Use profit reports from the annual Fortune 500 list to discuss whether these large firms appear to be making normal or economic profits or losses. Explain your answer clearly and concisely. How wide are the inter-industry differences? Use the range of earnings from the ten highest to the ten lowest and the “all 500” composite return to stockholders’ equity to answer this question. Compare this to the current opportunity cost on invested capital (measured by interest rates paid on federally insured bonds or certificates of deposit) that would represent a “normal” return.
