QUESTION 4
A. Assume that you are a provider of portfolio insurance and that you are establishing a 3-year program. The portfolio you manage is currently worth 120 and you aim to provide a minimum return of 0%. The equity portfolio has a standard deviation of 30% per year and the risk-free rate is 2% per year. For simplicity, the portfolio pays no dividends.
