The Invesco BulletShares 2028 High Yield Corporate Bond ETF (BSJS) is designed to mirror the performance of its underlying benchmark, the Invesco BulletShares High Yield Corporate Bond 2028 Index. The fund allocates a substantial portion of its assets, at least 80%, to corporate bonds included in this index. This index is constructed to track the returns of a portfolio consisting of high-yield corporate debt, issued in US dollars, all of which are scheduled to mature in 2028. Rather than purchasing every security in the index, the fund utilizes a "sampling" approach to achieve its investment goals. Both the fund's holdings and the index itself are rebalanced on a monthly basis. A key characteristic of this fund is its defined lifespan; it is structured to terminate on or about December 15, 2028, aligning with its 2028 maturity year. For comprehensive details, please consult the prospectus. Furthermore, investors should be aware that effective January 1, 2024, the benchmark index's name changed from the Nasdaq BulletShares USD High Yield Corporate Bond 2028 Index to its current title, the Invesco BulletShares High Yield Corporate Bond 2028 Index. Additional information can be found in the prospectus.
