Answer:
Which stock has more systematic risk?
Which stock has more total risk?
Step-by-step explanation:
Systematic risk refers basically to the stock's risk compared to the market risk, when the stock's beta = 1, its systematic risk is the same as the market risk. In this case, since XOM has a larger beta than GM, then its systematic risk is higher.
To calculate which stock has a higher total risk I just multiply the stock's beta times the expected volatility, and GM's risk is higher.
