A

Cov (rj, rm)/ std dev^2m

25

A

A higher sensitivity to the market (and a beta value lower than 1 indicates lower sensitivity)

26
Q

How do you calculate the beta value of a portfolio?

A

It is a weighted average of all the betas

Bp = (Bj x W1) + (Bn xW2) + (Bc x W3)

That the expected return of an asset is equal to the risk free rate of return plus a market premium

A

That the asset moves in the same direction and at the same rate as the market
