Abstract With the introduction of mean-variance model Markowitz took a giant step in modeling and optimizing portfolio type problems. But his model is based upon some assumptions that rarely they can hold in practice. For this reason, many researchers have taken steps both theoretical and practical to make some improvements to his standard mean-variance model. Up to now different risk criteria...

The growing number of company projects requires comprehensive management, project portfolio management (PPM), for strategic alignment and efficient use of resources. In parallel, companies face customers demanding higher value, and joint value creation with customers is considered a key success factor in the future. Project portfolios delivering products and services for customers implicate a l...

Portfolio selection is an important issue for researchers and practitioners. Compared with the conventional probabilistic mean-variance method, fuzzy number can better describe an uncertain environment with vagueness and ambiguity. In this paper, the portfolio selection model with transaction costs and lending is proposed by means of possibilistic mean and possibilistic variance under the assum...

In a qualitative research approach, an interpretive case study has been conducted. 26 experts from a large financial service provider of the cooperative banking sector were interviewed. The impact of organizational culture on the management of an organization’s IT project portfolio was subject to inquiry. We have identified three core dimensions of the organizational culture of the analyzed ban...

Portfolio construction is one of the most fatal issues modern finance, which can effectively gain returns or reduce risks. This study constructs portfolios in energy-related assets. Specifically, Monte Carlo simulations are carried out for a hundred thousand times order to discover efficient frontier and find minimum variance maximum sharp ratio portfolio. According simulations, American Electr...

U.S. regions are expected to follow the national trend towards investment in renewable energy as part of their electricity portfolio. The progress of energy portfolios that typically involves traditional methods, such as centralized nuclear and coal-fired generation, and towards cleanerand renewable-source generation will impact economic growth and public health. Renewable electricity productio...

Although data envelopment analysis (DEA) has been extensively used to assess the performance of mutual funds (MF), most of the approaches overestimate the risk associated to the endogenous benchmark portfolio. This is because in the conventional DEA technology the risk of the target portfolio is computed as a linear combination of the risk of the assessed MF. This neglects the important effects...

3 We integrate appealing features of Markowitz’s mean-variance portfolio theory (MVT) 4 and Shefrin and Statman’s behavioral portfolio theory (BPT) into a new mental accounting 5 (MA) framework. Features of the MA framework include an MA structure of portfolios, 6 a definition of risk as the probability of failing to reach the threshold level in each mental 7 account, and attitudes toward risk ...

This chapter introduces portfolio system design perspectives that incorporate concept mapping and the map-based user interface. It also presents a prototype of a portfolio system that has been developed based on the discussed perspectives, along with its capacities and the lessons learned in the design and pilot-testing processes. The author argues that a concept map-based design can enhance a ...
