It’s been a tumultuous period for corporate bond ETFs investors, especially with a wave of defaults and downgrades expected due to the impacts of the Covid-19 pandemic. But some funds have exceeded their peers in their ability to offer durable long-term returns.

The top 10 ETFs in the combined corporate bond and high-yield bond categories represent a diverse cross section of funds, acccording to Morningstar data. But only two true high-yield ETFs returned enough to make our list. Other high performers were found among the “fallen angel” bond ETFs that target issuers who were recently downgraded to high-yield status.

Out of the 48 ETFs listed in Morningstar’s investment grade and high-yield corporate bond categories, many of those near the top of the list by three-year returns are among the lowest-cost passive funds available to investors.

Four of the top five ETFs by three-year performance are sponsored by BlackRock’s iShares ETF division.

These are Morningstar’s top 10 corporate bond ETFs by three-year return as of the market’s close on Dec. 1:

An investment-grade bond ETF, the $1.1 billion FLCO returned 6.89% over the past three years and 9.13% year to date. The ETF carries a 0.35% expense ratio.
