Vanguard Intermediate-Term Bond Index Fund Admiral Shares and Vanguard Intermediate-Term Bond ETF side by side. VBILX and BIV are share classes of one fund, Vanguard Intermediate-Term Bond Index Fund: one portfolio, filed with the SEC as one, so the holdings, overlap and flows below are the fund's, the same for both. What differs is the fee, how each is bought (a mutual fund once a day at its closing price, an ETF on an exchange through the day) and the small gap in returns that follows. BIV is the cheaper fund (0.04% vs 0.06% expense ratio). Over the last five years BIV returned more (+0.33% vs +0.32%, total return). Their portfolios overlap by about 100% of weight.

All returns are total returns (dividends reinvested), through the latest price during the session. CAGR = compound annual growth rate. '—' means the fund's history doesn't span the horizon. A mutual fund's AUM is its whole fund's, every share class together (its SEC filing); an ETF's is its own. Returns run to Oct 30, 2026, the last month-end, as fund companies report a mutual fund's: a fund that pays monthly books each month's income on its last business day, so a return to a later day would leave that month's income out.

Methodology#

Returns are total returns (dividends reinvested) from daily adjusted closes. Holdings, overlap, sector weights and flows derive from each fund's public SEC filings (Form N-PORT), anchored on the latest filing and rolled forward daily by price moves. Overlap is the sum of the smaller weight across shared holdings. See each fund's full holdings: VBILX holdings · BIV holdings. Past performance does not predict future returns; not investment advice.
