지수 및 마감 시황
Today (August 31), the KOSPI closed at 6,820.02, up 31.14 points from the previous trading day, recording a +0.46% change. Although the market plunged in the early session due to concerns over U.S. interest rate hikes, it turned upward late in the session as expectations grew regarding shareholder return policies for major semiconductor stocks like Samsung Electronics and SK Hynix.

시장 특징주 및 주요 종목
Recent market trends show a "stock-picker's market" driven by individual corporate events (such as splits, mergers, and shareholder returns) rather than macroeconomic issues.
- Samsung Electronics & SK Hynix: Although they showed weakness in the early session, expectations for shareholder return policies played a key role in lifting the index in the late afternoon.
- Bio & Securities Stocks: As foreign net selling continued and trading volume shrank to yearly lows, the bio and securities sectors experienced relatively sluggish performances.
- Safe-Haven Sectors (Cosmetics & Banking): Amid growing overall market anxiety and a lack of momentum following the earnings season, defensive stocks like cosmetics and banking maintained a solid trend.
- Samsung, Hyundai, & SK Group Stocks: Over the past week, major conglomerate stocks generally showed weakness, acting as a downward pressure on the index.

주요 수급 및 경제 이슈
- Supply & Demand Trends: As of August 31, foreign, institutional, and retail investors all recorded net selling, with only other corporations recording net buying to support the index. Foreign net selling has continued for the fourth consecutive month since August, and trading volume hit a yearly low, significantly shrinking market liquidity.
- Exchange Rates & Interest Rates: The won-dollar exchange rate has settled in the 1,380-won range. While concerns over interest rate hikes ran high last week due to hawkish remarks by Fed Chair Jerome Powell (or Fed officials), concerns over U.S. rate hikes eased somewhat on the 31st, influencing the index's recovery.
- Macroeconomic Variables: Despite Nvidia's earnings surprise, anxieties persist across global stock markets due to lingering caution regarding AI spending and inflation. In addition, the market has adopted a watchful stance following key events such as the Bank of Korea's Monetary Policy Committee meeting and the Jackson Hole Symposium.

시장 총평 및 요약
Today's market was a classic resilience-driven session where the burden of "foreign selling" collided with the defensive factor of "large-cap shareholder returns." The contraction in trading volume and continued foreign net selling indicate that market sentiment remains subdued. However, with Samsung Electronics and SK Hynix defending the index, the KOSPI managed to recover the 6,800 mark. Moving forward, the market is expected to see a differentiated stock-driven trend influenced more by individual corporate shareholder return policies or earnings momentum rather than macroeconomic indicators.
