What is portfolio diversification primarily aimed at mitigating?

Portfolio diversification is primarily aimed at mitigating risk. By spreading investments across a variety of asset classes, industries, or geographical locations, diversification helps reduce the impact that a poor performance in any single investment can have on the overall portfolio. This strategy capitalizes on the principle that different assets do not always move in the same direction or to the same degree under varying market conditions.

For instance, when some investments are experiencing losses, others may be gaining, leading to a more stable overall portfolio performance. It creates a cushion against significant losses and helps investors achieve a more predictable return on their investments over time, which is a key objective in portfolio management.

While operational efficiency, investment returns, and market fluctuations are important concepts in portfolio management, they are not the primary focus of diversification. The essence of diversification is to provide a protective measure against risk, ensuring that the portfolio is resilient in the face of uncertainty and varying market conditions.
