CAPM and Portfolio Analysis
Task 1
a. Using the first three years of data (October 2009 to October 2012) regress the monthly log-normal returns of the five companies against the log-normal returns
for the FTSE All-Share Index. (You can use the Regression function in Excel Data Analysis’)
(15 per cent)
b. Briefly analyse the relationship of the individual security performances to the performance of the FTSE All-Share, focusing in particular on the alpha, beta
and R2 estimates.
(10 per cent)
Task 2
Assume that at the start of October 2012 you owned an equally weighted portfolio of the four companies.
a. Calculate the actual annual return on the FTSE All-Share Index for both years starting from October 2012 and October 2013.
(10 per cent)
b. Take the FTSE All-Share returns as market returns and, using the alpha and beta sample estimates generated in Task 1, calculate the expected annual returns for
each asset and for the portfolio using the Single Index Model approach.
(10 per cent)
Task 3
a. Calculate the actual annual returns for each company and for the portfolio over the period from October 2012 to October 2014.
(10 per cent)
b. Compare the actual and expected returns and comment on the scale of the abnormal returns over the two-year period from October 2012 to October 2014 for both
the individual companies and the portfolio.
(15 per cent)
Task Four
Assess how well the model performed in predicting the actual return on the portfolio, given that it was based on a restricted sample of historical data.
