C000262359 Investment Objective and Strategy
iShares Mortgage-Backed Securities Active ETF describes its objective and strategy as follows, from its latest prospectus filed with the SEC by BlackRock ETF Trust II.
Investment objective
The investment objective of iShares Mortgage-Backed Securities Active ETF (the “Fund”) is to seek to maximize total return, consistent with income generation and prudent investment management.
Principal investment strategy
Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in mortgage-backed securities (“MBS”) and derivatives that provide investment exposure to such securities or to one or more market risk factors associated with such securities. Such securities include, but are not limited to, securities issued by Government National Mortgage Association (“GNMA”), Federal National Mortgage Association (“Fannie Mae”) and Federal Home Loan Mortgage Corporation (“Freddie Mac”) as well as other U.S. Government securities. The Fund may participate in to be announced (“TBA”) transactions. A TBA transaction is a method of trading MBS where the buyer and seller agree upon general trade parameters such as agency, settlement date, par amount and price at the time the contract is entered into but the MBS are delivered in the future, generally 30 days later.
The actual pools of MBS delivered in a TBA transaction typically are not determined until two days prior to settlement date. The Fund measures its performance against the Bloomberg U.S. MBS Index (the “Benchmark”). Under normal circumstances, the Fund seeks to maintain an average portfolio duration that is within ±1 year of the duration of the Benchmark. The Fund makes investments in residential and commercial MBS as well as other asset backed securities. The Fund may buy or sell options or futures on a security or an index of securities, or enter into credit default swaps and interest rate transactions, including swaps (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls).
The Fund typically uses derivatives as a substitute for taking a position in the underlying asset and/or as part of a strategy designed to reduce exposure to other ris
