Astock with a beta of 0.8 has an expected rate of return of 12%. if the market return this year turns out to be 5 percentage points below expectations, what is your best guess as to the rate of return on the stock?

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%.
