"Lyxor MSCI World (LUX) UCITS ETF" is an exchange-traded investment fund (ETF). It refers to the MSCI World Index. This index reflects the development of 1513 world wide stocks and is therefore very well diversified. The ETF replicates its index using synthetic replication, so the index performance is realized using a swap contract. The ETF's earnings (dividends) are distributed to the investors. The fund company Lyxor claims a total expense ratio (TER) of 0.20% per year. The yearly average divergence from the index performance (Tracking Difference) since 2009 was 0.01% per year. Therefore, the ETF was less expensive than the TER suggests.
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.
