Answer:
The correct answer is: The expected rate of return for the stock would be around 7%.
Explanation:
The Beta coefficient is a numeral measure that portraits the volatility of a stock compared to the overall market performance. If a stock's beta is closed to the numerical value one (1) it implies it is highly correlated to the price movement of the overall market.
In that case, if a stock's beta is 0.8 it implies it follows the market price movements. If the stock expected rate return is 12% but the market return turns out to be 5% points below expectations, it means the stock's return would end up being around 7%.
