Question
2. My. Sy wants to find a new investment for his portfolio. He is looking for a safe investment that provides stable returns. He considers the following options for investment: Stocks: He was offered a stock of ABC Corp. It is a mature company with strong operational and financial performance. The volatility (standard deviation or sd) of the stock is 10% and the expected return (mean) is 14% Exchange-Traded Fund(ETF): The ETF with strong financial performance offers an expected return (mean) of 13% with a volatility (standard deviation or sd) of 7% Bonds: Bonds with excellent credit ratings offer an expected return of 3% with 2% volatility. Question: What do you think is the most suitable investment opportsdsity for Mr. Sy? Why? Show your solution. Note: In order to select the most suitable investment opportunity, you have to calculate the coefficient of variation for each option using volatility 100% cv = (- where volatility is the standard deviation and expected return is the expected return/ mean Remember: In finance, the coefficient of variation allows investors to determine how much volatility, or risk, is assumed in comparison to the amount of return expected from investments. The lower the coefficient of variation, the better the investment opportunity.
