According to The Korea Herald, citing filings submitted to the U.S. Securities and Exchange Commission, the National Pension Service (NPS) of South Korea held shares in 553 U.S. listed companies as of the end of September, with a total portfolio market value of $158.74 billion, an increase of $3.66 billion from three months earlier. The report linked the rise in the dollar-denominated market value to the performance of mega-cap tech stocks, while noting that the portfolio's market value denominated in South Korean won had declined; the aforementioned change in the dollar-denominated market value does not equal the net buying amount over the same period.
