iShares Mortgage-Backed Securities Active ETF (MBBA)

The iShares Mortgage-Backed Securities Active ETF is an actively managed fixed income fund sponsored by BlackRock under its iShares brand. Its objective is to generate total return, combining income and capital appreciation, primarily through investments in mortgage-backed securities.

The portfolio focuses mainly on agency mortgage pass-through securities issued or guaranteed by Ginnie Mae, Fannie Mae and Freddie Mac, and it may also use to-be-announced (TBA) transactions and related instruments. BlackRock's portfolio managers make security selection, coupon and duration decisions rather than replicating an index, aiming to add value relative to the broad U.S. mortgage-backed securities market.
