South Korea's equity-linked securities (ELS) saw a net outflow of funds last month as investors fretted over growing downward pressure in the stock market following a sharp rally, data showed Monday.

Deposits at ELS issued by local brokerage houses were estimated at 60.22 trillion won (US$55.69 billion) as of April 29, 1.31 trillion won down from the end of March, according to the data compiled by the Korea Securities Depository (KSD).
