using apple financial statement or annual report I need to show trends that caused movement from on year to another . eg . current ratio in 2019is 1.54 and in 2018 was 1.12.. i need to show why there was an increase from 2018... i do not need to explain what is a quick ratio or how it is calculated. I need to describe the trend. I need to anaylze the trends in apple ratios. How can i do so?
