Foreigners purchased a net 148.8 billion won worth of local shares to back up the positive mode, making up for a net sale of 56.1 billion won and 110.2 billion won by institutions and individuals, respectively. Lee Jae-won, an analyst from Shinhan Securities Co., said foreigners focused on Korean semiconductor shares like SK hynix following an overnight U.S. stock rally led by Nvidia.
