Portfolio optimization with linear and fixed transaction costs
Investment transaction costs linear transactions
2015/8/10
We consider the problem of portfolio selection, with transaction costs and constraints on exposure to risk. Linear transaction costs, bounds on the variance of the return, and bounds on different shor...

With the development of supermarket chains in China, the competition intensified, logistics and distribution is gradually becoming a key factor of the competitive strength of the supermarket chains. T...
Optimization Method for Interval Portfolio Selection Based on Satisfaction Index of Interval inequality Relation
Interval portfolio selection satisfaction index semiabsolute deviation risk parametric linear programming
2012/9/14
In this paper we consider an interval portfolio selection problem with uncertain returns and introduce an inclusive concept of satisfaction index for interval inequality relatio...
Portfolio optimization with insider's initial information and counterparty risk
asymmetric information enlargement of filtrations counterparty risk optimal investment duality dynamic programming.
2012/9/14
We study the gain of an insider having private information which concerns the default risk of a counterparty. More precisely, the default time τ is modelled as the first time a stochastic process hits...
On the Equivalence of Quadratic Optimization Problems Commonly Used in Portfolio Theory
investment analysis mean-variance analysis parameter uncertainty interval estimation test theory.
2012/9/14
In the paper, we consider three quadratic optimization problems which are frequently applied in portfolio theory, i.e, the Markowitz mean-variance problem as well as the problems based on the mean-var...
We develop a new model of random choice to study violations of the weak axiom of
revealed preference. We introduce the notion of a stochastic preference and show that it
implies the Luce model. Our ...

Monte Carlo Portfolio Optimization for General Investor Risk-Return Objectives and Arbitrary Return Distributions: a Solution for Long-only Portfolios
Portfolio Optimization Optimisation Random Portfolio Monte Carlo Simplex
2010/10/21
We develop the idea of using Monte Carlo sampling of random portfolios to solve portfolio investment problems. In this first paper we explore the need for more general optimization tools, and conside...
Transversality Conditions for Higher Order Infinite Horizon Discrete Time Optimization Problems
Transversality condition Dynamic optimization
2010/10/20
In this paper, we examine higher order difference problems. Using the "squeezing" argument, we derive both Euler's condition and the transversality condition. In order to derive the two conditions, tw...
