Traders Pour Record Cash Into BlackRock Fund Buying South Korea

A BlackRock Inc. fund packed with South Korean chipmakers pulled in its biggest inflow on record on Wednesday as investors doubled down on Asia’s semiconductor rally.

The $13 billion iShares MSCI South Korea ETF, known by its ticker EWY, absorbed a $281 million inflow, the most in the fund’s over 25-year history. The US-listed ETF’s top holdings are chip heavyweights Samsung Electronics Co. and SK Hynix Inc., which have pushed the country’s Kospi stock index up more than 30% year-to-date to an all-time high. EWY has taken in over $3 billion in the past three months, according to data compiled by Bloomberg.
