Volatility and Macroeconomic Dynamics

Volatility in high-yield markets has stabilized in 2025, with standard deviations hovering just over six—a far cry from the 65 recorded during the height of the pandemicThink That High Yield Bonds Are Risky? Think Again^[5]. This normalization reflects improved corporate fundamentals and a low-risk-of-recession environment. However, dispersion in credit performance remains high, with 64% of U.S. and 71% of European high-yield bonds trading outside the +/- 100 basis point range of the index levelHigh Yield Outlook: Elevated Yields Endure into 2025^[6]. Such dispersion underscores the need for active management to capture alpha while avoiding weaker issuers.

HYDB's lower volatility (5.96%) compared to equities and other high-yield ETFs like the iShares BB Rated Corporate Bond ETF (HYBB, Sharpe ratio of 1.22RSEE vs. HYDB — ETF Comparison Tool^[2]) further cements its role in portfolio efficiency. By reducing exposure to extreme price swings, HYDB enables investors to maintain a balanced allocation without sacrificing yield.
