There's a lot to like about market-cap-weighted bond index funds. They offer low fees, a consistent and transparent approach with no key-manager risk, and low transaction costs because they favor the most-liquid issues and have fairly low turnover. But market-cap weighting may not be the optimal way to construct a bond portfolio because it tilts toward the most heavily indebted issuers. The implications of this are different in the investment-grade and high-yield market segments. In the investment-grade market, cap-weighting skews most portfolios toward low-yielding Treasuries and agency mortgage-backed securities, dragging down expected returns. In the high-yield market, the biggest debtors may have particularly high credit risk.
