due to project evaluation complexity and resource constraints, the project portfolio optimization is numerous decision making challenges. hence, many researches have been done to introduce model and methods for portfolio optimization. but most of them have not considered the interaction between projects. considering the interactions between projects increase complexity of portfolio optimization...

Alternative assessments have evolved from an epistemological change in education. They see assessment and instruction as two sides on the same coin which go hand in hand. The traditional roles of both teachers and learners are, consequently, modified which is essential for better language development. In this line, the present study aimed at comparing the effects of portfolio and journal writin...

financial derivatives are new instruments through which hedging, investment and arbitrage are done in a modern economy. although the word 'derivative'primarily reminds us of options and futures, the major focus of the equity derivatives industry worldwide is on index derivatives. launching index options and index futures in tehran stock exchange, not only increases financial market de...

Executive summary. The current low-yield environment has led many bond investors to ask whether they should prepare for an eventual rebound in yields by purchasing individual bonds. The potential benefits of this strategy are often exaggerated. More important is that, for most bond investors, bond mutual funds and their exchange-traded fund (ETF) counterparts provide a number of advantages over...

index tracking is the process of developing a portfolio that reproduces the performance of an index. the tracker portfolio has relatively good diversity and low turnover and low transaction costs. in this paper we applied a binary programming model for index tracking problem. in this model the number of assets for portfolio construction is defined by portfolio manager. the robust optimization f...

All hedge funds are not created equal. A poorly chosen portfolio of hedge funds can produce disappointing results. All fund of funds managers are not created equal, either. A poor choice of fund of funds managers can yield disappointing results. This article is designed to outline the value proposition of a fund of hedge funds operation. We conclude that fund of funds add value primarily throug...

Recent developments in the theory of choice under uncertainty and risk yield a pessimistic decision theory that replaces the classical expected utility criterion with a Choquet expectation that accentuates the likelihood of the least favorable outcomes. A parallel theory has recently emerged in the literature on risk assessment. It is shown that a general form of pessimistic portfolio optimizat...

The bond portfolio management problem is formulated as a stochastic program based on interest rate scenarios. The coefficients of the resulting program are subject to errors of various kind. In this paper, we complement the theoretical stability results of [10] by simulation experiments. Adapting the approach of [16] to problems based on perturbed yield curves, we then provide bounds for the op...

criteria in household portfolio. to do this, the data which are related to the asset price are used including: bank deposit, bonds, stock, exchange, coin, land and housing in time period of 1997 to 2011. in this research, portfolio var id calculated in the confidence level of 90%, 95%, and 99% and in time periods of one year and 14 years. after calculating returns, return standard deviation, co...
