Overseas Equity ETFs in H1: Semiconductors Outshine Space Themes
The real winner in overseas equity ETFs in the first half of 2026 was semiconductors. Space and other new-growth themes drew attention, but returns were led by chip-related funds. Korean investors now need to weigh won-based returns, currency moves and theme concentration risk.

The first-half verdict for overseas equity ETFs is clear: attention went to space, robotics and other new-growth themes, but returns were led by semiconductors. Korean investors spread interest across future industries, yet funds tied to AI chips, memory recovery and high-performance computing carried the stronger performance profile.
Attention on Growth, Returns in Chips
Space ETFs became a standout search and trading theme as private space, satellite communications and advanced defense technology gained visibility. But popularity and returns did not move in lockstep. Semiconductor ETFs reflected clearer earnings expectations from January through June. AI server spending, advanced packaging, foundry competition and recovering memory prices combined to put chip funds near the top of the overseas equity ETF market.
Currency Matters for Korean Investors
For Korean investors, ETF performance does not end with dollar returns. Won-based gains also depend on the won-dollar exchange rate. A stronger dollar can lift converted returns, while a weaker dollar can dilute part of the share-price gain. Investors should check the index, holdings, currency exposure, hedge status, trading hours and tax treatment before relying on simple return tables.
What to Watch Next
Semiconductor ETFs are likely to remain a central overseas equity ETF theme in the second half. Still, first-half gains raise questions about valuation and concentration. Space ETFs retain long-term growth appeal, but their short-term earnings path is less direct. The message from H1 is simple: returns followed visible earnings and the industry cycle more than headline popularity.
