SEOUL, July 28 (Reuters) – South Korea’s top financial regulator said on Tuesday that authorities would ‌consider a cap on single-stock leveraged exchange-traded ‌funds (ETF) investments for retail investors if needed, local media reports ​said.

Lee Eog-weon, chairman of the Financial Services Commission, told a meeting with local brokerages and asset managers in Seoul that the regulator would review and ‌prepare additional measures ⁠to curb the demand for the ETF products, such as putting a cap ⁠on total value of investments for each individual.

The Korean regulator last week raised the cash deposit required ​for retail ​investors to invest ​such ETFs, tied mostly ‌to either of the country’s two biggest stocks and semiconductor makers — Samsung Electronics and SK Hynix.

Shares of Samsung Electronics plunged as much as 9.7% in Seoul on Tuesday on concerns that the Korean ‌memory-chip maker may lose market ​shares to Chinese rival CXMT ​and over financing ​risks tied to AI infrastructure spending.

Shares ‌of peer SK Hynix, which ​recently listed ​its American Depositary Receipts in the U.S., slumped as much as 11.2% on Tuesday in ​Seoul. The ‌ADR fell 10% on Nasdaq on Monday to ​below its IPO price.
