Can someone please explain to me why in questions 44 and 47 we dont divide by the beta of futures contract when calculating the # of contracts required? Question 44: We create synthetic stock index from cash, but we assume that futures beta of the European broad based equity is equal to 1. The vignette tells you its 0.8, why not use it? Question 47: We create synthetic cash from equities, but we assume that futures beta of the mid-cap equities is equal to 1. The vignette tells you its 1.29, why not use it? Thanks
