Question 2 (30 Marks) (a) You want to estimate the daily value at risk (VaR) for the stock returns of a public firm currently valued at $800 million. Using its stock returns data for the past 2 years (ordered in decreasing order, from highest daily return to lowest daily return), you have the daily stock returns as follows: 24.73%, 19.25 % 17.83 %, 15.87 %, 14.56 %, 13.73 %, 12.25 % 11.83 %, 10.87%, 8.56%, -9.41 %, -10.43%, -11.91%, -12.41%, -13.43%, -14.28%, -15.76%, -16.67%, -17.28%, -18.76%, -20.67%. 7.79% Estimate the daily VaR and expected shortfall (ES) of the firm's stock return at the 98% confidence level using the historical simulation method. Assume we have 2 years' trading data for the bank and there are 250 trading days in a year (i.e., 500 trading days in total). Which one should be preferred to use by a risk manager? Why? (15 Marks) (b) Imagine you are a risk manager for the video-sharing mobile application TikTok. You have identified 9 risks within the company which are coded from R001 to R009 as shown in the table below. After the risk workshops with the relevant experts, you have assigned the risk impact and probability of occurrence to each risk in a scoring system based on the ordinal scale. You want to prioritise these risks and make action plans accordingly. Assume all the risks are realistic and relevant to the company. A larger value in the ordinal scale indicates a higher level of risk impact (probability of occurrence).
