Instructions below: Stage One Final Individual Authentic Assessment Project The course project is designed to synthesize your financial studies into a comprehensive real-life case study. The main task is to identify an industry (or market sector) and then research the industry to identify the leading companies in the industry, analyze their finances, and provide your own analyst's opinion on the prospects for the industry and to identify which companies are best positioned to lead that industry. This is an individual or group project that will involve significant research and in-depth financial analysis. Stage 1 (4% of Grade, Due Week 2) Industry and Company Selection The company you select should be a publicly held company and be listed on a U.S. stock exchange (I WILL USE HOME DEPOT; STOCK SYMBOL HD).Your approach should include a discussion of the company's business model, core products or services, growth prospects and key cost items. If the company that is selected is engaged in foreign markets, you will need to discuss the potential for growth of those markets and any special risks those markets may pose, and risk management techniques for managing those risks effectively. The ultimate goal is to decide which company is best positioned to provide the most shareholder value in the future. This would require you to conduct the following analysis: Identify an industry to focus on (It is suggested that you use an industry that is expanding rather than consolidating, but the choice is yours to make). Explain why you chose this industry. Identify the top companies in the industry using your own selection of criteria (market capitalization, ROE, or any other criteria you wish to develop.) Your decisions on which set of criteria to use, are to be considered part of the project and your rationalization must be explained. Your research should include a survey of business periodicals, industry data from established sources, analyst reports, news articles, and journals as appropriate. Your paper should be supported by spreadsheets, graphs, and tables. The Stage 1 Industry and Company Selection is limited to 3-5 pages with a minimum of 3 to 4 references and no more than 3 attachments. (Use APA format which is Times Roman 12 pt. type font, double spaced, with cover page, content and reference page).
