This ETF is one option available for investors seeking to establish exposure to the economies of the euro zone, a sub-set of general European equity exposure. As such, FEZ is more than likely too targeted for long-term portfolios; broad EAFE funds such as VEA or even all-inclusive European ETFs such as VGK are probably better building blocks for buy-and-holders. But this fund can potentially be useful for implementing short-term tactical tilts, and has the potential to be a component of long/short trades as well. FEZ maintains a few biases; it is almost exclusively comprised of large cap stocks, and financials receive a hefty allocation. This product is also not the greatest in terms of diversification; with just 50 holdings, FEZ includes only a small fraction of Euro zone stocks. EZU offers similar Euro zone exposure with greater depth, as that fund holds more than 200 individual names and exhibits a more balanced sector and market cap breakdown.
