This ETN, known as UCI, aims to replicate the overall financial performance, encompassing both price movements and income generation, of the UBS Bloomberg Constant Maturity Commodity index, before any fees and expenses are factored in. It's designed to function as a broad, diversified reference point for the entire commodities asset class. The underlying index itself is composed of 28 individual futures contracts, with each specific commodity potentially featuring up to five different maturity dates.
