This study aims to estimate and predict the effect of stock prices on profit volatility, net profit, and comprehensive income on the Indonesia Stock Exchange for the period 2014-2019. The study uses quantitative analysis with secondary data consisting of 98 banking companies on the Indonesia stock exchange from 2014 to 2019. The results prove that the share price has a significant effect on net income and comprehensive income but does not have a significant effect on profit volatility, so that net and comprehensive income has relevance to the share price and investors can make both variables in conducting further fundamental research. Previous studies measured the level of volatility of earnings, net income, and comprehensive income on the share price, but when trialing other approaches by causality, share prices affect net income and comprehensive income but not for profit volatility. In this study, however, the change includes detailed income variables due to Financial Accounting Standard No. 1, a shift in terms from profit and loss statements to systematic profit and loss statements.

This study aims to investigate the effect of risk management on earnings volatility on shares of banks listed in Tehran Stock Exchange. The statistical population includes all 20 listed banks in Tehran Stock Exchange over the period 2009-2015. As the number of listed banks in Tehran Stock Exchange was limited, census method and multiple regressions in panel data were used to collect the data and to test the hypotheses, respectively. In this study, earnings volatility was calculated given in Dichev and Tang (2009) [Dichev, I. D., & Tang, V. W. (2009). Earnings volatility and earnings predictability. Journal of Accounting and Economics, 47(1), 160-181.]. The results indicate that the coefficient of risk management was -0.20 with Sig. = 0.002; therefore risk management maintains a negative effect on banks’ profitability volatility. In addition, stock return coefficient is 0.0053 (Sig. = 0.000) which indicates a positive effect on earnings volatility. The coefficients of dividend ratio, firm size and liquidity ratio were 0.023, 0.071 and 0.059, respectively and they have significant and positive effect on earnings volatility.
