first this exam is brutal! second, up move is 1.15 the solution says the down move is .87, where does it come from? i thought they have to give you the UP and DOWN move of the stock. help!
D = 1 / U
d=1/u= 1/1.15 = 0.87
omg…i think i am in panic mode. 1/U duh! thanks all!
haha the exam after this, wait till you get towards the end… completely brutal
