Application of asset pricing models: evidence from Saudi exchange

This study examines the relationship of auditor tenure and audit quality in four European countries, namely Germany, France, Italy and Spain, with the innovative GMM (Generalized Methods of Moments) model during the period from 2005 to 2013.
Two GMM methods are used with two alternative definitions of crisis – the main and the robustness method. The results agree regardless of the fact that some of the control variables are excluded in the robustness test.
The results support the finding that in Spain, there is an impact of auditors’ long-term tenure on discretionary accruals, affecting auditors’ quality and independence indirectly. In addition, the crisis affected Germany and France as far as the change in negative and positive values of GDP is concerned. In this respect, the crisis affected the above two countries when the years before and after the crisis are considered as a robustness check. The results contain important implications for accountant regulators and policy makers.

The published financial statements are considered one of the most important sources of information that investors rely on in forecasting stock performance or even judging the organization’s ability to cover short-run liabilities. Cash flows play a core role in maintaining a high market value for its shares. Hence, this study came to analyze the explanatory value of the cash flow statement in explaining stock volatility (SV) in the Qatar financial market. Study data were collected using published financial statements from a sample of 44 Qatari-listed companies throughout 2013–2019. A panel cross-sectional data technique using the E-views program was used to analyze the data. The study results show there is a positive and significant impact of cash flows from operating CFO activities on SV, indicating that the higher change in CFO increases stock volatility. This means that operating cash flows give significant information to investors, and it is reflected in the stock price movements directly. Also, the cash flow from CFF financing activities has a positive and significant effect on SV. This means that CFF affects stock prices, causing greater changes and fluctuation in stock returns. This is because one of the major components of CFF is dividends, which affect directly stock prices and stock returns. In contrast, there is an insignificant effect of CFI on SV, which may indicate that investors do not build their investment decisions based on CFI. Accordingly, the cash flow from investing activities failed to explain the stock volatility of the listed Qatari companies.

East African firms are experiencing economic growth and are attracting foreign investment in the form of equity capital and loans. However, there are concerns about whether the structure of the capital and managerial ownership of these firms can influence their growth. The study examined the relationship between capital structure and firm value in East African countries and how managerial ownership influences this relationship. Sixty-five (65) listed firms in East Africa were selected for the study. The study employed a GMM estimation technique. The evidence showed that leverage has a significantly negative impact on the value of firms in East Africa, suggesting that higher debt would result in a decrease of firm value. The implication of this result is that firms can increase their value by reducing their leverage level. Moreover, the study found that managerial ownership had an inverse and significant impact on the relationship between leverage and firm value. The conclusion is that leverage decreases the value of firms in East Africa. Another conclusion is that owner-managers can use debt capital more effectively to increase firm value than non-owner managers. The implication of this result is that firms managed by owners can borrow more for their operations because it would increase the value of the firms. This study is the first to examine how managerial ownership moderates the relationship between capital structure and the value of firms in East Africa, which has a unique political, social, cultural and economic environment.
