For investors looking to include some high-quality fixed income to their portfolios, funds like the Vanguard Short-Term Bond ETF (BSV), the Vanguard Total Bond Market ETF (BND), or the Vanguard Short-Term Inflation-Protected Securities ETF (VTIP) may be worth looking into. BSV seeks to track the performance of the Bloomberg U.S. 1–5 Year Government/Credit Float Adjusted Index, a market-weighted bond index that covers investment-grade bonds with a dollar-weighted average maturity of one to five years. BSV has an expense ratio of 0.04%.
