A task to analyze these three publicly listed companies in Saudi Arabia (1. Almarai Co. 2. National Agricultural Development Co. 3. Saudia Dairy and Foodstuff Co.). You will have to perform an analysis of these companies, providing an interpretation of their performance against the industry and 5 years of previous performance. You must look at matters of Liquidity, Asset efficiency, Profitability, Solvency and Market Value. I also want you to perform a DuPont analysis breaking down the Return on Equity.
