Exponential investors with weakly mean-reverting prices

Battle Count: 53

Highly relevant for understanding the theoretical limits of trading strategies in mean-reverting markets. It provides explicit asymptotic growth rates and optimal strategy structures for investors with exponential utility, which is a standard assumption in quantitative finance.

Implementing the theoretical strategy requires handling smoothed power functions and ensuring C2 continuity, which is more complex than standard linear mean-reversion strategies. However, the asymptotic nature suggests it is primarily for theoretical benchmarking or long-horizon strategy design.

The paper provides full mathematical derivations, explicit formulas for the optimal strategy, and clear definitions of the model parameters. However, it is a theoretical paper without empirical data or code repositories, so reproducibility relies on verifying the mathematical proofs.
