This study discussed the Capital Assets Pricing model (CAPM) and its ability to measure the required return, the researcher tested this model on Amazon Company listed in S&P 500 during the period (2009-2016), to measure the impact of beta stock and market index return on the required return. Multiple regression model was used to test the effect of independent variables (Beta stock, Market Index Return) on the dependent variable (Required return), it should be noted that there is a statistically significant impact of the US stock market Return (S&P500) and Amazon stock Beta factor on Amazon stock required return, and the study model explanatory was 20% , this means that 20% of the changes in the required return are due to beta and market return, and 80% of the changes due to other factors, also find that CAPM can be applied on efficiency markets and huge companies. The researcher recommends applying the variables of the study on a group of large companies in the S&P 500 index, and looking for other factors that may affect the required return.

This study aims to examine the relationship between the investment in current assets and profitability and liquidity for industrial companies listed in Amman Stock Exchange, the researchers measured the investment in current assets through the ratio of current assets divided by total assets (C.A\T.A), profitability measured by return on assets ratio (ROA), and liquidity measured through the Current Ratio (C.R). The researchers found that there is a relationship between investment in current assets & profitability, liquidity in companies listed in Amman stock exchange- industrial sector, and the researchers found that the ratio of (44.1%) of the changes that occur in the Return on Assets (ROA) and Current Ratio (C.R) belonging to the change in investment in current assets. Therefore; researchers recommended industrial companies to follow a moderate policy of investment in current assets. So that the ratio of current assets to fixed assets shall be moderate, reflecting a reasonable degree of risk and acceptable profitability which balanced between risk and return.

This study aimed to discuss concerning the link between savings and investment, and highlight on most of the past studies concerning this relationship are cross-sectional in nature. The obvious difficulty with such studies is the homogeneity assumption that is usually made across the countries under investigation. In light of this, the study tried to fill this gap in some ways by attempting to investigate the causal relationship between savings and investment in Jordan using relevant econometric techniques, like Augmented Dickey-Fuller (ADF) test in a regression & Johansen co integration test. The evidence arising from the study suggests that, savings and investment are co-integrated. In other words, there is no reason to suspect either a long-run or equilibrium relationship between these two variables. This could also be interpreted to imply the existence of high capital mobility. Furthermore, a unidirectional causal relationship between savings and investment in Jordan running from savings to investment was observed, and the main findings in this study were: Johansen co-integration test result shows evidence of co-integration implying that there is a long run relationship between GDP and savings, investment and FDI in Jordan. Savings and domestic investment have long run positive and significant impact on the Jordanian economy while FDI has negative but insignificant impact on the economy

This study, using longitudinal data analysis, attempts to address the question of whether CSR is linked to financial performance for PLCs in Malaysia. Despite CSR disclosure being at a nascent stage in Malaysia, the findings of this study solidly support the outcome of the majority of results in developed markets. It was found to be positively related to financial performance. This suggests that local firms can achieve advanced levels of financial performance if they engage in social activities. The findings also confirm that there is limited evidence of a significant effect of CSR on financial performance in a long-term relationship.
