based on the work that i did. how would i compare the 2 companies (CAT AND DE) to their own annual histories as well as each other? over the 3 years of finacials i have calcualted.

also how would i tell what within their income/balance sheets, is driving the growth or deterioration if the coment ratios and ROE over time?

im really stuck on how to verberally explain these. also is the formula for ROE correct ?
