Three of the five largest bond ETFs by assets delivered negative returns over the past five years, a 3-of-5 record that places 60% of the market's largest funds in the red for the period. That figure has become the center of a growing debate among ETF investors: whether bonds still belong in a diversified portfolio. The funds were designed to smooth volatility. They have functioned closer to an anchor.
The conventional case for bond ETFs is cushion. Investors hold them to blunt the swings in equity-heavy allocations, accepting lower expected returns in exchange for stability. The 3-of-5 result at the top of the market by assets suggests that exchange has not held in the stretch now visible in performance histories. Funds built to absorb drawdowns have, in the recent period, generated them.
Sentiment is reflecting the record. The temptation to exit bond funds entirely has been building among ETF investors, and results in three of the five largest funds by assets give that impulse a factual basis. Whether the same outcome holds across the full bond ETF universe, or concentrates at the asset-weighted top, the available data covers only the five largest funds by assets.
