As part of Invesco's BulletShares investment-grade suite, BSCO behaves more like a bond than a typical bond fund. The fund provides bullet maturity (Dec. 31, 2024) instead of perpetual exposure to a maturity pocket of the US corporate investment-grade market. As the fund ages, its average maturity, duration, and YTM will continue to decline. On its target date, BSCO will unwind and return all capital to investors. This structure permits BSCO to be used as a building block for a bond ladder. The fund charges a reasonable fee, though loose tracking has sometimes translated to higher realized holding costs. In all, the fund provides a viable means to access a diverse pool of US investment-grade bonds while mimicking the lifecycle of an individual bond. BSCO hews close to marketlike exposure.
