The Capital Asset Pricing Model
One common use of the CAPM is as a descriptive tool where the following equation
E(r) = rf + ß [ E(rm) – rf ]
is interpreted as a forecast of expected asset returns.
The coursework project
The purpose of the project is to test validity of the CAPM using monthly close data. The steps in the test are as follows:
1. Determine a candidate for the market portfolio m by picking a stock index of your choice. You can pick an index of your choice. Then choose a minimum of 15 stocks in that market for the purpose of the test. Make sure that your set of stocks doesn’t overlap with those of any other group. Then download the daily historical prices from 1st of Jan. 2007 to 1st of Sep. 2015.
2. For each of the assets making up the index, determine the beta by linear regression.
3. Regress the mean returns of the assets on their respective betas, .
4. If the CAPM in its interpretation above holds, then the equation obtained in step 3 should be the Security Market Line. To evaluate whether this is the case
a. Compare to the average risk-free rate over the period, which is what it should correspond to.
b. Compare to what it should correspond to: , where is the average risk-free rate over the period.
c. Calculate and the t-statistic of the regression to evaluate its statistical significance.
5. Analyse, reflect on, and discuss your results. Critically analyse the theory in light of the results. Formulate your findings.
6. Create relevant charts to illustrate your findings.
