I was thinking on making a thread on the formulas your basically 100% sure that will have to be used in the level 1 exam, Ill start with:
-ROE (DuPoint and the other way) and Cash Conversion Cycle
MMY, BDY, EAY, HPY. div discount model, WACC, CAPM, ( with crp as well), sharp ratio, jensens alpha, m^2, treynor ratio just to name a few.
The way to calculate 1 year fowar 2 years from now is my biggest struggle i cannot get my head around it as much as i try i know i will see that in the exam.
