"Xtrackers FTSE 250 UCITS ETF 1D" is an exchange-traded investment fund (ETF). It refers to the FTSE 250 Index. This index reflects the development of 250 British stocks and is therefore relatively well diversified. The ETF replicates its index using full physical replication, so it contains all the securities of its reference index. The ETF's earnings (dividends) are distributed to the investors. The fund company Xtrackers claims a total expense ratio (TER) of 0.15% per year. The yearly average divergence from the index performance (Tracking Difference) since 2009 was 0.43% per year. Therefore, the ETF was more expensive than the TER suggests.
