Foreign investors of South Korean stocks extended their selling spree for the fifth consecutive month in March as concerns over the slowing Chinese economy and protracted Ukraine conflict kept them from betting on risky assets, the financial watchdog said Sunday. Overseas investors offloaded a net 1.25 trillion won (US$1.19 billion) worth of local stocks in March, compared with a net selling of 1.23 trillion won a month earlier, according to the Financial Supervisory Service (FSS).
