Explanation:
The critical drawback of a DV01-neutral hedge is its assumption that yield changes across different maturities are parallel. This means that the hedge will not be accurate if the yield curve experiences a non-parallel shift, which is common in real markets due to a variety of economic factors that can affect short-, medium-, and long-term interest rates differently. This lack of flexibility in responding to real-world yield curve changes can make the DV01-neutral strategy less effective in practice.
A is incorrect. In reality, DV01-neutral hedges are ill-suited to address non-parallel shifts, detracting from the statement's accuracy.
B is incorrect. Credit spreads remain a significant risk factor that DV01-neutral hedging strategies do not cover.
D is incorrect. The effectiveness of DV01-neutral hedging is compromised by static assumptions on historical correlations.

Q.6502 A large investment fund has been utilizing a DV01-neutral hedge strategy to manage its vast bond portfolio's interest rate exposure. Over time, market dynamics have shown this approach's limited realism. What is a critical drawback of relying on a DV01-neutral hedge in today's complex yield environment?
A
It captures non-parallel yield curve shifts across multiple bond maturities.
B
The strategy inherently assumes that all spread-related risks are neutralized.
C
It assumes yield changes are parallel across maturities, which is rarely the case.
D
The accuracy of the hedge greatly improves with non-static historical correlations.
