South Korean stocks shed 0.41 percent on Friday ahead of the release of a U.S. jobs report that could give hints to the Federal Reserve's rate decision, although some bio shares helped erase some of the earlier losses, analysts said.

The local currency fell against the U.S. dollar.
  

The benchmark Korea Composite Stock Price Index fell 8.34 points to 2,041.07. Trading volume was light at 436.7 million shares worth 4.34 trillion won ($3.8 billion), with losers far surpassing winners 552 to 260.
  

Analysts said a solid U.S. jobs report could give the Federal Reserve confidence to lift the key interest rate next month, which could dampen appetites for risky assets. The report is due later in the day.
  

"Investors fretted over the rising possibility of a U.S. rate hike, trying to lock in from recent surges," Ma Ju-ok, an analyst at Kiwoom Securities, said. "Tech and shipbuilders, faced with downbeat business prospects, weighed down the benchmark index."
  

Tech shares fell on expectations that the supply glut in dynamic random access memory (DRAM) would continue into the fourth quarter.

Shipbuilders were depressed after logging massive deficits in the third quarter due to order cancellations and delayed construction schedules in offshore facilities.
  

Hyundai Heavy Industries, the world's top shipyard, slumped 2.11 percent to 97,500 won, and No. 2 Daewoo Shipbuilding & Marine Engineering fell 1.5 percent to 6,580 won.
  

Bio and health care shares rallied after Hanmi Pharmaceutical announced a license agreement with French drugmaker Sanofi to develop diabetes treatments, a deal worth over $4 billion. Its shares soared by the daily limit of 30 percent as soon as the market opened and held onto the ground throughout the session.
  

Chong Kun Dang jumped 12.66 percent to 81,000 won and LG Life Sciences, a health care unit under LG Group, soared 12.17 percent to 71,900 won.
  

The local currency ended at 1,141.90 won against the greenback, down 3.4 won from Thursday's close.
