SEOUL, May 24 (Yonhap) -- South Korean stocks ended nearly flat after a seven-day rise Wednesday, as uncertainties linger over talks on the United States' debt ceiling to avoid a federal default. The local currency fell against the U.S. dollar.
The benchmark Korea Composite Stock Price Index shed 0.10 points, or 0.0 percent, to close at 2,567.45. Trading volume was moderate at 1.06 billion shares worth 7.79 trillion won (US$5.91 billion), with losers outpacing gainers 460 to 397.
Institutions sold a net 185.5 billion won worth of shares, while retail and foreign investors bought a net 132.165 billion won and 94.23 billion won worth of shares, respectively.
The index opened slightly lower and moved within a tight range before ending unchanged, as investors moved to lock in profits from recent gains amid little progress about the U.S. debt ceiling issue.
U.S. President Joe Biden and House Speaker Kevin McCarthy said late Monday (local time) that they had productive talks, but no agreement has been made.
"Investor sentiment remained fragile as fears about the negotiation have spread further and strong U.S. manufacturing activity data raised concerns about further interest rate hikes," Kiwoom Securities analyst Han Ji-young said.
U.S. Composite PMI Output Index, which tracks the manufacturing and services sectors, rose to a 13-month high in May, according to foreign media reports, which fueled expectations that the Federal Reserve would continue its interest rate hike cycle.
