Understand the exposure
US equity ETFs: exposure, concentration and currency
Learn how US equity ETF benchmarks differ, why US exposure can overlap with global funds, and what Irish investors should check before buying.

The short answer
US equity ETFs can follow very different markets and strategies. An S&P 500 fund, a Nasdaq-100 fund and a small-company fund do not offer the same exposure. Compare their rules and your existing holdings before looking at fees.
Four checks before comparing funds
| Check | What to understand |
|---|---|
| Benchmark | Check the eligible companies, exchanges, sectors and weighting rules rather than treating every US ETF as interchangeable. |
| Overlap | A global equity fund may already own many US companies. Adding a US fund can increase an existing exposure. |
| Risk | Equity prices, sector concentration, valuation and currency movements can all affect returns. A broad label is not a risk guarantee. |
| Listing and class | A euro trading line does not itself hedge US-dollar exposure. Match the ISIN, income treatment, class currency and any explicit hedge. |
