Short-term volatility in South Korea's and Taiwan's stocks hasn't changed the underlying earnings outlook for these markets, says T. Rowe Price's Agnes Ng in a note. The structural demand from AI infrastructure investment remains intact for both markets given their importance across semiconductors, memory, advanced packaging and related supply-chain components, the portfolio specialist says. Still, investors should brace for larger two-way market moves, as the increasing use of leveraged products could amplify volatility even as company fundamentals remain broadly unchanged, she says. Such products include single-stock leveraged exchange-traded funds, which South Korea introduced earlier this year.(megan.cheah@wsj.com)
