In contrast, if the market return decrease by 10%, the return of the portfolio of beta +1.00 would also decrease by 10%. From the calculation above, portfolio A has a greater than 1.00 beta. This means that portfolio A is a high risk and high return portfolio. Conversely, portfolio B has a beta of less than 1.00.
