Scalable Pontryagin-Guided Adjoint-to-Control Recovery for Constrained Dynamic Portfolio Choice

Jaegi Jeon, Jeonggyu Huh, Hyeng Keun Koo +1

We study continuous-time multi-asset portfolio choice and consumption under smooth pointwise constraints, including state-dependent feasible sets. The method separates dynamic info…

Breaking the Dimensional Barrier: A Pontryagin-Guided Direct Policy Optimization for Continuous-Time Multi-Asset Portfolio Choice

Jeonggyu Huh, Jaegi Jeon, Hyeng Keun Koo +1

We introduce the Pontryagin-Guided Direct Policy Optimization (PG-DPO) framework for high-dimensional continuous-time portfolio choice. Our approach combines Pontryagin's Maximum P…

Breaking the Dimensional Barrier for Constrained Dynamic Portfolio Choice

Jeonggyu Huh, Jaegi Jeon, Hyeng Keun Koo +1

We propose a scalable, policy-centric framework for continuous-time multi-asset portfolio-consumption optimization under inequality constraints. Our method integrates neural polici…

Extensive networks would eliminate the demand for pricing formulas

Jaegi Jeon, Kyunghyun Park, Jeonggyu Huh

In this study, we generate a large number of implied volatilities for the Stochastic Alpha Beta Rho (SABR) model using a graphics processing unit (GPU) based simulation and enable…

Consistent and Efficient Pricing of SPX and VIX Options under Multiscale Stochastic Volatility

Jaegi Jeon, Geonwoo Kim, Jeonggyu Huh

This study provides a consistent and efficient pricing method for both Standard & Poor's 500 Index (SPX) options and the Chicago Board Options Exchange's Volatility Index (VIX) opt…
