SEOUL, Feb 2 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares rose on Tuesday, driven by heavyweight chipmakers and foreign buying, following a tech-led Wall Street rebound overnight. Both the won and the benchmark bond yield edged down.

** The KOSPI closed 40.28 points, or 1.32%, higher at 3,096.81, after gaining as much as 2.7% in early trade to hit a one-week high. The index jumped 2.7% on Monday, supported by robust trade data and fading volatility concerns.

** Chip giants Samsung Electronics and SK Hynix surged as much as 4.1% and 5.2%, respectively, while another tech heavyweight, Naver, gained 4.2% to a record closing high.

** The S&P 500 index registered its biggest daily percentage gain since Nov. 24 on Monday after a steep sell-off last week, and technology-related shares led the advance.

** “U.S. stimulus package discussion will be closely watched this week, with the size to be somewhere between the Republican’s $618 billion and the Democrat’s $1.9 trillion,” said Choi Yoo-june, analyst at Shinhan Investment Corp.

** South Korea’s inflation sped up in January, beating forecasts and offering more signals of a mild recovery.

** Meanwhile, the country’s ruling party said on Tuesday it will prepare a fourth round of COVID-19 cash handouts and an extra budget of sufficient scale.

** Foreigners were net buyers of 195.5 billion won ($175.01 million) worth of shares on the main board.
