The correct option is this Both A and B.
In Finance MCQs, the coefficient of variation (CV) is a very important concept used to evaluate the combined effect of risk and return on an investment. It is considered a risk-adjusted performance measure because it does not only look at volatility (risk) or expected return separately, but instead examines how much risk is taken to earn a specific level of return. That is why when a question asks whether CV measures both risk and return, the correct answer is Both A and B.
The coefficient of variation is calculated using the following formula:
CV = Standard Deviation ÷ Expected Return
CV = σ ÷ μ
Here, standard deviation (σ) represents total risk or volatility, while expected return (μ) represents the average return anticipated from an investment. By dividing risk by return, the CV expresses how much risk an investor must bear per unit of return. This makes it a relative measure rather than an absolute one.
One of the key reasons why CV is important in finance is that standard deviation alone only measures absolute risk. For example, suppose Investment A has a standard deviation of 12% and Investment B has a standard deviation of 15%. If we only compare risk, Investment A appears safer. However, if Investment A offers an expected return of 8% while Investment B offers 20%, the situation changes. When we calculate the CV, we may find that Investment B provides better risk-adjusted performance despite its higher volatility. This demonstrates why CV incorporates both risk and return.
The coefficient of variation is particularly useful when comparing investments with different scales of returns. If two securities have different expected returns, comparing only their standard deviations can be misleading. CV standardizes the risk measure relative to return, allowing fair comparison. A lower CV indicates that an investment provides more return per unit of risk, making it more efficient and attractive to rational investors. On the other hand, a higher CV suggests higher relative risk for the same level of return.
It is also important in Finance MCQs to differentiate CV from related terms. Risk alone refers to variability in returns, typically measured by standard deviation or variance. Return alone reflects profitability but ignores uncertainty. Deviation is simply the difference between actual and average values and does not provide a performance measure. Only the coefficient of variation combines risk and return into one meaningful metric, which is why the correct option is Both A and B.
From a practical finance perspective, the CV is widely applied in portfolio management and investment analysis. Investors use it to choose between mutual funds, stocks, and other securities when expected returns differ significantly. In capital budgeting, managers may compare projects with varying levels of expected profitability and uncertainty using CV to select the most efficient option.
In competitive exams such as CFA, MBA Finance, CSS, PMS, and banking tests, students are often asked to calculate CV, interpret its value, or rank investments based on risk-adjusted performance. Understanding the coefficient of variation strengthens conceptual clarity regarding the risk-return tradeoff, which is a foundational principle in finance.
In conclusion, the coefficient of variation measures the relative impact of both risk and return on an investment. It provides a standardized, risk-adjusted comparison tool that helps investors and finance professionals make informed decisions in both exam settings and real-world financial markets.
