Which of the following statements about beta is correct? 1 options: A portfolio that contains 100 high-beta stocks will not be riskier than a portfolio containing 100 low-beta stocks. A stock’s standard deviation of returns is a measure of the stock’s stand-alone risk, while its beta measures its unsystematic risk. If the returns on a stock vary widely, then its standard deviation is large, and as a result, the stock will also have a high beta coefficient. A stock that is perfectly positively correlated with the market cannot have a beta coefficient equal to 1.0.
