3. Compute excess returns for the market, i.e. market risk premia, as R = Rm - Rrf, where Rm is the return on the All Ords computed in question 1, and Rr represents the monthly return on the 30 day bank accepted bill rate. Also compute excess returns for IAG and MQG as follows RAG = RIAG-Rrf and RMQG = RMQG - Rr. Use the 1/2/2002 - 1/2/2020 time period. (2 marks) 4. Obtain CAPM betas for both IAG and MQG using excess returns by estimating the following regressions RIAGIAG+BIAGR + UIAG Rhc = amc + BuocR +uMoG = where UAG and UMQG are the random error terms.
