About VBTIX

Vanguard Total Bond Market Index Fund Institutional Shares is an open-end mutual fund focused on providing broad exposure to the U.S. investment-grade fixed income market. Its primary objective is to track the performance of the Bloomberg US Aggregate Float Adjusted Index, a widely followed benchmark representing a comprehensive cross-section of investment-grade, fixed-rate, taxable bonds denominated in U.S. dollars. The fund holds a diversified mix of U.S. Treasury securities, government agency debt, corporate bonds, as well as mortgage-backed and asset-backed securities, resulting in a portfolio that is heavily weighted toward U.S. Treasuries—typically around 40%-50% of assets—which supports its conservative credit risk profile and high average credit quality. Managed with a focus on minimizing fees, the fund offers an exceptionally low expense ratio, making it cost-effective for large institutional investors. Its low turnover and market value-weighted approach help ensure consistent, representative exposure to the U.S. bond market. Vanguard Total Bond Market Index Fund Institutional Shares plays a significant role in institutional portfolios and retirement plans, serving as a core fixed income holding intended to deliver steady income and help buffer portfolio volatility during periods of market stress.
