Samsung Electronics and SK Hynix shares fell sharply as rising U.S. bond yields and oil prices triggered a massive sell-off by foreign and institutional investors.
What Happened
Semiconductor Stocks Decline: Samsung Electronics and SK Hynix saw their share prices drop by 3.53% and 2.21%, respectively, on September 11. The decline was driven by a broader downturn in the technology sector and rising macroeconomic pressures.
Impact of U.S. Market: U.S. markets faced a fourth consecutive day of losses following the latest Producer Price Index (PPI) data, which fueled concerns over potential Federal Reserve interest rate hikes. The 10-year U.S. Treasury yield surged past 4.95%, creating a difficult environment for tech stocks.
Foreign and Institutional Selling: Foreign and institutional investors led the selling spree, with foreign investors offloading over 900 billion KRW of Samsung Electronics and over 1 trillion KRW of SK Hynix shares. These two companies were the top targets for net selling by both groups during the session.
Market Outlook: The combination of rising oil prices and high interest rates continues to weigh on investor sentiment. Market participants remain cautious, closely monitoring upcoming FOMC decisions and further economic indicators for signs of stabilization.
