Abstract EN

This study aimed to identify the impact of investing in securities on the profitability of Islamic banks in Saudi Arabia, using the indicators of the Sharp model.

The study included the data of the 4 Islamic banks in Saudi Arabia.

The study covered the period from (2011 – 2020).

The impact of the indicators of the Sharp model on the profitability of Saudi Islamic banks was studied using the analytical descriptive approach.

The indicators of the Sharp model included the risk return (RF), the return of the portfolio investment in securities (RP), and the risk of the portfolio of investment in securities (δ p), while the financial indicators of profitability included the following: Rate of Return on Equity (ROE), and Return on Investment Rate (ROI).

The study reached a number of results, the most important of which are: There is no statistically significant effect of investing in securities on return on investment (ROI), and return on equity (ROE) in Saudi Islamic banks.

There is also a statistically significant effect of both portfolio risk in securities (δp) and risk-free return (RF) on both return on investment (ROI) and return on equity (ROE), in Saudi Islamic banks.

In addition, there is no statistically significant effect of portfolio return on investment in securities (RP), on return on investment (ROI), and return on equity (ROE), in Saudi Islamic banks.

The study recommended that more studies should be conducted to find out the effect of investing in securities in Saudi Islamic banks, using other models such as (Trainor - Jensen).
