On account Scrutiny in asset growth understanding, an anatomic approach is used to break down total asset growth to its three components and its effect on cross-section stock return is investigated using dual portfolio analysis and Fama-MacBeth (1973) two step regression from 1379 to 1389. The results confirm asset growth positive effect and reject the effect of net operating asset growth because the latter effect depending on weighting scheme and time horizon of subsequent stock return can be positive, negative or even statistically insignificant. The research Evidences indicate asset growth is self-inclusive and its explanatory power of is not appertained by anyone of its subcomponents. So, it cannot seek the reasons of the asset growth anomaly appearance in net operating asset anomaly. It seems that the source of asset growth financing (Criterion of asset growth decomposition) does not matter in asset growth anomaly occurrence.The main purpose of this paper is analysis of total asset growth anomaly in Tehran Stock Exchange that emphasizes on the test of relation between total asset growth and net operating asset.

This condition is, however, not sufficient. Firms require financial management capability to realize the rents present in their strategic assets. The firm-specific nature of strategic assets implies that they be financed primarily through equity other less specific assets should be financed through debt. In this study , we test these hypotheses using data from companies listed on the Tehran Stock Exchange, during 2000-2010. We run panel regression with STATA12 software. We find the negative correlation between the asset specificity and financing through debt and a positive correlation between assets specificity and the firms are financed through equity.Possession of strategic assets is a necessary condition for sustained competitive advantage.

Most of investors trace market movements by using indices. Therefore, market indices should show transparent picture of capital market trend, in a way that facilitates past and present trends and decision making for future. By using the event study methodology and analyzing data of 165 firm-year within period of first quarter of year 1382 to first quarter of year 1391,results indicate that market do not show significant price reaction to changes in top 50 index list. But results of analyzing abnormal stock trading volume and bid-ask spread difference show stockholders liquidity reaction to inclusions and exclusions. Robustness checks has performed for comparison between systematic risk and idiosyncratic risk, before and after announcement day. Results show that systematic risk has not changed in both sections of inclusions and exclusions before and after announcement. In other words, announcement of inclusions and exclusions do not have effect on systematic risk. About idiosyncratic risk, there is no significant difference between before and after announcement in inclusion situation, but in exclusion situation, idiosyncratic risk before announcement is more than systematic risk after announcement. Also exclusion news has decreased idiosyncratic risk.The purpose of this research is to investigate the impacts of changes (inclusions and exclusions) of top 50 index list on price and trading volume in Tehran Stock Exchange.
