SEOUL, Feb 23 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares rose on Friday and logged their fifth straight week of gains, buoyed by a global rally that has seen stocks from Asia and Europe to the U.S., hitting all-time highs this week. The won weakened, while the benchmark bond yield rose.

** The benchmark KOSPI closed up 3.43 points, or 0.13%, at 2,667.70. For the week, the index closed up 0.7%.

** Among index heavyweights, chipmaker Samsung Electronics fell 0.27% and peer SK Hynix gained 3.13%, while battery maker LG Energy Solution slid 1.59%.

** Hyundai Motor added 0.21% and sister automaker Kia Corp lost 0.75%, while search engine Naver and instant messenger Kakao were down 0.74% and down 1.38%, respectively.

** Japanese stocks raced to a record peak on Thursday, breaking levels last seen in 1989 during the halcyon days of the bubble economy, as cheap valuations and corporate reforms lure foreign money looking for alternatives to battered Chinese markets. ** South Korea hopes to mirror Japan's efforts to boost the value of its companies as its neighbour's stock market surges to a record high, with measures Seoul hopes will narrow a "Korea discount" on stock prices.

** Of the total 935 traded issues, 342 shares advanced, while 518 declined.

** Foreigners were net buyers of shares worth 148.8 billion won on the main board on Friday.

** The won ended onshore trade at 1,331.0 per dollar, 0.17% lower than its previous close at 1,328.7.

** In offshore trading, the won was quoted at 1,330.6 per dollar, down 0.3% on the day, while in non-deliverable forward trading, its one-month contract was quoted at 1,328.4.

** In money and debt markets, March futures on three-year treasury bonds fell 0.07 point to 104.58.
