You are trying to determine the cost of equity of your private company. You are looking at the beta of Company A which is 1.5 but Company A is 10x larger than yours even though you sell many of the same products. The beta of Company B is 4.0 but it is closer to the size of your company and it also sells many of the same products that you do. Given that the risk-free rate is 3.0% and the expected return of the market is 20% what is the cost of equity for your private company.
