Portfolio returns. The Capital Asset Pricing Model is a financial model that assumes returns on a portfolio are normally distributed. Suppose a portfolio has an average annual return of 10.9% (i.e. an average gain of 10.9%) with a standard deviation of 24%. A return of 0% means the value of the portfolio doesn't change, a negative return means that the...

Portfolio returns. The Capital Asset Pricing Model is a financial model that assumes returns on a portfolio are normally distributed. Suppose a portfolio has an average annual return of 16.5% (i.e. an average gain of 16.5%) with a standard deviation of 32%. A return of 0% means the value of the portfolio doesn't change, a negative return means that the...
