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...
Multi-period portfolio optimization with constraints and transaction costs
Investment combinatorial optimization the horizon assets minimum deviation standard dynamic
2015/8/10
We consider the problem of multi-period portfolio optimization over a finite horizon, with a self-financing budget constraint and arbitrary distribution of asset returns, with objective to minimize th...

Robust portfolio optimization using pseudodistances
Robustness and sensitivity analysis portfolio optimization
2013/6/14
The presence of outliers in financial asset returns is a frequently occuring phenomenon and may lead to unreliable mean-variance optimized portfolios. This fact is due to the unbounded influence that ...
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...
Belief Propagation Algorithm for Portfolio Optimization Problems
Belief Propagation Algorithm Portfolio Optimization Problems
2010/10/21
The typical behavior of optimal solutions to portfolio optimization problems with absolute deviation and expected shortfall models using replica analysis was pioneeringly estimated by S. Ciliberti and...
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...
When do improved covariance matrix estimators enhance portfolio optimization? An empirical comparative study of nine estimators
covariance matrix nine estimators portfolio optimization
2010/4/28
The use of improved covariance matrix estimators as an alternative to the sample estimator is considered an important approach for enhancing portfolio optimization. Here we empirically compare the per...
Portfolio optimization in a defaults model under full/partial information
Optimal investment default time default intensity,filtering dynamic program-ming principle
2010/4/27
In this paper, we consider a financial market with assets exposed to some risks inducing jumps in the asset prices, and which can still be traded after default times. We use a default-intensity modeli...
