        The purpose of this study is to investigate the effect of tax avoidance on earning in formativeness as one of the explicit consequences of implementing sophisticated tax strategies. Hence,, we run multiple tests on a sample including 70 firms accepted in Tehran Exchange Market over the period 1387 to 1391. Evidence depicts that tax avoidance impairs earning in formativeness, for tax avoidance triggers not only an increase in opaqueness and complexity of financial reporting, but also a reduction in transparency of reports which eventually engenders difficulties for investors in understanding the reported earnings. Thus, investors will put little value on earning in their decision making process. Moreover, further research dealing with explicit consequences of tax avoidance contribute us to identify a reduction in the overall information environment of firms which are at a higher level of tax avoidance. This reveals that management will not be able to fully compensate the potential loss in earning in formativeness associated with tax avoidance (even by disclosing alternative information).

        Confidence in the capital market becomes dynamically valuable when interactive strategies with stakeholders are formulated for the long term to reduce the information asymmetry that has become an epidemic among companies. That is, a more responsive response to the level of expectations of this market under the supervision of relevant institutions. By reflecting on timely news content and honestly speaking, one can expect interactive functions and capabilities between companies with stakeholders in the form of theories such as Pygmalion theory that points to the re-formation of expectations in this market. It should be strengthened and the level of satisfaction with investing in this market will increase due to lower risk and higher return. The purpose of this research is Information Content of Financial Reporting and the development of interactive capability with stakeholders by Pygmalion Theory Test. In this study, in order to measure the content of financial reporting information, two criteria of timeliness and Reporting-Lag have been used. To evaluate the development of interactive capability with stakeholders, Delphi's analysis based on Likert-5 formulation has been used. Questionnaire for collecting research data for 142 companies in year 2019 was sent out of which 105 questionnaires were returned with the participation of managers of Tehran Stock Exchange. In order to fit and test the hypothesis, we used the partial least squares analysis. The results showed that Information Content of Financial Reporting had a positive and significant effect on development of interactive capability with stakeholders. Manuscript profile

        Using high frequency data from 33 member companies of the TEFIX30 (about 5 million data), this study examined the information content of limit order book in Tehran Stock Exchange. We try to find that does limit orders behind the best bid and offer provide useful information about stock value? And how much is their information share? We use two well-known methods based on a vector error correction model. Results show that based on Hasbrouck (Gonzalo-Granger) measure, contribution of steps 2 to 10 to price discovery is about 18% (25%) and also contribution of steps 4 to 10 that are not publicly visible is about 8% (10%).

        Financial statements should have general objectives rather than specific group interests. The possibility of forecasting earnings based on seasonal performance instead of the previous year's earnings and in terms of the contradiction between timeliness and the ability to verify earnings can be a new and thought-provoking issue. The present study examines stock price drift from the content of projected earnings forecast for quarterly operations. The research hypotheses were tested through univariate regression, multivariate regression and correlation coefficient tests using Eviews software. Findings of this study indicate that 1- Profit forecast based on quarterly performance has more verifiability than the previous year (profit stability). 2- The Verifiability of the year profit is more than the profit forecast based on the 9-month performance. 3- Stock price drift is expected on the day after the announcement of earnings and there are changes in earnings compared to the forecast of the previous season. 4- No relationship was observed between the volumes of shares traded the next day and the announcement of the forecasted profit and the changes in the profit compared to the forecast of the previous season.

        Because the knowledge of all aspects of financial performance for the economic decisions of users of financial needs, it is necessary to identify all revenues and expenses during the period be considered. For this purpose, the committee drafted new guidelines for accounting and audit report to the profit and loss reports for comprehensive profit binding in all units. In this paper, the information content of net income, comprehensive income and of the alternative candidates profit in the Tehran Stock Exchange. According to Standard No. 6, comprehensive income consists of net income(NI), Adjustment for foreign currency translation(FCT), Adjustment for unrealized gains/ losses on securities) and Annual adjustments(AA). Expected to report comprehensive income classified intelligence reports, financial times increase. If classified information is expected to increase its financial information. Due to the homogeneity of variables accounting, content relative to comprehensive income and Alternative candidate for income with Companies listed on stock exchange Tehran data over the years 2001-2010 Using multiple linear regression and the Wald test were studied. The results show that comprehensive income(Standard No. 6) for the explanatory power is stronger, and among income alternative candidates' net income plus FCT and AA has the highest content. This result with the research evidence Biddle and Choi(2006) in America, and Kiridaran Kanagaretnam(2009) in Canada is similar. Manuscript profile

        Purpose: The aim of this research is to investigate the capability of artificial neural networks and machine learning algorithms, including Support Vector Machine and Random Forest, in predicting the information content of accounting profits before its announcement in accepted companies on the Tehran Stock Exchange during the period from 2015 to 2020.Methodology: Daily data required for the research were collected using Rahnaward-e-Novin software, and a systematic random sampling method was used to select 88 companies. MATLAB was used for modeling artificial neural networks and machine learning algorithms, and Python code was employed to calculate abnormal returns in neural networks and machine learning algorithms. The information content of profits was measured through the test of the relationship between profits and abnormal returns, based on the model by Porti et al. (2018). The input variables for artificial neural networks and machine learning algorithms are technical indicators. Accuracy, precision, recall, and F-score metrics were used for performance evaluation.Findings: The results of predicting with three models of artificial neural networks, Support Vector Machine, and Random Forest showed that Support Vector Machine and Random Forest had higher accuracy than artificial neural networks in predicting buy, sell, and hold strategies, and only Support Vector Machine had the ability to predict the information content of profits among the three models.Originality / Value: Designing a predictive model for stock price movements in the next trading day using artificial neural networks, Support Vector Machine, and Random Forest as the main innovation of the research. The research findings can increase the speed of information dissemination to the market and attract it, which will reduce the impact of informational asymmetry and information-based trading and ultimately enhance market efficiency.
