"SPDR Russell 2000 U.S. Small Cap UCITS ETF" is an exchange-traded investment fund (ETF). It refers to the Russell 2000 Index. This index reflects the development of 2003 US American stocks with low market capitalization and is therefore very well diversified. 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 SPDR claims a total expense ratio (TER) of 0.30% per year. The yearly average divergence from the index performance (Tracking Difference) since 2015 was -0.15% per year. Therefore, the ETF was 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.
