1. ### Hull Risk Management Ch10 - EOC-QUESTIONS 10.21 and 10.5

@QuantMan2318 @David Harper CFA FRM I am a bit rusty on Integrals and so have a follow up question V(t) = V(L )+ e^ -Gamma*T [ V(0) - V(L) ] So, I/T * Integral [ V(t) ] = 1/T * Integral { V(L )+ e^ -Gamma*T [ V(0) - V(L) ] } Now, Integral { V(L )+ e^ -Gamma*T [ V(0) - V(L) ] } = Integral...
2. ### Hull Risk Management Ch10 - EOC-QUESTIONS 10.21 and 10.5

@QuantMan2318 @David Harper CFA FRM Have one more follow up question on this one.. So, the Variance for a future time period is given by :- ()=+−[()−] -------Equation 1 To find the estimate of implied volatility at time T we take the average of the above (Average volatility) which is the...
3. ### Hull Risk Management Ch10 - EOC-QUESTIONS 10.21 and 10.5

Thanks again so much @QuantMan2318 - Think I got it this time around As Gamma is a small no, (Gamma)^2 and Higher Powers of Gamma and so on are negligible and can be approximated to 0. So by the Taylor Series Expansion of Ln ( 1+ x) approximates to x with the higher powers of x being almost...

Thanks so much @QuantMan2318 - thought I almost understood this - and then hit this hurdle ...:confused::confused: As you rightly pointed out: Given that Gamma = [ 1 - (Alpha + Beta ) ] , How is Gamma = LN [ 1 / (Alpha +Beta ) ] ...? :confused::confused::(

8. ### F- Statistic Formula Variations

Hi, @David Harper CFA FRM had indicated in a thread that -" The general form of the F-statistic is F[numerator df, denominator df] = (ESS/df)/(RSS/df) " F -Statistic is also expressed as = {Sum Of Squares BETWEEN / df-BETWEEN } / { Sum Of Squares WITHIN / df-WITHIN } => This expression of...

13. ### Hull Chapter 7: Swaps

Got it :):):cool::cool: Thanks so much @David Harper CFA FRM - I was missing the key insight that the floating rate is observed at the beginning of the (six-month, in this case) period, but paid at the end of the (six-month) period - that helped a lot :):)
14. ### R19.P1.T3.HULL Ch7 Currency Swap Valuation XLS

Thanks @Nicole Seaman for the links above - I did check them out... I was trying to use the same techniques to calculate the Prices of the 2 Bonds for the Currency Swap Valuation- but the answer I am getting is way different than if worked out by hand somehow....and so I was trying to see if I...
15. ### Hull Chapter 7: Swaps

Hi- I was revisiting this example and have a follow question- For the Floating Rate Cash Flows, the Problem statement states that the 6-Month LIBOR at the Last Payment Date =10.2 % " Last-Payment Date " with respect to which point in time..? Instead of T= .25/3 Months, Last Payment Date could...
