What do the numbers tell the analyst about management decision and performance impact? 

For instance what does the decreasing profit margin numbers over time mean? 

Why is the equity multiplier so much higher for 2018 than other years? 

I thought a lower turnover asset rate would be problematic but in 2018, the ROE is still very high. 

 

2019: ROE = -65.45%; Profit Margin = 15.38%; Turnover Asset Rate = 1.38; Equity Multiplier = -3.08

2018: ROE = 330.27%; Profit Margin = 15.71%; Turnover Asset Rate = 1.02; Equity Multiplier = 20.54

2017: ROE = 75.77%; Profit Margin = 18.47%; Turnover Asset Rate = 1.56; Equity Multiplier = 2.63
