This is an actively managed bond ETF that specializes in agency MBS, a core asset of the US mortgage market. Rather than simply tracking an index, it actively manages prepayment risk as interest rate conditions change, aiming for stable income and capital gains.

It suits investors who prefer the stability of high-quality bonds guaranteed by the US government, yet want additional returns driven by the skill of a professional manager.

It is an actively managed ETF launched in 2024 by a PIMCO-affiliated asset manager.

Within the agency MBS sector, the fund selects securities with superior relative value and uses strategies such as mortgage "dollar rolls" to improve management efficiency. It seeks to maximize portfolio performance by adjusting duration in response to interest rate changes and forecasting prepayment speeds.

• Leverages PIMCO's leading mortgage management expertise
• Active management of prepayment risk

Assets under management (AUM) stand at $1.4B, and the expense ratio is 0.71% per year.

The cost burden of active management is higher than that of passive products, but given the complexity of the mortgage market, this is a structure in which a manager's expertise can add value.

In periods of rising interest rate volatility, the relative price appeal of mortgage bonds has come into focus, and the fund strives to maintain steady performance on the strength of the high credit quality of agency MBS.

Interest continues from investors who want both a preference for safe assets and a stable income stream, and in particular, there is demand to adjust agency MBS weightings during sector rotation within the bond market.

Its strengths are the high credit quality of bonds issued by government-guaranteed agencies and active management, while prepayment risk when interest rates move is a weakness.

The MBB, VMBS, and SPMB shown in the table are representative low-cost passive ETFs in the agency MBS market, while JMTG and JMBS are competing products that select securities actively. If you want to earn the market average return at a lower cost, MBB is efficient, and PMBS can be a useful option when you want to combine it with PIMCO's other bond strategies or adjust interest rate sensitivity.

Here are the points to review before investing in PMBS. Although this product invests in high-quality assets, investors should fully understand the interest rate environment and the complexity unique to the mortgage market.

Even for government-guaranteed assets, investors should keep in mind the basic nature of bonds: asset values can fall and principal losses can occur during sharp rises in market interest rates.

It is a premium active bond solution suited to investors who want to secure stable income and excess returns in the US mortgage market through professional management expertise.
