PTRB offers a diversified, global fixed income exposure. The actively managed portfolio consists of investment-grade and high-yield government debt obligations, mortgage- and asset-backed securities, and corporate debt, each having a maturity of greater than a year. Constituents are selected using a combination of top-down economic analysis (economic, policy and market trends) and bottom-up research (issuers financial health), along with proprietary quantitative models and risk management factors. In addition, investment factors such as expected total return, yield, spread, and potential for price appreciation are also considered. The fund may invest up to 30% of its net assets in foreign debt securities. Same threshold applies with high-yield securities or junk bonds. PTRB is the ETF version of the mutual fund, PGIM Total Return Bond Fund.
