Suppose CAPM works, and you know that the expected returns on Google and IBM are estimated to be 16.75% and 12.50%, respectively. You have just calculated extremely reliable estimates of the betas of Google and IBM to be 1.50 and 0.93, respectively. Given this data, what is a reasonable estimate of the market risk-premium in percentage (the average/expected difference between the market return and the risk-free rate)?
