South Korea's stock exchange ended its three-day winning streak Friday on valuation pressure after hitting another new high the previous session. The Korean won fell against the US dollar.
The benchmark Korea Composite Stock Price Index (KOSPI) retreated 20.21 points, or 0.64 percent, to close at 3,140.63 points.
Trading volume was moderate at about 1.1 billion shares worth some 24 trillion won ($21.7 billion), with losers outnumbering gainers 476 to 384.
Foreigners sold a net 270 billion won, while retail investors purchased a net 1.6 trillion won. Institutions dumped a net 1.4 trillion won.
Trading was choppy on the key index, following the previous session's record finish.
Local stocks rebounded late morning on hopes of a global economic rebound, backed by developments related to the $1.9 trillion US economic aid package.
But increasing sell-offs of local stocks by institutions and foreigners eventually took the KOSPI into negative terrain.
