Nonmyopic Optimal Portfolios in Viable Markets

We provide a representation for the nonmyopic optimal portfolio of an agent consuming only at the terminal horizon when the single state variable follows a general diffusion process and the market consists of one risky asset and a risk-free asset. The key term of our representation is a new object that we call the “rate of macroeconomic fluctuation” whose properties are fundamental for the portfolio dynamics. We show that, under natural cyclicality conditions, (i) the agent’s hedging demand is positive (negative) when the product of his prudence and risk tolerance is below (above) 2 and (ii) the portfolio weights decrease in risk aversion.

About EDHEC-Risk Climate Impact Institute

Marking the priority assigned by the School to sustainability issues and building on its research programmes exploring the relationships between climate change and finance, EDHEC-Risk Institute became EDHEC-Risk Climate Impact Institute in October 2022. The Institute's mission is to help private and public decision-makers manage climate-related financial risks and make the best use of the financial tools available to transition to low-emission and climate-resilient economies.
