surpassing the 26‑year‑old iShares MSCI Korea ETF (EWY). Over the same period
EWY logged roughly $2bn of net outflows; earlier in 2026 EWY had drawn about
$6bn of inflows. DRAM allocates more than 90% of its weight to memory names —
Samsung Electronics, Micron Technology, SK Hynix, SanDisk, Seagate Technology,
Western Digital and Kioxia — and its holdings overlap with EWY by roughly 46%.
