South Korean shares jumped more than 1 percent Monday on the back of advances in tech shares and eased social distancing measures against the new coronavirus in the country. The Korean won rose against the US dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) rose 31.22 points, or 1.3 percent, to close at 2,427.91.

Trading volume was moderate at about 953 million shares worth some 11.9 trillion won ($10.1 billion), with gainers outnumbering losers 645 to 218.

Foreigners bought a net 143 billion won, while retail investors sold a net 288 billion won. Institutions purchased a net 96 billion won.

The index exceeded the 2,400-point mark, increasing for the third consecutive session.

Chipmakers continued to gain despite lingering valuation pressure.

"The Nasdaq and the KOSPI are going through a (price) adjustment process," Hana Financial Investment analyst Lee Jae-man said.

"Such adjustment is likely to come to an end, if the US Federal Reserve rolls out some concrete directions about the average inflation rate Thursday, and ensure the longevity of the current low-interest rate," he added.

Investor sentiment also improved as the South Korean government eased the social distancing level to Level 2 in the greater Seoul area Monday.

Large caps closed mixed in Seoul.
