"Xtrackers USD Corporate Bond UCITS ETF 2D EUR Hedged" is an exchange-traded, Euro hedged investment fund (ETF). It refers to the Bloomberg USD Liquid Investment Grade Corporate Index. This index reflects the development of 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 Xtrackers claims a total expense ratio (TER) of 0.21% per year. The yearly average divergence from the index performance (Tracking Difference) since 2017 was 2.00% per year. Therefore, the ETF was significantly more expensive than the TER suggests. Besides, the yearly tracking differences had strong variations, so their average value is not a very reliable measure.

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.
