受市场对韩国两大芯片巨头——三星电子与SK海力士推出大规模股东回报计划的期待提振，首尔股市周五收盘走高，韩元兑美元汇率上涨。
韩国综合股价指数（KOSPI）收盘上涨60.37点，涨幅0.88%，报6912.95点，盘中最高触及6954.12点。
大信证券分析师李京敏表示：“SK海力士与三星电子的股东回报计划推升了韩国本土股市，盖过了外部不确定性带来的影响。”
SK海力士于周三公布股东回报方案，计划回购价值约40万亿韩元（折合288亿美元）的普通股。
市值龙头三星电子也预计将于当日晚些时候公布最高规模达110万亿韩元的股东回报方案。
不过外部不确定性压制了股市进一步上行的空间。尽管美国财政部意外推出债券回购操作，但此举未能消除市场对通胀与政府债务挥之不去的担忧，反而推高了债券收益率。
