"iShares Gold Producers UCITS ETF USD (Acc)" is an exchange-traded investment fund (ETF). It refers to the S&P Commodity Producers Gold Index. This index reflects the development of only 46 US American Precious Metals stocks and is therefore not very 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 iShares claims a total expense ratio (TER) of 0.55% per year. The yearly average divergence from the index performance (Tracking Difference) since 2012 was 0.50% per year. Therefore, the ETF was slightly less expensive than the TER suggests.
