@David Harper CFA FRM Let me start by saying Happy 4th (belated) :) and thanks for taking the time for the clarification. Yes when I plugged the 10.63% , the variation of the std-dev formula yielded the expected value of 2.984%. I do prefer to use the formula Σ[u(i)^2]/(n-1) -...

In reference to P1.T4.VAR-HULL- Ch15_LearningSpreadsheet_4b.3.volatility_ma: I was trying to work out the Std Dev formula: SQRT[ sum( squared x) / (n-1) - { (sum(x) ^ 2 ) / n*(n-1) } ] which is :- =SQRT(I4/(n-1)-F4^2/(n*(n-1))) in the sheet below. = SQRT [ .1603/ (120-1) - {(20.13/100 ) ^...

@David Harper CFA FRM Perfect !! :-) Thanks so much David !

Hi @ShaktiRathore Have a quick question here ...in this derivation of the Delta, you started with the Black Scholes formula for the Option Price:- c=Sexp(-qT)*N(d1)-X*exp(-rT)*N(d2) Isn't the formula c=S*N(d1)-X*exp(-rT)*N(d2) without the extra factor of exp(-qT) ......? We are not supposed to...

@ShaktiRathore This was indeed very helpful ! Thanks so very much !
