SEOUL, Oct 21 (Reuters) - Round-up of South Korean financial markets: ** South Korean shares fell for a second session on Thursday as investors weighed the outlook for China's property sector over ailing developer Evergrande's financial strains and elevated inflation. The Korean won weakened, while the benchmark bond yield fell.

** The benchmark KOSPI fell 5.80 points, or 0.19%, to 3,007.33 as of 06:32.

** Among the heavyweights, technology giant Samsung Electronics fell 0.14% and peer SK Hynix fell 1.63%, while LG Chem fell 4.05% and Naver rose 0.74%.

** Investors seem to be worried about China's property market outlook and growth ahead, while preliminary trade data from Korea was positive and capped further losses, said Lee Kyoung-min, an analyst at Daishin Securities.

** South Korea's exports for the first 20 days of October soared 36.1% from a year earlier, data showed on Thursday, easing concerns about supply-chain disruptions caused by the energy crisis in neighbouring China.
