Diversification is one of the most widely used and often misunderstood concepts in investing. While it’s commonly associated with simply “not putting all your eggs in one basket,” the real benefit runs deeper. At its core, diversification helps reduce the impact of risks that are unique to individual investments, while allowing portfolios to capture broader market returns. Just as important, it helps smooth the experience of investing, making it easier to stay disciplined through periods of uncertainty. When investors understand both the theoretical and behavioral advantages, diversification becomes less of a rule of thumb and more of a foundational principle in building a resilient portfolio.
