South Korean shares jumped by more than 1 percent to extend their winning streak to a fourth session Monday, as investor sentiment improved on hopes for fresh economic stimulus in the United States. The Korean won rose against the US dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) rose 30.11 points, or 1.29 percent, to close at 2,358.0.

Trading volume was moderate at about 746 million shares worth some 10.5 trillion won ($9 billion), with gainers outnumbering losers 647 to 211.

Foreigners bought a net 169 billion won, ending their seven-session selling streak, while retail investors sold a net 548 billion won. Institutions purchased a net 388 billion won.

The gains were largely attributed to optimistic statements by key US officials related to the new $2.2 trillion stimulus proposal.

Over the weekend, US President Donald Trump tweeted his support for the stimulus bill, with House Speaker Nancy Pelosi showing stronger confidence about the stimulus talks.

"The stock markets are paying attention to policy options that Trump can come up with (during his campaign)," Hana Financial Investment analyst Lee Jae-man said.

"The increasing possibility of stimulus agreement seems to be holding up the stock market against the political uncertainties," he added.
