Research purpose: This paper is to investigate the effect of the policy of institutional investors, price synchronization and profitability index on the risk of falling stock prices between 2011-2015 (1390-1394).
Research method: The research is conducted through desk resarch and statistical analysis. To test the hypotheses, the regression and correlation coefficient as well as the t-test are used to determine the stationarity of variables Fisher’s ADF test were used Further more, to estimate the model panel method and the F lemmer test as well as Hausman test were used. Also, Excel and Eviews 8 software were used to analyze the data and to test the assumptions of the research.
Conclusion: The results indicate that there is a negative and significant relationship between the policy of institutional investors with the risk of falling stock prices, which means that the existence of institutional investors has the incentive and management ability to hide or delay the publication of bad news. This eventually reduces the likelihood of falling stock prices. There is also a positive and significant relationship between stock price synchronization and the risk of falling stock prices. Increasing synchronization will increase the risk of falling stock prices. There is also a negative and significant relationship between profitability and the risk of stock price collapse, so that increasing company profitability significantly reduces the risk of stock price collapse
