KOSPI Recovers from Earlier Dip

The Korea Composite Stock Price Index (KOSPI) closed 0.68 percent higher on Tuesday, adding 45.78 points to reach 6,742.74. This move reversed an earlier 2.4 percent dip during the trading session. The prior session saw the index fall over 3 percent, driven by declines in chipmakers.

This earlier downturn stemmed from renewed concerns regarding the profitability of artificial intelligence (AI)-related investments.

Foreign Investors Sell Amid Currency Weakness

Foreign investors sold a net 3.82 trillion won from Seoul shares. Conversely, individual investors bought a net 1 trillion won (approximately $723 million). Institutions also added 1.17 trillion won in net purchases. The Korean won weakened against the US dollar, quoted at 1,386.1 won as of 3:30 p.m. This represented a 3.7 won decline from the previous trading session’s close.

Sector Performance and Global Influences

Tech and auto stocks led Tuesday’s gains in Seoul. Chipmaker SK Hynix rose 0.42 percent, while Samsung Electronics remained unchanged. Top carmaker Hyundai Motor climbed 1.69 percent. Leading shipbuilder HD Hyundai Heavy Industries gained 1.98 percent. Among decliners, LG Energy Solution fell 3.45 percent, and SK Innovation shed 3.92 percent.

Analysts noted investor sentiment weighed geopolitical tensions in the Middle East against expectations for US economic data and corporate earnings.

Why it matters

The market’s immediate focus remains on major US corporate earnings results due this week, especially from chip giant Nvidia. These results will likely influence trading sentiment for Korean semiconductor firms. Furthermore, Federal Reserve Governor Kevin Warsh is scheduled to speak on Friday at the annual Jackson Hole gathering. His remarks could offer clues on the Fed's monetary policy outlook, impacting global and Asian market liquidity.
