Design an Excel financial model that can help to evaluate this investment plan. Marks will be allocated for the presentation and clarity of your model (e.g., if there are clear headings, clear arrangement for input cells, appropriate use of colors, have some degree of flexibility, generate warning messages for wrong user inputs, etc.). The Excel financial model should enable you to consider the investment plan and answer the following questions:

Problem 1: For each stock, show the daily stock returns.

Problem 2: Based on the responses in part (1), calculate the average daily stock returns and standard deviation for each stock.

Problem 3: Calculate the correlation of daily stock returns between each pair of stocks.

Problem 4: Suppose that you invest 20% in Singapore Airlines Limited, 50% in Qantas Airways Limited and 30% in Cathay Pacific Airlines. Calculate the portfolio expected return, variance and standard deviation.

Problem 5: How does the expected return and standard deviation change if you decide to invest 30% in Singapore Airlines Limited, 60% in Qantas Airways Limited, and 10% in Cathay Pacific Airlines? Explain your answers.

Problem 6: Find the weights of Singapore Airlines Limited, Qantas Airways Limited and Cathay Pacific Airlines that will provide a daily return of 0.01% with the lowest level of risk.

Problem 7: Plot a scatter diagram showing the portfolios from parts (4), (5) and (6), with the X-axis displaying standard deviation and the Y-axis displaying daily returns.

Problem 8: If the daily risk-free rate is 0.1%, estimate the Sharpe ratio for the portfolios mentioned in parts (4), (5) and (6) and highlight the highest Sharpe ratio using conditional formatting.
