Corrects a flawed claim in decentralized finance, but the result is incremental as it only refutes a specific mechanism.
The paper disproves claims that Target Weight Mechanism (TWM) reduces delta in Perpetual Demand Lending Pools, proving the condition is self-contradictory and that no TWM can uniformly lower delta.
Chitra et al. (2025) claim that Target Weight Mechanism (TWM) in Perpetual Demand Lending Pools (PDLPs) can lower the delta of the portfolio under certain condition. We prove that their condition is self-contradictory. Furthermore, we prove an impossibility result that no TWM can lower the delta uniformly.
