SEOUL, Jan 2 (Reuters) - Round-up of South Korean financial markets:
** South Korean stocks ended lower on Thursday in their first trading session of the year, as investors booked profits from market heavyweights, while awaiting details of the Phase 1 U.S.-China trade deal. The Korean won and the benchmark bond yield fell.
** U.S. President Donald Trump said on Tuesday that Phase 1 of trade deal with China would be signed on Jan. 15 at the White House, though considerable confusion remains about the details of the agreement.
** The Seoul stock market’s main KOSPI ended down 22.50 points, or 1.02%, at 2,175.17.
** The index dropped though positive news outweighed, said Na Jeong-hwan, an analyst at DS Investment & Securities. It looks like a short-term loss caused by profit-booking from market heavyweights like Samsung Electronics, he added.
** Eight out of the 10 biggest stocks listed on the KOSPI market ended lower, with Samsung Elec shares losing more than 1%.
