This ASX ETF tracks the performance of the MSCI Korea 25/50 Index, before fees and expenses.
The index is designed to measure the performance of Korean large-cap and mid-cap companies.
The Korean economy saw modest growth in 2025, however this fund was able to capture some of the record breaking exports from last year.
