Hello I need some help with Capital power's financial analysis for 2019-2020, I calculated the numbers for quick ratio, ROE and ROA, but I am struggling to find why the number fluctuated, and the reason for the change, also is Capital power in a financially sound position for 2019-2020.

Thanks! I would appreciate if you can focus on the change in ROE from 2019 to 2020, the number I calculated is 4.45 for 2020 and 3.84 for 2019, why did it increase, what's the reason behind it(industry, major project, policies, major eventsand etc).
