HYG holds below-investment-grade US corporate bonds — debt issued by companies rated BB or lower that pay higher interest rates to compensate investors for meaningfully higher default risk. The yield of around 6.7% reflects that credit risk premium. High yield bonds behave more like equities than like investment grade bonds: they fall sharply during economic stress as default expectations rise, but they perform well during economic expansions when corporate credit quality is improving and refinancing conditions are favorable. Unlike investment grade bonds, high yield prices are driven more by credit spread movements — the extra yield over Treasuries — than by interest rate duration, which means HYG does not behave as a traditional interest rate hedge. Correlations with equity markets are high during risk-off periods. For investors, HYG provides an income-oriented middle ground between investment grade bonds and equities, with higher yield than either one but without the equity upside in bull markets. It is most useful for income-focused investors who accept credit risk in exchange for elevated yield, and requires awareness that in a real recession, high yield spreads can widen dramatically, producing losses that negate several years of income advantage.
