EURL is a 3x levered play on the FTSE Developed Europe Index, a market-cap-weighted index of total market stocks in developed Europe. The usual caveats for geared funds apply emphatically for 3x gearing: The fund rebalances its exposure on a daily basis, and is directly affected by issues of path dependency and compounding. As a result, its long-term returns are unlikely to achieve the 3x multiple. Returns are helped by strong trends and hurt by volatility. EURL isnt appropriate for buy-and-hold investors. Note: The fund switched underlying indexes on August 22, 2016 to a slightly different and arguably better FTSE index. The index tracked at 1x by Vanguard`s VGK includes small-caps, thereby providing more complete coverage of the space.
