SEOUL, Sept 17 (Reuters) - Round-up of South Korean financial markets:
** South Korean shares ended higher on Friday as upbeat U.S. retail sales data boosted sentiment, though investors refrained from placing big bets ahead of the country's three-day holiday. The won weakened, while the benchmark bond yield rose.
** The KOSPI closed up 10.42 points, or 0.33%, at 3,140.51, after logging a 0.74% decline in the previous session.

** Chip giants Samsung Electronics and SK Hynix led gains on the benchmark, adding 1.45% and 2.88%, respectively, while web portal operator Naver inched up 0.25%.
** Meanwhile, shares in Hyundai Heavy Industries leapt 85% from their initial public offering price in Friday's trading debut.
** Foreigners were net buyers of 45.8 billion won ($38.94 million) worth of shares on the main board.
** U.S. retail sales unexpectedly increased in August, which could temper expectations for a sharp slowdown in economic growth in the third quarter.
** Investors now await the U.S. Federal Reserve's upcoming policy meeting for more clues on the tapering of its bond-buying programmes.
** South Korea's financial markets will be closed from Monday to Wednesday due to the Korean thanksgiving Chuseok holiday.
