SK Hynix

Shares of SK Hynix fell 3.8% on Friday to close at 1,783,000 ₩, weighed down by rising energy costs and higher US interest rates (10-year yield above 4.95%), which dampened risk appetite in the semiconductor sector. Additional selling pressure came from a warning by the Bank of Korea that foreign hedge funds, leveraged ETFs and total return swaps are amplifying leveraged exposure to stocks like SK Hynix. Domestic investors were net sellers of SK Hynix by more than ₩8 trillion in the first ten days of September, reducing local buying support and pushing the KOSPI down 2.4%. » More on de.investing.com
