The Invesco BulletShares 2035 Municipal Bond ETF (BSMZ) is an exchange-traded fund engineered to replicate the performance of the Invesco BulletShares USD Municipal Bond 2035 Index. This ETF allocates at least 80% of its total capital to municipal debt instruments that constitute its benchmark index. The underlying index aims to measure the returns of a collection of municipal bonds, denominated in U.S. dollars, which are issued by American states, their agencies, or local governments, all possessing an effective maturity in 2035. Rather than holding every single security within the index, the Fund employs a "sampling" approach to meet its investment objectives. Both the fund's holdings and the index's composition undergo monthly adjustments. Designed with a specific expiration in mind, this fund is slated to liquidate its assets on or around December 15, 2035. For exhaustive details, please refer to the fund's official prospectus.
