Bond Fund
A mutual fund or ETF that pools investor capital to purchase a diversified portfolio of bonds, providing fixed-income exposure to retail investors.
What is Bond Fund?
A bond fund is a pooled investment vehicle—structured as a mutual fund or ETF—that collects capital from multiple investors to purchase a diversified portfolio of fixed-income securities. Bond funds differ from individual bonds in that they have no fixed maturity date (the fund manager continuously buys and sells bonds), they distribute income monthly, and their NAV fluctuates daily with interest rates and credit conditions. Bond funds are classified by type (government, corporate, high-yield, municipal, international), maturity (short, intermediate, long), and geography. They provide retail investors access to bond diversification that would require millions of dollars to replicate individually.
Example
The Vanguard Total Bond Market Index Fund (VBTLX) tracks the Bloomberg U.S. Aggregate Bond Index, holding over 10,000 investment-grade bonds including Treasuries, agency bonds, and corporate bonds. With an expense ratio of 0.05%, it provides comprehensive U.S. bond market exposure for investors making monthly retirement account contributions who lack the capital to diversify across individual bonds.
