Bonds Aren't Equal: Why Some Fail to Protect Portfolios in Bear Markets
Why Bonds Don't Always Protect Portfolios

The Complex Reality of Bond Protection in Market Downturns

While bonds are traditionally viewed as essential portfolio stabilizers during equity bear markets, the reality is far more nuanced than many investors realize. According to investment expert Noah Solomon, the protective qualities of fixed-income assets vary dramatically depending on the specific bond type and market conditions.

The critical function of bonds lies in their ability to mitigate portfolio losses when stocks decline, but different bond portfolios deliver vastly different results. This complexity means investors cannot simply assume all bonds will provide adequate protection during market turbulence.

The Unavoidable Risk-Return Relationship in Fixed Income

Drawing on data from FactSet Research Systems covering 2000 to 2024, Solomon illustrates economist Milton Friedman's principle that there is no such thing as a free lunch in bond investing. The evidence clearly shows that risk and reward move together across fixed-income assets.

Treasury Bills delivered the lowest annualized return at 1.8% but experienced almost no peak-to-trough losses at just -0.4%. Short-term Treasuries showed similarly modest characteristics with 2.4% returns and -5.4% maximum losses.

Meanwhile, medium-term investment-grade corporate bonds and medium-term Treasuries demonstrated higher returns of 4.7% and 4.1% respectively, but both suffered significant peak-to-trough losses approaching -23%. Even more dramatically, long-term Treasuries provided 4.5% annualized returns but experienced staggering -47.6% losses at their worst point.

The highest-yielding segments revealed the same pattern: high-yield bonds delivered 4.9% returns with -30.3% losses, while emerging-market sovereign bonds offered the strongest returns at 6.7% but still suffered -26.8% drawdowns.

The Hidden Correlation Risk with Equities

Beyond the obvious risk-return trade-off, Solomon identifies another critical consideration: correlation to stock markets. Higher-returning bonds tend to move more in sync with equities, reducing their diversification benefits precisely when investors need protection most.

Treasury Bills showed minimal correlation to the S&P 500 at -9.1% while delivering those modest 1.8% returns. Short-term Treasuries demonstrated the most negative correlation at -19.9% with 2.4% returns.

However, corporate bonds told a different story. Short-term investment-grade corporates showed 31.3% correlation to equities with 4% returns, while medium-term investment-grade corporates reached 35.8% correlation alongside 4.7% returns.

This relationship means that investors seeking higher bond returns often sacrifice the very diversification that makes bonds valuable during stock market declines. The bonds that offer the best returns tend to behave more like equities, potentially failing to provide the cushion investors expect during bear markets.

For Canadian investors building resilient portfolios, understanding these nuances becomes crucial. The choice between different bond types involves balancing return objectives with the specific protection needed during potential market downturns, recognizing that higher returns come with both larger potential losses and reduced diversification benefits.
