SPMB is a passively managed exchange-traded fund that invests at least 80% of its total assets in securities that replicate or closely match its underlying benchmark index. The index tracks the U.S. agency mortgage pass-through segment of the U.S. investment-grade bond market, meaning the funds holdings are primarily mortgage-backed securities issued or guaranteed by U.S. government agencies and government-sponsored enterprises such as Fannie Mae, Freddie Mac, and Ginnie Mae. By pooling residential home loans and passing through the principal and interest payments to investors, these securities provide bondholders with exposure to the U.S. housing market while carrying the implicit or explicit credit backing of the federal government or its affiliated entities.
Launched in January 2009 and managed under the SPDR Portfolio series, SPMB is designed to deliver broad, low-cost access to the government mortgage-backed bond category, making it a core fixed-income building block for investors seeking duration and yield tied to U.S. housing credit.
