Final answer:
The stock's required rate of return as determined by the capital asset pricing model is influenced by the risk-free rate of return, the market risk premium, and the stock's beta.
Step-by-step explanation:
The stock's required rate of return as determined by the capital asset pricing model is influenced by all of the above. The required rate of return takes into account the risk-free rate of return, the market risk premium, and the stock's beta. The risk-free rate of return is the rate of return on a risk-free investment, such as a government bond, which serves as a baseline for expected returns. The market risk premium is the additional return required by investors for taking on the risk of investing in the stock market. The stock's beta measures its sensitivity to market movements, with high beta stocks being more volatile and riskier than low beta stocks.
