Which of the following statement is correct? High beta stocks move more than the market and low beta stocks move less than the market, both in the same direction as the market. The coefficient of variation (CV) measures relative risk by relating the standard deviation to the beta. The risk/return tradeoff states that financial decisions that subject stockholders to less risk must offer a higher expected return. Whenever we want to compare the risk of investments that have different means, we use the standard deviation. All the answers are incorrect
