## What's inside

BSV tracks a broad short-term bond index with just 30 holdings, heavily weighted toward U.S. Treasury bonds, as reflected in its top positions in various Treasury note issues. This approach results in a large, highly liquid fund (19 years old; $70.0 billion assets under management) that focuses on government and high-quality corporate debt.

IGSB, by contrast, spreads its $21.9 billion assets under management across more than 4,500 bonds, all investment-grade corporates with maturities between one and five years. Its top holdings include Eagle Funding Luxco S. R.l. 144a, T-Mobile USA, and Goldman Sachs Group Inc, signaling a broader corporate credit exposure. Neither fund features unusual quirks or overlays.

## What this means for investors

Bonds are an important component for investment portfolios as they provide stability, regular income, and diversification while reducing overall portfolio risk. In considering the iShares 1-5 Year Investment Grade Corporate Bond ETF (IGSB) and Vanguard Short-Term Bond ETF (BSV), both are low cost but serve different roles.

BSV delivers higher safety by focusing on government bonds, and provides greater liquidity given its nearly $70 billion in assets under management. The trade off is that it offers a lower dividend yield and one-year return compared to IGSB.

IGSB comprises substantially more diversification with over 4,500 bonds, which includes corporate bond exposure. This contributes to the fund delivering stronger one-year performance and a higher yield, but with slightly greater risk and expense ratio.

Both BSV and IGSB are solid ETFs to add bonds to your portfolio, and the choice comes down to individual investor preference. If lower cost, higher liquidity, and greater safety and stability are the priority, then BSV is the superior ETF. IGSB is the better fund for those who seek higher income and stronger performance in exchange for more risk.
