   Insights on Time-consistent Deep Hedging under Elicitable Dynamic Risk Measures

   Shuyi Zhang, Frédéric Godin · ARXIV

   quant relevance 0.97

   The paper develops a reinforcement-learning method for daily dynamic hedging of a high-dimensional basket option under time-consistent conditional CVaR objectives. Its numerical results are based on a simulated DCC-GARCH environment rather than a measured real-market trading backtest, but the hedging method can be tested on historical US-equity baskets with synthetic option liabilities.

   Eliciting ESG Preferences for Reinforcement Learning-Based Portfolio Optimization

   Giovanni Dispoto, Marcello Restelli, Carmine Ventre · ARXIV

   quant relevance 0.96

   The paper proposes daily ESG-aware portfolio optimization using a preference-conditioned PPO policy, with Sharpe ratio and three agency-specific ESG scores as objectives. A Gaussian-process preference-elicitation layer infers portfolio-manager objective weights from pairwise portfolio choices, evaluated using LLM personas under regional prompts. It is directly relevant to systematic portfolio construction, but the required multi-provider ESG data are not available.

   Price manipulation in nonlinear transient impact models: rigidity before memory and complete positivity after memory

   Minhyeok Lee · ARXIV

   quant relevance 0.96

   This is a theoretical market-microstructure and optimal-execution paper characterizing when nonlinear transient price-impact models permit profitable round-trip manipulation. Its central practical implication is model selection for execution-cost estimation and algorithmic trade scheduling: concave impact should be applied after resilient memory rather than directly to trading rate unless sufficient friction is included.
