the S&P 500 struggles to find its footing, investors are rotating into defensive plays. With oil prices near their lowest levels, there is a clear trend of demand shifting toward energy and utility stocks.
Key Themes and Issues in the Korean Market
1. Extreme volatility: Three circuit breakers in one month On June 26, the KOSPI market triggered a circuit breaker three times. This marks the first time in history that three circuit breakers have been triggered within a single month, following similar events on the 8th and 23rd. Investor sentiment remains highly unstable, evidenced by the rapid swing from a buy-side sidecar to a sell-side sidecar yesterday.
2. KOSDAQ hits 'year-to-date low' for 4th straight day, plunging 4.82% As of 2:20 PM on June 26, the KOSDAQ index stood at 845.104, down 4.82% from the previous day. The index has been continuously hitting new lows since falling below the 900-point mark for the first time in history on the 23rd, and the KOSPI also closed lower.
3. Semiconductor dominance continues—Samsung and SK Hynix lead the way Even in a falling market, semiconductors are the only sector showing resilience. Samsung Electronics and SK Hynix are acting as market leaders, driven by expectations of rising AI memory demand and price recovery. They are outpacing other sectors in earnings improvement, and are expected to maintain their lead for the time being.
Today's Featured Stocks
1. Samsung Electronics (005930)
- Reason for interest: With the memory supercycle signaled by Micron’s strong earnings, a recovery in chip prices is becoming tangible. Expect increased HBM (High Bandwidth Memory) shipments due to AI demand. It remains a top choice for institutional and foreign investors even amid extreme market volatility.
2. SK Hynix (000660)
- Reason for interest: Like Samsung, this company is a direct beneficiary of the memory market turnaround. Despite recent profit-taking pressure, its earnings momentum remains strong, and it maintains a stable supply-demand structure thanks to steady net buying by foreign investors.
3. Samsung Electro-Mechanics (009150)
- Reason for interest: The company is benefiting from AI server demand through its next-gen high-density substrate business (FC-BGA, embedded PCB, glass core substrates). It saw roughly 1.9 trillion KRW in net buying from foreign investors in June, and profitability is expected to improve as its technology takes the lead.
