For the Market ratio category, you should
describe the overall trend of each company during the 4-year
period, for example, improved, worsened, relatively stable, etc. In
addition, you should present a summarized cross-sectional
comparison between the two companies. An example in the
profitability ratio category would be “Company A is overall more
profitable than Company...
