The Prudential Short Duration High Yield Fund, Inc. operates as a closed-end mutual fund specializing in fixed income. Established and managed by Prudential Investments LLC, with Prudential Investment Management, Inc. acting as co-manager, this U.S.-based fund began operations on April 30, 2012. Its primary focus is on the American fixed income markets, where it builds a diversified portfolio. The fund specifically targets high-yield fixed income instruments that are rated below investment grade—meaning Ba1 or lower by Moody's Investors Service, Inc., or BB+ or lower by Standard & Poor's Ratings Services. While it considers debt securities of all maturities, a key objective is to keep the portfolio's weighted average duration at three years or less. Investment decisions are guided by fundamental analysis. Notably, the fund explicitly excludes municipal debt obligations, asset-backed securities, and mortgage-backed securities from its holdings.
