You work for XYZ company and you’ve been asked to evaluate a new project which has double the systematic risk of the company’s other projects.
You use the Capital Asset Pricing Model (CAPM) formula and input the treasury yield ##(r_f )##, market risk premium ##(r_m-r_f )## and the company’s asset beta risk factor ##(\beta_{XYZ} )## into the CAPM formula which outputs a return.
This return that you’ve just found is:
