Robust portfolio selection with polyhedral ambiguous inputs
Ambiguity in the inputs of the models is typical especially in portfolio selection problem where the true distribution of random variables is usually unknown. Here we use robust optimization approach to address the ambiguity in conditional-value-at-risk minimization model. We obtain explicit models of the robust conditional-value-at-risk minimization for polyhedral and correlated polyhedral am...
متن کاملRobust preferences and robust portfolio choice
Financial markets offer a variety of financial positions. The net result of such a position at the end of the trading period is uncertain, and it may thus be viewed as a real-valued function X on the set of possible scenarios. The problem of portfolio choice consists in choosing, among all the available positions, a position which is affordable given the investor’s wealth w, and which is optima...
متن کاملportfolio selection by robust optimization
this paper discusses the portfolio selection based on robust optimization. since the parameters values of the portfolio optimization problem such as price of the stock, dividends, returns, etc. of per share are unknown, variable and their distributions are uncertain because of the market and price volatility, therefore, there is a need for the development and application of methodologies for de...
متن کاملRobust Portfolio Selection Problems
In this paper we show how to formulate and solve robust portfolio selection problems. The objective of these robust formulations is to systematically combat the sensitivity of the optimal portfolio to statistical and modeling errors in the estimates of the relevant market parameters. We introduce “uncertainty structures” for the market parameters and show that the robust portfolio selection pro...
متن کاملPortfolio selection under distributional uncertainty: A relative robust CVaR approach
Robust optimization, one of the most popular topics in the field of optimization and control since the late 1990s, deals with an optimization problem involving uncertain parameters. In this paper, we consider the relative robust conditional value-at-risk portfolio selection problem where the underlying probability distribution of portfolio return is only known to belong to a certain set. Our ap...
