The instructions say to find the count and proportions of companies with market cap over the median and mean for each year. However, by definition, exactly half of the companies are going to have market cap over the median each year. Can you please clarify this instruction?


Well, for the median the proportion will be as you say, but the rest of the statistics will be different. You could handle the median proportion in the text. Plotting the counts WILL show variability.
