The research aims to highlight the role played by the tools and models of valuation of ordinary  shares in making financing and investment decisions through ordinary shares, by taking the  shares of the banks covered by the research during the period (2010-2020) and by five banks  working in the fields of banking, and it has been possible to analyze the research variables and  extract their real values and stand on the returns and risks of ordinary shares and determine  the extent of their role in reducing financial failure,  It has been reached to accept the main  hypothesis of the research, and this is consistent with previous reference studies on raising the  value of the share leads to an increase in the return and risk of the stock in general and then  reduce financial failure, and differ from the results of other studies that disagree with this opinion. In the light of this, a set of appropriate recommendations could be developed.
