Wall Street stock market trading floor with digital screens showing market data - Profit-taking ahead of NVIDIA earnings: Amid caution ahead of NVIDIA's earnings announcement, profit-taking sell-offs swept across technology and semiconductor sectors, setting the market tone. This indicates that investors are adopting a wait-and-see approach until they gain clearer conviction on mega-cap tech earnings.
- Iran sanctions and falling oil prices: US Treasury Secretary Scott Bessent announced new sanctions against Iran as part of a plan to isolate its economy ("Economic D-Day"), but the market absorbed the news without major shocks. Consequently, crude oil prices edged lower.

Additionally, Bitcoin neared the $80,000 threshold, signaling a partial recovery in risk appetite.
Key Themes and Issues in the Korean Market
- Institutional buying flows into construction and machinery: On August 25, the KOSPI opened lower following the previous day's tech weakness in the US, but broader Asian investor sentiment recovered on expectations of stable interest rates and oil prices. Notably, institutional buying focused on construction and machinery sectors propelled the index up by +45.78 points (+0.68%), maintaining a positive trajectory.

This reflects market anxieties regarding the sustainability of the global AI CapEx cycle directly impacting South Korea's heavyweight chip makers.
- Samsung Electronics shares struggle despite record shareholder returns: Despite implementing record-high shareholder return policies, Samsung Electronics has seen its share price trade weakly. This suggests that global macroeconomic uncertainties and investors' conservative views on the semiconductor industry outlook are taking precedence over improving corporate fundamentals.
