The Dimensional Ultrashort Fixed Income ETF (DUSB) seeks to provide current income while preserving capital through investment in high-quality, short-duration fixed income securities. This ultrashort-term bond ETF focuses on securities with maturities typically under one year, including Treasury bills, commercial paper, and high-grade corporate debt.
How It Works
DUSB employs an actively managed approach using Dimensional's proprietary research to select short-duration fixed income securities based on credit quality, liquidity, and yield optimization. The fund maintains an average duration of less than one year to minimize interest rate sensitivity while maximizing income potential. Portfolio managers continuously evaluate market conditions and adjust holdings to capture yield opportunities while maintaining capital preservation as the primary objective.
