DBP is the first precious-metals ETF, and it tracks a rules-based index composed of futures contracts on two of the well-known precious metals, gold and silver. The underlying index is designed to reduce the effects of contango by selecting futures contracts that, by its rule, have the highest implied roll yield for each commodity. Like our benchmark, it allocates over 80% of its portfolio to gold and the remainder to silver, ignoring platinum and palladium. The only big difference between DBP and our benchmark is that DBP holds contract based on the shape of the futures curve, while our benchmark uses a simple front-month futures strategy. Structured as a commodity pool, investors should expect a K-1 at tax time. The fund and the index are rebalanced and reconstituted annually in November.
