in the research we try to introduce “network matrix” in selecting optimizing portfolio for active management in investment companies, to evaluating obtained portfolio of this, with this aim that have high efficiency in relation to market portfolio efficiency. first matrix (portfolio) is value-growth stocks that are classified by standards p/e and p/b and second matrix (portfolio) are an aggress...
uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
Background: Portfolio is one of the most important tools to inclusive education as well as its evaluation. It is a useful tool in the promotion and development of skills such as critical thinking, and can reduce the gap between theory and practice. Object: The aim of this study was to revision on portfolio of community health nursing. Materials and Methods: This is a qualitative study con...
In this paper, we propose formulations and algorithms for robust portfolio optimization under both aleatory uncertainty (i.e., natural variability) and epistemic uncertainty (i.e., imprecise probabilistic information) arising from interval data. Epistemic uncertainty is represented using two approaches: (1) moment bounding approach and (2) likelihood-based approach. This paper first proposes a ...
the credit portfolio management and the optimal credit portfolio selection are identified as one of the most effective factors in banks’ credit risk. two main strategies in this regard include diversification versus concentration. in this study, at first, the status of diversification of iran’s banking sector is analyzed, then the relationship between diversification of the credit portfolio and...

Abstract These days the use of portfolio assessment is very popular. If it is believed that students at all levels should be doing more than studying for tests; teachers should be doing more than teaching to tests; students should take a more active role in the learning process; and, then the portfolio assessment is an idea worth exploring.. The aim of this study was to introduce portfolio asse...
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...
