Answer:
16.15%
Step-by-step explanation:
Required rate of return is the rat that a investor expect for investment in a specific stock. It also account for the risk associated with that stock.
As per given data
Inflation rate = 4.2%
Real Risk free rate = 2.5%
Risk free rate = 4.2% + 2.5% = 6.7%
Market Risk Premium = 4.5%
Beta = 2.1
To calculate the required rte of return we will use the CAPM formula as below
Required rate of return = Risk free rate + Beta ( Market Risk Premium )
Required rate of return = 6.7% + 2.1 ( 4.5% )
Required rate of return = 16.15%
