"iShares MSCI China A UCITS ETF USD (Acc)" is an exchange-traded investment fund (ETF). It refers to the MSCI China A Inclusion Index. This index reflects the development of Chinese 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 automatically reinvested (accumulated). The fund company iShares claims a total expense ratio (TER) of 0.40% per year. The yearly average divergence from the index performance (Tracking Difference) since 2016 was -0.62% per year. Therefore, the ETF was significantly less expensive than the TER suggests and even exceeded the index performance. However, 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.
