High Dimensional Portfolio Selection with Cardinality Constraints

Overview

High-Dimensional Portfolio Selecton with Cardinality Constraints

This repo contains code for perform proximal gradient descent to solve sample average approximation of expected utility maximization problems with cardinality constraints. We show that, under mild conditions, the $l_1$-regularized problem is equivalent to the $l_0$-constrained problem.

Requirements

We use Python 3 for our code. Please refer to requirements.txt, and use pip or conda to create a virtual environment with required packages installed.
