Stock price and profitability of companies’ stocks are influenced by numerous internal factors as well as economic, psychological, political and other factors. As these factors may affect the price of companies’ stocks, identification of the impacts of macroeconomic variables and the factors contributing to stock returns can help investors to plan for the future. The aim of this article is to study the impacts of macroeconomic variables (oil price and exchange rate) and systematic risk (b) on ordinary stock return of listed companies in the Tehran Stock Exchange. This study has an applied method in terms of goal and descriptive method in terms of data collection and is classified as survey study. The data of the study has been collected during the years 2006-2010 by using Rahavard Novin Software Program, economic reports of the Central Bank of Islamic Republic of Iran and website of oil exporting countries (OPEC). The results achieved indicate that systematic risk (b) and oil price have a positive and direct relation with return of companies’ stocks in the meaningful level 5% and that there is no meaningful relation between exchange rate and return of companies’ stocks. In general, according to calculated R2, there is a meaningful weak relation between macroeconomic variables, systematic risk (b) and return of companies’ stocks. In other words, only 7.9% of changes of stock return relates to oil price and 24% relates to systematic risk. Other factors may also affect the returns of company's stocks.

occurrence of wastage Couse the reductions of the effectiveness of the system. these wastage can be associated with emergency failures. los of work time due to good planning and preparations of equipment and loss of work time without useful worand stops during the work.to reduce the effects of the mentioned Lesions the problems of effectiveness should be considered highto do this in this research. Because of the importance of automobile industry in the country and existence of high wastage in it the effort was on identifying the effective factors on reduction the wastage of producing in abhar Irankhodro factory. In this research by the use of dematel method, the effort was on identifying the indicators and classifying and determining the cause and relationships between them. Then with the help of fuzzy analytical hierarchy process method, The weight of each factors specified in a hierarchical was determined. Finally, The weight of six factors in total of 22 indicators in losses reduction of abhar Iran khodro factory were computed.

Today, The rapid development of industry, economy and technology in the world, and geographic boundaries become blurred (due to IT, ICT) and increasing competition in the production of goods and services and new technology is one of the critical and strategic goals of managers and organizations.

This study aims to investigate the relation between stock risk and short-term investment rate of the firms accepted in Tehran stock Exchange. Since stock is one of the limited and rare economical resources, investors attempt to optimize their return and they may pay no attention to the amount of risk involved, however it is critical to consider the risk factors involved in the investments. Present study covers the firms accepted in Tehran Stock Exchange in years 2004-2010. Since it is not possible to investigate all the firms, 181 firms were taken as samples for conducting this study. Stock risk was calculated based on Beta Coefficient Formula and after estimating the investment rate of these firms and calculating the regression and correlation coefficient, we examined the relation between these two variables. Based on the results from conceptual model, the effect of risk on the investment rate was positively significant. In other words, increased risk in stock leads to increased rate of investment changes. In addition, the effect of non-systematic risk is significantly higher than systematic risk.
