He estimates he will need $500,000 in expenses at that time for his daughter's education expenses. His financial advisor presents him with a 5year structured deposit A. It will earn 1% per annum for the first two years, stepping up to 2% in the 3rd year and 3% in the last 2 years. (a) How much must he set aside today to be able to have $500,000 in five years' time? Calculate the average annual return he will be earning if he invests in A. (5 marks) (b) His financial advisor presents another structured deposit, B, which has the same return profile but whose return depends additionally on the performance of 3 stocks X, Y, and Z. He will get an additional 5% return at maturity if the prices of all 3 stocks are 10% higher than today. How much does Martin have to pay for this second structured deposit, assuming that all of the 3 stocks are 10% higher at maturity? He still receives $500,000 at maturity. Calculate the average annual return of investment B. In this case, which investment would you recommend, A or B? Justify your choice
