삼성증권 analyst 김종민 viewed corporate earnings power as explaining the market. His assessment was that even with the burden of high interest rates, high inflation, and a high exchange rate, an upward trend does not break easily if corporate results provide support. This explains today’s strength in semiconductors and export-oriented large caps. The media citation basis is 비즈워치 2026-05-26.

KB증권 Research Headquarters investment strategy information team analyst 임정은 viewed that attempts to settle above the KOSPI 8,000 line could continue as macro uncertainty eases and supply-demand improves. She pointed to the need to watch tomorrow’s single-stock leveraged ETFs, the Korean Monetary Policy Board meeting on 28일, and U.S. PCE inflation together. The media citation basis is 뉴스핌 2026-05-26.

신한투자증권 analyst 강진혁 viewed that expectations for U.S.-Iran negotiations stabilized oil prices and interest rates, while waiting funds entered after the holiday and helped the market settle above the 8,000 line. This explains today’s institutional buying and risk-asset appetite. The media citation basis is 이데일리 2026-05-26.

대신증권 analyst 이경민 explained that expectations for single leveraged ETF listings and demand for AI servers were attached together to the semiconductor sector. This aligns with strength in Samsung Electronics, SK hynix, DB HiTek, and Jusung Engineering. The media citation basis is 뉴스2데이 and a cited Daum article on 2026-05-26.

Common ground: The assessment is that large-cap semiconductors and improved supply-demand produced today’s KOSPI close above the 8,000 line.

Difference: 삼성증권 focused more on corporate earnings, while KB증권 focused more on this week’s events. 신한투자증권 put oil-price and interest-rate stability further forward.

Tomorrow’s link: Fund flows on the first listing day of the ETFs, profit-taking in Samsung Electronics and SK hynix, and movements around the 1,500원 level in the USD/KRW exchange rate should be watched first.

Among the major DART items checked from after 15:30 through 19:50, large disclosures capable of shaking the entire market were limited.

The confirmed post-close disclosure was GeneOne Life Science’s 17:10 corrective disclosure on a capital reduction decision. It has the character of an individual stock risk. The basis is DART 2026-05-26 17:10.

For after-hours single-price sharp gainers and decliners, a confirmed table matching the date and time could not be found through public search. No figures are included in the text.

USD/KRW is 1,501.20원. It fell 11.04원, or 0.73%, from the previous day. The intraday range is 1,500.39~1,518.78원. The basis is the Investing.com real-time exchange rate, displayed as 2026-05-26 06:50:50 U.S. Eastern.

Fund flows on the first listing day of the Samsung Electronics and SK hynix single-stock leveraged ETFs should be watched. It will be a day to confirm whether today’s rising semiconductor names continue to receive money tomorrow.

Whether institutional buying continues above the KOSPI 8,000 line should be watched. Today, institutions bought 9,111억원. If this flow breaks, the index may become vulnerable to swings.

Whether the USD/KRW exchange rate defends the 1,500원 line should be watched. If the exchange rate falls, the burden from foreign selling may ease. If it jumps again, profit-taking in large caps may appear.

Caution ahead of the Bank of Korea Monetary Policy Board meeting on 28일 and U.S. PCE inflation should be watched. Interest-rate and inflation numbers directly affect valuations for growth stocks and semiconductors.

The KOSDAQ was pushed back after failing to break above the 1,200 line. Tomorrow, it should be confirmed whether individual buying continues and whether money spreads into biotech and secondary batteries.

• Confirmed ranking of after-hours single-price sharp gainers and decliners: A search for '시간외 단일가 급등락 오늘 2026년 05월 26일' did not confirm a reliable table matching the date and time.

• Original Korea Exchange investor-by-investor trading source: Media-cited figures were used because direct access to the original KRX table was restricted.

• Seoul Money Brokerage Services official 15:30 closing rate: The confirmed original source for today could not be found through public search, so the Investing.com real-time USD/KRW figure was shown separately.
