Corporate bond ETF comparison

What happened: In a comparison of corporate bond ETFs, iShares' IGSB delivered a higher 1-year total return and yield than Vanguard's BSV, despite BSV having three times the assets under management. Meanwhile, iShares' IGIB offered broader bond diversification than Fidelity's FIGB, while FIGB had a heavier cash and Treasury focus. Additionally, Vanguard's BSV was less expensive to own and managed much more in assets than iShares' ISTB, but ISTB delivered a higher 1-year return and slightly higher yield.

Market impact: These comparisons highlight the trade-offs between yield, diversification, fees, and asset size among corporate bond ETFs. Investors seeking higher yields or broader diversification may prefer IGSB or IGIB, while those prioritizing lower costs and larger scale might choose BSV.

What to watch next: Investors should monitor the 1-year total returns and yields of these ETFs to see if the current trends continue. Additionally, they should keep an eye on the performance of the underlying bonds in each ETF's portfolio, as changes in interest rates and credit spreads could impact returns. Lastly, any changes in the funds' asset under management could signal shifts in investor sentiment or preferences.
