A bullet bond portfolio can have an advantage over a barbell bond portfolio because:

Bullet Bond Portfolio

Invests in bonds with maturities focused on a single date or time period (a "bullet").

This structure eliminates the need for frequent adjustments as maturities naturally align with portfolio objectives.

Barbell Bond Portfolio

Invests in bonds with very short and very long maturities.

Requires regular rebalancing to maintain the intended allocation, increasing transaction costs.

Why the Answer is D

A bullet portfolio simplifies management by focusing on a single maturity period, avoiding the complexity of rebalancing inherent in barbell strategies.
