The limitation of relying on static historical correlations between bond yields is critical. DV01-neutral hedging strategy relies on the assumption that historical correlations will remain stable, a condition that may not persist under changing economic or market scenarios. When correlations shift, the hedge may not perform as expected, leaving the position exposed to underhedging or overhedging risks.

A is incorrect. While liquidity differences can indeed influence the costs and feasibility of implementing a hedge, this limitation is not inherent to the DV01-neutral approach itself. DV01 measures price sensitivity to interest rate changes, and its scope does not include liquidity-related considerations.

C is incorrect. The approach does not incorporate convexity adjustments, which require consideration of more nuanced yield curve behaviors.

D is incorrect. While some hedges are complex, DV01-neutral hedging is not inherently complex and does not require advanced derivative strategies.

Things to Remember:

• Historical correlations can shift, presenting unanticipated hedge performance risks.
• Dynamic assessments of correlation are vital in adapting hedge strategies to real market conditions.
• Incorporating cross-market analysis can improve hedge effectiveness beyond DV01’s scope.
