# Why iShares MSCI Korea ETF (EWY) rose 2.83% on October 27, 2026

iShares MSCI Korea ETF (EWY) rose 2.83% on October 27, 2026 — AI optimism after US chip gains lifts Korea.

## What happened

South Korea's stock market opened higher as AI optimism returned following US chip gains, and EWY rose 2.8%. The move reflects spillover from US tech strength into Korean equities.

## Why it moved

Risk-on AI sentiment from the US chip rally spilled into Korea, where semis are a large share of the index, so the ETF moved with that sentiment.

## Why it matters

EWY is the broad Korea Tech theme in ETF form, where AI memory demand has been the key driver of Korean market flows.

## What would break the thesis

If US AI leaders reverse sharply or Korea-specific selling overwhelms the open, the spillover fades. The theme's broader breakdown on policy and rate concerns is the main risk to the thesis.
