"Amundi S&P 500 UCITS ETF - EUR (C)" is an exchange-traded investment fund (ETF). It refers to the S&P 500 Index. This index reflects the development of 503 US American 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 automatically reinvested (accumulated). The fund company Amundi claims a total expense ratio (TER) of 0.15% per year. The yearly average divergence from the index performance (Tracking Difference) since 2011 was -0.28% 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.
