VMBS

The Vanguard Mortgage‑Backed Securities Index Fund ETF (VMBS) invests primarily in U.S. agency mortgage‑backed pass‑through securities issued by Ginnie Mae, Fannie Mae and Freddie Mac, providing exposure to the domestic mortgage‑backed securities market. It follows a passive, index‑sampling approach that seeks to track the Bloomberg U.S. MBS Float Adjusted Index, holding a diversified set of intermediate‑term agency MBS that meet the index’s size and maturity criteria. Because the holdings are government‑sponsored and carry high credit quality, the fund delivers current income with relatively low credit risk but retains interest‑rate and prepayment sensitivity. VMBS is suitable for investors looking to add mortgage‑backed securities exposure for income and diversification within a broader fixed‑income portfolio, particularly those comfortable with moderate duration risk.
