Maximum diversification benefit can be achieved if one were to form a portfolio of two stocks whose returns had a correlation coefficient of:

-1.0
+1.0
0.0
none of the above

Homework Answers

Answer #1

The correct answer is -1.0

Maximum benefit from diversification occurs when the correlation coefficient for pairs of stocks is minus one.

Diversification benefit - We should not invest our wealth in a single stock. We should invest in a portfolio. Whenever we combine two or more assets in a portfolio the risk gets reduced. The extent of risk reduction depends on correlation.
Correlation refers to the strength of liner relationship between two variables. It lies between -1 and +1. Lower the correlation, greater the benefit of diversification in the form of risk reduction. Therefore maximum benefit from diversification will occur when correlation coefficient is -1.

B. the two stocks are completely unrelated to one another. C. one of the two assets is a risk free asset. D. the returns of the two stocks move perfectly in sync with one another.

In a portfolio that contains two assets it is possible that there is no benefit to diversification from moving from a single asset to two assets. Why can this happen? Select one: a. It happens if returns on the assets in the portfolio are perfectly positively correlated. b. It happens if each of the assets is a common share. c. It happens if returns on one asset are negatively correlated with returns on the other asset. d. The statement is...

5. Diversification reduces the overall risk of a portfolio because of a factor called correlation. Explain how a stock with a return standard deviation of 20% can be combined with a stock with a return standard deviation of 13.2% and result in a portfolio whose return standard deviation is much lower than the standard deviations of the two individual stocks? What is it about the correlation coefficient between stocks which reduces portfolio risk?

Even if a portfolio of common stocks were divided into three subsets like “Small-Cap Stocks”, “Large-Cap Stocks”, and “International Stocks”, they would still exhibit a correlation of almost 100% so there would be little benefit to that type of diversification. True False

You are creating a portfolio of two stocks. The first one has a standard deviation of 21% and the second one has a standard deviation of 34%. The correlation coefficient between the returns of the two is 0.2. You will invest 38% of the portfolio in the first stock and the rest in the second stock. What will be the standard deviation of this portfolio's returns? Answer in percent, rounded to two decimal places (e.g., 4.32%=4.32).
