"UBS ETF (IE) MSCI World UCITS ETF (USD) A-acc" is an exchange-traded investment fund (ETF). It refers to the MSCI World Index. This index reflects the development of 1429 world wide stocks 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 UBS ETF claims a total expense ratio (TER) of 0.10% per year. The yearly average divergence from the index performance (Tracking Difference) since 2020 was 0.15% per year. Therefore, the ETF was slightly more expensive than the TER suggests.
