Abstract:
We present novel multi-period portfolio selection models that incorporate Environmental, Social, and Governance (ESG) considerations into investment decisions. Although ESG investing has gained significant attention, most existing approaches rely on static models, which inadequately capture the dynamic nature of markets and evolving investment conditions. To address this limitation, we develop an ESG-adjusted multi-period mean-risk (ESG-MMR) portfolio optimization framework, specifically developing two variants: an ESG-adjusted multi-period mean-variance (ESG-MMV) model and a hybrid ESG-MMV-CVaR model that incorporates Conditional Value at Risk (CVaR) as a supplementary risk measure. For ESG-MMV model, we leverage the state separation theorem to derive a semi-analytical optimal portfolio policy, showing that the optimal strategy follows a piecewise affine function of wealth which can be efficiently computed by solving coupled equations offline. For ESG-MMV-CVaR model, we develop two Progressive Hedging Algorithm (PHA) variants-one guaranteeing theoretical convergence and the other prioritizing practical efficiency. Through numerical experiments, we demonstrate that our dynamic approaches significantly outperform static ESG portfolio models. Our framework is flexible and can accommodate various risk measures beyond variance and CVaR, offering practitioners an efficient toolkit for implementing ESG considerations in modern portfolio management.
