You've probably heard the saying, "Don't put all your eggs in one basket." In investing, that idea is called diversification, and it's one of the most important principles for building long-term wealth. Diversification won't eliminate risk entirely, but it can help reduce the impact of any single investment performing poorly — and make your journey toward your goals smoother.

At its core, diversification means spreading your money across different types of investments that don't all move in the same direction at the same time. When one part of your portfolio struggles, another part may hold steady or even grow. Over time, this balance can help reduce sharp swings in your overall portfolio value.

Diversifying across asset classes

The first layer of diversification is across asset classes, such as stocks, bonds and cash. Stocks generally offer higher growth potential but come with more volatility. Bonds tend to provide steadier income and can cushion a portfolio during stock market downturns. Cash and cash equivalents offer stability and liquidity. The right mix depends on your goals, time horizon and comfort with risk.

Diversification also matters within each asset class. Rather than owning just a few companies, you can spread stock investments across many businesses, industries and company sizes. Including international investments adds another layer, since different economies don't always rise and fall together. Bonds can be diversified by issuer, credit quality and maturity.

Diversification isn't about owning more — it's about owning a smarter mix.

For many investors, broad-market index funds and exchange-traded funds offer an easy and cost-effective way to diversify. A single fund can hold hundreds or even thousands of securities, giving you wide exposure without having to research and buy each investment individually. Target-date funds go a step further by automatically adjusting their mix as you approach a chosen date.

It's important to remember that diversification is not a one-time task. As markets move, your portfolio can drift away from its original balance. Rebalancing — periodically selling some investments that have grown and adding to those that have lagged — helps you maintain the level of risk you're comfortable with.

Building a portfolio that fits you

There's no single "perfect" portfolio. The right diversification strategy reflects your personal goals, how long you plan to invest and how you'd feel during market ups and downs. Reviewing your investments regularly keeps your plan aligned with your life.
