"Invesco EQQQ Nasdaq-100 UCITS ETF EUR Hdg Acc" is an exchange-traded investment fund (ETF). It refers to the Nasdaq 100 Index. This index reflects the development of 103 US American stocks and is therefore relatively well diversified. The ETF replicates its index using full physical replication, so it contains all the securities of its reference index. The ETF's earnings (dividends) are automatically reinvested (accumulated). The fund company Invesco claims a total expense ratio (TER) of 0.35% per year. The yearly average divergence from the index performance (Tracking Difference) since 2018 was 2.90% 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.
