The study aims to compare the effects of employing investment deposits (joint and specified investment deposits) in Islamic banks, and investment deposits (term deposits and deposits with notification) at conventional banks, on shareholders’ profitability, represented by the earnings per share (EPS), in light of operational profits as a controlling variable. Data related to the study variables was collected from the annual financial reports published by the study sample banks, during the period (2009-2018). The study relies on multiple regression to test the hypotheses of the study. The high adjusted R² to explain the change in EPS for Islamic banks model as compared to conventional banks, is a result of the high difference between investment deposits (specified and joint) at Jordanian Islamic banks and investment deposits (term deposits and deposits with notification) at Jordanian conventional banks. The study found that it is important for the managements of Islamic banks to adopt a uniform method to combine speculative funds, in order to develop and improve shareholders’ profitability. The study recommended Islamic banks to follow practical, methodological and transparent approaches to calculate the rates of Murabaha profit margins between shareholders and depositors, while also taking into consideration some of the issues which could be harmful for the competition between Islamic and conventional banks.

The research was conducted with the aim of knowing the effect of the CAMELS ratio either partially or simultaneously on stock prices. The CAMELS ratio (Capital, Asset Quality, Management, Earning, Liquidity) is used to measure the soundness of a bank, where by the better the soundness of the bank, the more profitable the bank will be for potential investors and other interested parties. The population of this research consists of the four state banks documented on the Indonesia Stock Exchange over the 2012-2019 period. The sample selection technique is a saturated sampling. This study provides the results that partially CAR has a significant effect on the share price of government banks listed on the IDX. Meanwhile, NPL, NPM, ROA, and LDR do not have a significant effect on stock prices of state banks listed on the IDX. The results of the regression analysis show that, together the CAMELS ratio, which is proxied by CAR, NPLS, NPM, ROA, and LDR has a positive and significant influence on the share price of state-owned banks documented on the Indonesia Stock Exchange, so this can be used as a reference for investors in predicting the share price of a state-owned bank before investing in shares.
