"Invesco FTSE RAFI All World 3000 UCITS ETF Dist" is an exchange-traded investment fund (ETF). It refers to the FTSE RAFI All World 3000 Index. This index reflects the development of world wide stocks . The ETF replicates its index using physical replication with sampling, so it contains the most important securities of its reference index. The ETF's earnings (dividends) are distributed to the investors. The fund company Invesco claims a total expense ratio (TER) of 0.39% per year. The yearly average divergence from the index performance (Tracking Difference) since 2008 was 0.71% per year. Therefore, the ETF was more expensive than the TER suggests. Besides, the yearly tracking differences had strong variations, so their average value is not a very reliable measure.
