A new diversification measure appears to produce better results than mean-variance optimisation
New diversification measure enables construction of equally diversified portfolios
In this paper the authors formulate a novel Markov regime-switching factor model to describe the cyclical nature of asset returns in modern financial markets.
In this paper, the author uses the mean–variance hedging criterion to value contracts in incomplete markets.
This paper is devoted to the question of optimal portfolio construction for equity factor investing. The authors discuss the question of multifactor portfolio construction and show that the simplistic approaches often used by practitioners tend to be…
Venturelli and Kondratyev use quantum annealers to optimise portfolios
This paper investigates the distributional characteristics of stock market returns and analyzes the significance of higher moments.
This paper examines how the Kelly criterion can be implemented into a portfolio optimization model that combines risk and return into a single objective function using a risk parameter.
This paper proposes a numerical optimization approach that can be used to solve portfolio selection problems including several assets and involving objective functions from cumulative prospect theory (CPT).
Quants propose technique to include stress testing in portfolio allocation
Yong (Jimmy) Jin and Lie Wang propose an estimation method for optimal portfolio weights under parameter uncertainty
The authors of this paper derive an optimal trading strategy that benchmarks the closing price in a mean–variance optimization framework.
Numerical solution of the Hamilton–Jacobi–Bellman formulation for continuous-time mean–variance asset allocation under stochastic volatility
The paper deals with robust and accurate numerical solution methods for the nonlinear Hamilton–Jacobi–Bellman partial differential equation (PDE), which describes the dynamic optimal portfolio selection problem.
Risk balancing has been considered a heuristic asset allocation method. In this paper, the authors show that, on the contrary, risk balancing is a special case of a utility optimization problem with log regularization that constrains risk concentration.
Nobel prize-winner defends his work on portfolio theory, which critics claim has been discredited by the crisis
