The occurrence of bankruptcy in the world's monetary systems is highly sensitive, as the systemic risk consequences associated with this phenomenon can have very devastating effects on the monetary and financial system of countries and lead to severe political and security crises. Valuable laws and regulations have been developed to assess the status and performance of the bank and to warn of the crisis leading to bankruptcy in the world. The situation of some countries, including Iran, is different economically and in other respects. In this study, through interviews with banking experts and thematic analysis, the researchers identified 17 indicators with a high degree of impact on bankruptcy, that five of them are specific to the current conditions of the Iran’s banks. these indicators could be usefully in every suitable ranking model. the proposed quantitative model could be used in case study researches for future research to know the important problems of high high risk banks.

In this research, the relationship between earnings to stock per price ratio (E / P ratio) with sales future growth and stocks systematic risk in listed companies in Tehran Stock Exchange is investigated. The purpose of the research is to determine whether investors are paying attention to the quality of information presented (earnings per share), and reflects this on corporate future sales growth and the systematic risk of stocks. It also examines whether there is a meaningful relationship between E / P ratio and future sales growth. The sample of this research includes 146 listed companies in Tehran Stock Exchange during the period of 2011-2016. The linear regression model was used to test the hypotheses. The research findings show that there is a negative relationship between earnings per share (E / P) and future sales growth. In fact, companies that have a higher profit / share / E / P ratio have lower sales growth. Also, the results of the research show that there is a reverse relationship between profit to share price (E / P) and systematic risk (β). In fact, in companies with an E / P ratio, the systematic risk (β) was lower. Other research findings show that there is a positive relationship between earnings per share (EPS) and future sales growth. The results also indicate an inverse relationship between earnings per share (EPS) and systematic risk (β).

The modern internal auditing has recently been considered in Iran. Therefore, many of its aspects, including internal audit quality(IAQ) and Internal audit quality improvement strategies(IAQIS), have not been clarified yet. Also, limited areas of IAQ have been considered in previous research. In order to explain and describe the various aspects of IAQ and IAQIS, we have interviewed internal audit stakeholders. So, by using the qualitative approach and grounded theory, internal audit stakeholders (user, executive, regulators and standard setter) were studied for the first time in Iran. In this regard, 33 people were interviewed from late 2016 to early 2017. In addition, in this regard, 30 papers and seminars which published in Iranian professional magazines that reflect the viewpoints of the above-mentioned stakeholders were also used. The data were analyzed by using the open coding, axial coding & selective coding approach that is specific to the grounded theory and major categories, categories, and subcategories (concepts) were extracted. Using a system model approach that includes inputs, process, outputs, outcomes and contextual factors, the IAQIS model was designed. The model incorporates multidimensional of IAQIS. Strategies include inputs, performance, outputs, and contextual factors which are affecting IAQ. Due to the gradual expansion of the modern internal auditing in Iran in recent years, to achieve and improve IAQ, these multidimensional strategies can apply in engagement level, internal audit function level, firm level and national level.

To measure stock overvaluation, Rhodes-Kropf et al (2005) research and to measure abnormal stock returns and their volatility over time, the Fama and French (1995) three-factor model has been used. The population of this study, included of 64 companies in listed companies of Tehran Stock Exchange was selected systematically, and ten-year period from 2005 to 2014 was used for the statistical & necessary tested on them. The results using multivariate linear regression using panel data and fixed effects approach suggest that stock overvaluation has a positive and significant impact on abnormal stock returns and volatility of in over time. In other words, by increasing the stock over valuation over time, abnormal stock returns and their volatility significantly increased. It is recommended to business executives by providing the necessary background for a realistic evaluation of the stock, the necessary fields in order to reduce the abnormal returns of stocks and their volatility to bring over time.

One of the assumptions of efficient market is that investors react to new information. The evidence show that investors overreact to new information. They tend to be either over-optimistic or over-pessimistic. Therefore equity prices are not equitably determined by the "true" forces of market supply/demand and are not in equilibrium most of the time. Although stock prices would go abnormally high (low) due to investors' Overreaction in the initial period, they have a tendency to adjust themselves back to the equilibrium level in the subsequent period.
This research investigates the Investors' overreaction in the Tehran Stock Exchange. The results indicate that stocks in the best (worst) performing experience, a reversal of fortune in the following years.
