In this research, we proposed a new metaheuristic technique for stock portfolio multi-objective optimization employing the combination of Strength Pareto Evolutionary Algorithm (SPEA), Adaptive Neuro-Fuzzy Inference System (ANFIS) and Arbitrage Pricing Theory (APT). To generate the more precise model, ANFIS has implemented to envisage long-term movement values of the Tehran Stock Exchange (TSE)...

In this paper, real options theory is utilized to evaluate the effect of uncertain electricity and CO2 costs on speculation conduct. Methodologically, the allegiance of the newspaper in this appreciation is that uncertainty is not just stopped down as far as stochastic processes and their fluctuation, additionally as far as expected and acknowledged procedures, i.e. the procedures, w...

Quantifying the variability in the delivery of ecosystem services across the landscape can be used to set appropriate management targets, evaluate resilience and target conservation efforts. Ecosystem functions and services may exhibit portfolio-type dynamics, whereby diversity within lower levels promotes stability at more aggregated levels. Portfolio theory provides a framework to characteriz...

Students can collaborate with other students and their lecturers through e-Portfolio. This paper explains the importance of uses and gratification theory in an electronic portfolio.

Modern portfolio theory is based on a rational investor choosing the proportions of assets in a portfolio so as to minimize risk and maximize the expected return. In this paper, we investigate the applicability of different stochastic search heuristics to the problem of finding the optimum portfolio. We compare their performance on two problems with known solutions. 1. Portfolio Optimization Gi...

The old adage about putting all of one’s eggs in one basket was thought wise long before the advent of modern portfolio theory and the important results of Markowitz (1959) and others. However, despite the anecdotal imperative to investors to diversify their portfolios, the empirical reality is that diversification rarely takes place as recommended by portfolio theory. In this paper, I demonstr...

We begin this paper by first comparing the theory of present-day portfolio selection, which is a theory for standard investors (whose utility functions take on only the single argument of portfolio return), with a developing theory for non-standard investors (whose utility functions are allowed to take on additional arguments). Examples of additional arguments are dividends, liquidity, social r...

This article investigates the issue of international portfolio diversification with respect to the three largest financial markets in the world—namely the US, Japan and the UK. In addition to making use of traditional portfolio analysis, we also suggest a procedure to calculate bootstrap correlation coefficients that can take into account the dynamic structure between the markets as measured by...
