Seoul shares ended lower Monday, breaking their four-day winning streak amid profit-taking moves and lingering rate hike concerns. The South Korean won declined against the US dollar.

After choppy trading, the benchmark Korea Composite Stock Price Index shed 9.3 points, or 0.35 percent, to finish at 2,619.

Trading volume was moderate at 540.02 million shares worth 11.48 trillion won ($9.06 billion), with decliners outpacing gainers 511 to 370.

Institutions and foreigners offloaded a net 232.29 billion won and 200.39 billion won worth of stocks, respectively, while retail investors bought a net 426.80 billion won worth of shares.

Wall Street finished mixed Friday as US Federal Reserve officials said it was too early to declare victory on inflation, indicating more rate hikes could come to bring inflation down to its 2 percent target.

The Fed is widely expected to raise its policy rate later this month, which would bring the rate to the 5.25-5.5 percent range.
