MBB Fund Description

The iShares MBS ETF tracks a market-weighted index of investment-grade mortgage pass-through securities. The index includes fixed and floating rate securities issued by GNMA, FNMA and FHLMC.

MBB Factset Analytics Insight

For pure-play coverage of mortgage pass-through debt issued by the major US agencies, MBB brings the total package. The fund offers excellent coverage; but to be fair, so do two competing funds—VMBS and MBG—that track the same or similar indexes. AUM and liquidity give MBB the edge over these peers. The fund was first to market in this space in 2007, and has a hefty asset base to show for it. It trades well too. MBB is competitively priced after iShares slashed the fund’s fee in July 2017. Excellent tracking means that true holding costs are in line with that low fee. (Our reported tracking statistics will partly reflect the fund’s old expense ratio for up to 2 years). In all, MBB is a solid choice for MBS exposure, and it earns our Analyst Pick for the segment.
