Investigating the Impact of Accruals Accumulation on Investor's Non-Homogeneous Belief

Investigating the effect of changes in accruals on the investor's heterogeneous belief and increasing the knowledge of investors and managers to decide on the purchase and sale of shares. Regression analysis was used to test the research hypotheses using combined data. The results of this study show that the variability of accrual items has a positive effect on the investor's heterogeneous belief and the effect of the variability of accruals on the investor's heterogeneous components in high growth companies compared to low growth companies and in small firms compared to Big companies are bigger. The fluctuation in accruals changes increases the uncertainty in investors' beliefs, and the false response to the information received indicates that they increase or decrease the stock price. The factor of growth and size of companies is known as one of the most important variables in the user's decision making. Contribution: It is expected that the results of research can be useful for future researchers and ultimately affect the quality of research, knowledge and decision making of managers and investors.
