# Why iShares MSCI Korea ETF (EWY) rose 8.26% on August 4, 2026

iShares MSCI Korea ETF (EWY) rose 8.26% on August 4, 2026 — Memory supply deals lift Korea tech sentiment broadly.

## What happened

The iShares MSCI Korea ETF surged 8.3% alongside a broad rally in Korean tech stocks, driven by Samsung and SK Hynix expanding binding memory supply deals as the HBM and DRAM shortage persists.

## Why it moved

Memory supply deals lock in pricing power and order visibility for Samsung and SK Hynix, the fund's largest holdings; the ETF rises on beta exposure to this sector-wide margin expansion and AI-cycle tailwind.

## Why it matters

Korea Tech theme benefits as the memory bottleneck deepens, making Korean chipmakers the gating constraint on AI infrastructure capex — a multi-quarter structural advantage.

## What would break the thesis

If memory prices roll over or new capacity announcements flood the market, Korean export upside fades and the ETF retraces.
