In this paper we present an application where advanced undergraduate students can solve the expected utility portfolio model with a risk-free and a risky asset with both up and down returns in the Stock Market. With real Stock Market data, we use Excel Solver to find the portfolio decision and...

This paper points out to loopholes in Modern Portfolio Theory (MPT) and fundamental flaws that question its validity and applicability not only for investment but for education as well. Using theoretical analysis, Monte Carlo simulations and market data I present and discuss theoretical, as well...

The purpose of this case is to provide an introduction to fixed income portfolio management. In addition, the case describes the story of Bill Gross and the founding of PIMCO.Bill Gross continues to work the same schedule since joining PIMCO in 1970; a rigorous and structured workday that begins at...

Accepted wisdom, assuming capital market equilibrium and low cash returns, advises investors to hold optimal portfolios containing little cash. But credit crunches - periods of non-price credit rationing when effective cash yields are very high - happen in the real world. Because of this, it is...

This paper constructs an alternative investment strategy to portfolio optimization model in the framework of the Mean–Variance portfolio selection model. To differentiate it from the ubiquitously applied Mean–Variance model, which is constructed on an assumption that returns are normally...

In this working paper we study some properties of a particular mapping in Rn related to an optimization problem with one equality constraint. We motivate the definition of the relevant mapping starting from a portfolio selection problem, in which we minimize the risk of an investment (the...

As the skewed return distribution is a prominent feature in nonlinear portfolio selection problems which involve derivative assets with nonlinear payoff structures, Value-at-Risk (VaR) is particularly suitable to serve as a risk measure in nonlinear portfolio selection. Unfortunately, the...

In spite of their importance, third or higher moments of portfolio returns are often neglected in portfolio construction problems due to the computational difficulties associated with them. In this paper, we propose a new robust mean–variance approach that can control portfolio skewness and...

An essential element of any realistic investment portfolio selection is the consideration of transaction costs. Our purpose, in this paper, is to determine the maximum return and the corresponding number of securities to buy giving such return, whenever practical constraints features related to...

This paper discusses a multi-objective portfolio optimization problem for practical portfolio selection in fuzzy environment, in which the return rates and the turnover rates are characterized by fuzzy variables. Based on the possibility theory, fuzzy return and liquidity are quantified by...
