Rebalancing-versus-Rebalancing: Improving the fidelity of Loss-versus-Rebalancing

This presentation examines a breakthrough in measuring automated market maker performance for liquidity providers. The research introduces Rebalancing-versus-Rebalancing (RVR), a new metric that accounts for real-world frictions in centralized exchanges, revealing that AMM pools can outperform traditional rebalancing strategies. Through extensive simulations testing over 1000 strategy configurations across 3.5 years of market data, the work demonstrates how dynamic AMMs using Temporal Function Market Makers create opportunities for more efficient decentralized asset management.

Most benchmarks for automated market makers rely on an impossible standard: perfect, frictionless rebalancing that doesn't exist in the real world. This paper introduces a metric that actually accounts for the costs and constraints real traders face.
The existing metric, Loss-versus-rebalancing, measures AMM performance against a benchmark that assumes you can rebalance your portfolio instantly without any fees. That's like judging a car's fuel efficiency assuming perfectly smooth roads with no traffic.
The authors propose a fundamentally different approach.
Rebalancing-versus-Rebalancing changes the comparison entirely. Instead of measuring against an impossible ideal, it compares AMM performance against what you'd actually pay to rebalance on centralized exchanges like Binance, including all the messy real-world costs.
The key innovation is using Temporal Function Market Makers. These dynamic AMMs store weight trajectories on-chain and update pricing based on strategy signals. When prices deviate from the target, arbitrageurs naturally rebalance the pool by exploiting the price difference.
The mechanism is elegant. The pool calculates desired weights using price oracles and stores them on the blockchain. Arbitrageurs monitor for discrepancies between the pool's current state and its target weights, then profit by executing the rebalancing trades the strategy needs.
The findings challenge conventional wisdom about decentralized trading.
Across 1000 strategy configurations tested on Binance market data from 2021 to 2024, the results are striking. AMM pools actually deliver better execution than centralized rebalancing except when exchange fees drop to unrealistically low levels. This fundamentally validates the potential for decentralized asset management.
This research gives asset managers a realistic framework for evaluating AMM strategies. The authors conservatively excluded retail fee income in their models, meaning actual AMM performance could be even better. Future work might optimize how weight trajectories adapt to changing market conditions.
By replacing an impossible benchmark with a realistic one, this work reveals that decentralized markets can compete with and even surpass centralized execution. Visit EmergentMind.com to explore more research and create your own video presentations.
