"iShares Core EURO STOXX 50 UCITS ETF EUR (Dist)" is an exchange-traded investment fund (ETF). It refers to the EURO STOXX 50 Index. This index reflects the development of only 50 European stocks and is therefore not very 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 iShares claims a total expense ratio (TER) of 0.10% per year. The yearly average divergence from the index performance (Tracking Difference) since 2008 was -0.44% per year. Therefore, the ETF was significantly less expensive than the TER suggests and even exceeded the index performance.
Comparing Tracking Difference, Total Expense Ratio and fund size
Every bubble represents an ETF. The further to the right it is, the higher (worse) is its tracking difference. The further up it is, the higher the total expense ratio specified by the fund company. The bubble's area represents the fund volume.
