South Korea’s National Pension Service, the nation’s biggest investor, plans to allocate more funds to overseas equities as it seeks to boost returns. The agency, which had 406 trillion won (HK$ 2.8 trillion) in assets as of March, will raise the weighting of overseas stocks to 10.5 per cent of its assets next year, up from a target of 9.3 per cent this year, said the Ministry of Health and Welfare, which oversees the agency.
