EZU holds a well-run and accessible portfolio of large- and mid-cap Eurozone companies from 10 developed countries in the EMU. By design, it excludes firms from countries that don't use the euro, most notably the UK, Switzerland, and Sweden that account for roughly half of European market cap. This distinction steers the fund away from the broader market, which could appeal to currency-focused investors. The fund is heavily concentrated in France and Germany, but sector biases are modest. The index is reviewed quarterly to reflect changes in the markets in a timely manner and rebalanced semiannually.
