Portfolio management starts with asset allocation. There is a consensus that asset allocation plays an important role in determining portfolio performance (Arshanapalli, Coggin & Nelson, 2001). Active portfolio management implies the rebalancing of the existing portfolio by buying and selling assets. The aim of rebalancing is to improve the performance of the managed portfolio by adjusting it t...

This paper gives a full and detailed account of the design and development of a web-based learning portfolio (WBLP) system for authentic assessment, in the hope to help record, display, and monitor student learning process. The functions of the WBLP system include portfolio creation, portfolio browse, portfolio guide, portfolio discussion board, portfolio class bulletin, suggestion board, stude...

In this paper, we develop a dynamic investment model maximizing the expected “utility” of excess return relative to a benchmark portfolio. Following the standard setting of continuous time framework for the securities market developed by Merton (1971) and others, we obtain an explicit formula for the optimal portfolio policy for a utility function ofHyperbolic Absolute Risk Aversion (HARA). Unl...

Many portfolio optimization problems deal with allocation of assets which carry a relatively high market price. Therefore, it is necessary to determine the integer value of assets when we deal with portfolio optimization. In addition, one of the main concerns with most portfolio optimization is associated with the type of constraints considered in different models. In many cases, the resulted p...

Investment decision making is one of the key issues in financial management. Selecting the appropriate tools and techniques that can make optimal portfolio is one of the main objectives of the investment world. This study tries to optimize the decision making in stock selection or the optimization of the portfolio by means of the artificial colony of honey bee algorithm. To determine the effect...

Among all aspects of IT Portfolio Management (ITPM), we find the key concept of efficient frontier to be the most applicable illustration for managing IT resources as multiple heterogeneous IT portfolios. To better assist decision-makers (e.g., senior executives) in selecting the most qualified IT portfolio choice, we propose a new IT Portfolio Efficient Frontier model that incorporates decisio...

Investors use different approaches to select optimal portfolio. so, Optimal investment choices according to return can be interpreted in different models. The traditional approach to allocate portfolio selection called a mean - variance explains. Another approach is Markov chain. Markov chain is a random process without memory. This means that the conditional probability distribution of the nex...

Risk identification, impact assessment, and response planning constitute three building blocks of project risk management. Correspondingly, three types of interactions could be envisioned between risks, between impacts of several risks on a portfolio component, and between several responses. While the interdependency of risks is a well-recognized issue, the other two types of interactions remai...
