SEOUL-- South Korean shares traded 0.25 percent higher late Friday morning as investors picked up battered tech and bio shares amid lingering concerns over the U.S. central bank's aggressive monetary tightening.

The Korea Composite Stock Price Index had risen 6.04 points to 2,421.65 as of 11:20 a.m.

Retail investors went on a net buying mode, following a big drop in the previous session, while institutions and foreigners sold shares.

Overnight, U.S. shares ended mixed. The Dow Jones Industrial Average rose 0.46 percent, while the tech-heavy Nasdaq shed 0.26 percent.

Eyes are on the U.S. payroll data for August due on Friday (U.S. time), as the job report is one of the key factors for the Federal Reserve's monetary policy.

The Fed has said it will continue interest rate hikes for some time to curb inflation. In July, the Fed raised its key interest rate by 75 basis points for the second straight month.

Large-cap stocks in Seoul traded mixed.

Market bellwether Samsung Electronics lost 0.34 percent, and No. 2 chipmaker SK hynix shed 0.11 percent.
