The objective of this model is to maximize the expected return of the portfolio and to increase the level of risk. The expected return and the standard deviation are changing in a specific way. The ways in which they are being added do vary from other portfolio securities. This model is specified for those investors who are very desperate to take the risk regarding the business choose portfolio A, whereas the investors who are risk-averse choose portfolio B.

Having a risk-free asset the investors do not have any efficient frontier that they can perform to do. In order to keep the market equilibrium, it has stated that the quantity supplied is equal to the quantity demanded. So the investors can make a combination for the market portfolio and as well as for the risk-free asset. If the CAPM has an accurate description then there is a positive relationship that can be observed by the investors which compensates for the bearing of the asset.
