Abstract
The main purpose of the shareholders in the company is to increase the stock returns. In this regard, quantitative and qualitative information about the company can help investors in increasing stock returns, so the purpose of this research is to investigate the role of financial reporting tone in explaining the stock returns of state-owned companies with an emphasis on text mining.
In order to empirically investigate this issue, textual analysis methodology and information of 29 state-owned companies admitted to the Tehran Stock Exchange between 1392 and 1398 have been used. Identifying the tone in the reports of the board of directors was done using the text mining method in the R programming environment. In order to test the hypothesis of the research, the average comparison test of two societies was done using Stata software.
The results of the research show that the tone of financial reporting is effective in explaining the difference in the return of shares of state-owned companies, and statistically there is a significant difference between the return of shares of state-owned companies with a positive and negative tone of financial reporting. It is recommended that standard setters pay more attention to the audit of written information of financial reports, because if managers' opportunistic use of tone is not audited; Users' confidence in the written messages of financial reports may decrease. The results and findings of this research can be effective for the development of text mining tools in the field of accounting and finance.
