Abstract

In this research has been tried to review the effect of various methods of financing on share yield of accepted firms in the stock exchange of Tehran during 2005-2009. For this reason, the firms which financed through loan or increased capital have been selected and based on noted data on financial statements of them. the effect of two given financing methods (loan & increased capital) on return of their equities following recognition normality of studied variables by Kolmogorov-Smirnov test, correlation analysis and regression analysis. The state of accepted firms in stock exchange of Tehran compared to effect of various financing methods on return rate of equalities during given years has been reviewed. The results of research show that it isn’t possible to claim that the financing through increased capital has positive influence on share yield of accepted firms in the stock exchange of Tehran. On the other hand, could be claimed that, financing through loan has positive influence on share yield of accepted firm in the Tehran stock exchange.
Keywords: Financing, Share yield, Tehran stock exchange


1. Introduction
The increasing development and complexity of economic activities as well as fast evolution of commercial transactions in the modern world whether inside or international trade and demand of commercial and production companies to maintain capacity by developing of activities and investment designs to hold or increase competitive power in the inside and world areas have been increased demand of these firms for financial resources. The capability of firm in determination of potential financial resources in order to investments and providing suitable programs include of main factors of development in firm. In these situation, there is necessary www.ccsenet.org/ijbm International Journal of Business and Management Vol. 7, No. 3; February 2012
Published by Canadian Center of Science and Education 95 to benefit from techniques of financial managers in management of firms. Providing right financial policy strengthens firm’s capability in reaching strategic amiss.

2. Conceptual Framework
2.1 Main resources and structure of financing
The supply financial resources is the most important issue in financial management. The awareness of financial managers on various methods of financing (provision) causes to be possible continuity of firms and the financial structure of firm be flexible law and process current facilized. In some of cases financial resources supply is along with charge payment and commitment. The evaluation of various financing is interacted with evolution of related financial charges to them. Thus, it is necessary that, both categories to be taken account systematically (Niku Maram & Colleges, 2009, 129). Figure (1) shows decision making tree related to various financing methods:

2.2 Pyramidal order of financing hypothesis
The conducted research by Donaldson in 1961, are confirmation of more reception of interior funds in the firms. If, interior resource isn’t adequate to investment by firm, then, firms trend toward commercial exterior financing which in first step, the borrowing, then convertible secure sties (Issuance of securities) and finally issuance of stock will be considered. Mayer’s introduced such hierarchy as pyramidal order of financing which has been showed in Fig 1.


3. Research Background
Donaldson, Mayer’s & Bradley in 1961, observed in research on ” operation of financing in great firms ” that, the management supports interior financial resource, as new funds resource severely and even put aside exterior ones and if more demand to exterior financing resources, use borrowing. Even when, price to profit rate is high and with suitability of common stock sale time, They relict to issuance of stocks so that supplied investments charges include of investment in inventory and other current wealth’s , from interior resources. Kurwar, in 1983, Skit & Molnz in 1986, Don & Michelson , wormalin & Dianjil, Damjal & Rais, Conclude in own research that moderately while firms issue stock, decrease stock cost and in contrast while proceed to redeem it, the costs increase.
Miyers & Majulf reviewed effect of new stock issue on real and inherent value of equity by asymmetrical data and found that, what price of equity be high, lower value obtained by new shareholders. Smith in 1977, reviewed the impact of new stock issue on price and return of stock and found that given event has negative impact on stock price. In recent studies, the significant unnormal negative return is created as to finanicing announcement.
Research show that avaraging 3 percent of stock price of industrial firms which issue seasonal common stock, has been decresed. Most theoric explantions, indicate that, this decline is result of negative data that has been taken through new stock issue announcement to market. Antoniou & others reviewed in research under deterministic factors of firms capital structre in 2002, the impact of pyrimidal rates on capital structure and found that firms set influential factors on capital structure so that to obtain optimum one . Other research has been conducted by Mateus & Balla on selection of optimum capital structure in 2002, they use regerssion method hybrid data for 55 firms since 1995 until 1999 and conclude that, return of firm has direct
relation whith pyramid. Richardson & Sloan in own research under “relation of exterior financing with future share yield in 2003, reviewed all exterior financing with expected share yield. They found that, future return forecast of stocks depends to capital structure mostly.

7. Discussion and Conclusions
With regard to analysis of hypothesis, the conclusions are as fallows: As observed in table (10), the results of research show that, firms which proceed to increase capital in thehran stock exchange in order to financing, didn’t have positive effect on their share yield. this result is consistent (result of first hypothesis) with Smiths results (1977), Kurwor (1983), Skit and Molnz (1986). Dan & Michelson (2000), Miyeis & Majulf (2001), Richardson & Slaon (2003), Novravsh (2005).
But firms which proceed to Loan in thehran stock exchange in order to financing, have positive effect on their share yield. this result is consistent (result of second hypothesis) with Margaret results (1998), Bentstwart & Glasman (2001), Mateos & Balla (2002), Izadinia (2009).
8. Recommendations

This research, with regard to resultant evidence of study and results of hypothesises test, provided the recommendation to legislator agencies and thehran exchange, firms management, share holdere, banks, creditor, credit institutions, students, authors and eduational centers as follows:
1) While, financing thourgh increasing (stock dividend and issuance of stock) will cause to decline of any share temporarily and this decline would have negative impacts on cost share yield of that year, the gross change of capital belonged common. stock, is higher in comparison with other financial supply tools. it means that,
www.ccsenet.org/ijbm International Journal of Business and Management Vol. 7, No. 3; February 2012 Published by Canadian Center of Science and Education 99 common stock is expensive resource of financial supply and causes to increased capital charges of firm, thus it is better that the firms use this resources which have more profitable inverstment opportunities.
2) On the other that, while the long-term loan is constant nearly, if the resultant of these loans be higher than interest cost, the borrower firm will be benefit from these loans with regard to explonation, and based on research finding by considering positive impacts of financial supply though loan (long-term, short-term loan) on share yield of firms and negative effect of financial supply through increased capital (stock dividend and issuance of stock) to shareholders, creditor and investors, it is recommended that , in desions basesd on using financing methods, be caution that be successful in investments of firm.
