Hi David, this is from your Study Notes page 21 on Allen. If K=100 how can there data points which are 165 periods ago? I thought we have 250 data points and just look back at the 100 recent and these 100 recent data points we sort descending and do our computations on them. So the oldest...

Thank you David.:)

Hi David, can I only have one of both: Lease rate or convenience yield in the exponent? Because if I lease it i can't take the advantage of the convenience yield? Or do I have always to consider if exists: lease rate and convenience yield and storage cost? 1. r+u-lease-convenience 2. r+u-lease...

Hi David, yes that's perfect. Thank you for your "short enough" help.;-) You are doing a great job. Regards

Hello David, just a basic question, but i don't get it (a short answer would be enough): Assuming the 1 year future price is 900 $. Shorting the future. What is the meaning of the 900 $? I dont't understand the difference between the "price I will receive at delivery/expiry " and the "quoted...

THX a lot. The forum is really helpful.

Hello, i have the following question: 1. The joint probability for two independent events is defined as: P(A and B)=P(A)xP(B) 2. Why is not P(High=20%)xP(Increase=40%)=P(Increase and High=10%). Or should it be and only the example is wrong? Can anybody explain it please? I wish all...

Question set Miller Probability 201.4 "The simplified standard deviation = ..." I assume the sqrt is missing here to get to a result of 4.0? Regards

Study Notes APT page 9: "Let the factor exposures of a well-diversified portfolio, P, be given by its betas, BetaSubp1 and BetaSubp1" Should it be: Let the factor exposures of a well-diversified portfolio, P, be given by its betas, BetaSubp1 and BetaSubp2"? Regards

Hi all, just one point regarding the use of the term "excess return" which confuses me: In the Notes for CAPM_Elton, page 5: Excess return is defined as RsubM minus RsubF (I understand) In the Notes for APT_Bodie, page 8: Excess return on portfolio is defined as E(RsubA) + BetasubA times F I...
