The benefits of diversification occur as long as the investments in a portfolio are not perfectly positively correlated. Select one: a. True b. False
The correct answer and explanation is:
The correct answer is a. True.
Explanation:
Diversification is a strategy used to reduce risk by investing in a variety of assets, which are typically not correlated or are weakly correlated with each other. When investments are not perfectly positively correlated, the performance of one asset in a portfolio will not necessarily move in the same direction as the others, thus reducing overall portfolio risk.
If the assets are perfectly positively correlated, meaning their returns always move in the same direction, diversification will not be effective. In such a case, all the investments in the portfolio will experience the same risk at the same time, and the risk of the entire portfolio would remain high. Therefore, for diversification to be effective, the investments must not be perfectly positively correlated. Ideally, they should have low or negative correlations, meaning that when one asset performs poorly, others may perform better, thereby balancing the portfolio’s overall risk.
For example, if one stock in a portfolio declines due to a sector-specific issue, other stocks in different sectors may not be affected in the same way, thus mitigating the loss. Similarly, investing in different asset classes like stocks, bonds, or real estate can also offer protection against specific risks tied to any one type of asset.
Thus, the key to effective diversification is the selection of assets whose returns do not move in tandem, allowing the portfolio to experience smoother overall performance over time. The greater the lack of correlation between the assets, the more risk reduction occurs, and the higher the potential for positive returns across the portfolio in the long run.
