Under the MPYT/CAPM notes, there are several illustrated examples. Is there a workbook resource that is available for me to see how these tables are actually generated. Im having trouble figuring out how to generate the eqtn for covariance(port, market)

why is correlation included to solve the problem? I cant see anything in the notes when we multiply the two terms x correlation? Beta (i,M) = covariance(i, M)/variance(M) = 24%*15%*0.70/15%^2 = 1.12 <<- must know all of these steps! CAPM: E[R(i)] = Rf + Beta (i,M)*[R(M) - Rf] = 3% +...

The CAPM is a ex-ante single-factor model where the single-factor is the market's excess return: it says that we should expect an excess return that is proportional to the stock's beta, which is the stock's exposure to market's excess return, as measured by the stock's beta. Beta can be...
