An investor has approached you about whether or not purchasing stock in the company would be a wise investment. Using your financial analysis of the company, you will send a letter to the investor summarizing your findings and explaining whether you recommend a stock purchase at this time. You will use information in the Form 10-K for the company you selected to complete this assignment. Using the correct formulas and a separate tab for each analysis, calculate the following ratios using Excel: Three liquidity ratios for the past 3 years, Three solvency ratios for the past 3 years, Three profitability ratios for the past 3 year. Please complete using excel with explanations. My excel is an old windows version.
