Unleveraged Portfolios and Pure Allocation Return

Risk-Based Allocation of Principal Portfolios

Risk-based asset allocation strategies are mainly used to diversify nominal asset weights. In this paper, we discuss the diversification of risk factors. The analysis is based on the idea of Partovi and Caputo (2004), who use principal component analysis to transform a portfolio into a set of uncorrelated principal portfolios. Risk-based asset allocation strategies can be applied to these uncor...

Optimal Guaranteed Return Portfolios and the Casino Effect

In this paper, we address the problem of maximizing expected return subject to a worst case return constraint by composing a portfolio that may consist of cash, holdings in a stock market index and options on the index. We derive properties of optimal and feasible portfolios and present a linear programming model to solve the problem. The optimal portfolios have pay-off functions that reflect a...

Strategic Allocation to Return Factors

A new methodology for deriving the efficient frontier of stocks portfolios: An advanced risk-return model

In this paper after a general literature review on the concept of Efficient Frontier (EF), an important inadequacy of the Variance based models for deriving EFs and the high necessity for applying another risk measure is exemplified. In this regard for this study the risk measure of Lower Partial Moment of the first order is decided to replace Variance. Because of the particular shape of the pr...

Dynamic Allocation of Treasury and Corporate Bond Portfolios

In this paper, we solve the intertemporal investment problem of an investor holding a portfolio of default-free and defaultable bonds. Default-risk is modeled in an intensity based framework with state variables following an a¢ne di¤usion. The structure of the optimal portfolio over time is investigated and compared to the static meanvariance portfolio. Furthermore, we describe the impact of ti...
