Diversification is one of the best ways to help manage risk and volatility in your investment portfolio.
A simpler way to think about diversification is not putting all of your eggs in one basket. As an investor, portfolio diversification generally means spreading your money across a mix of different asset classes (like stocks, bonds, and cash) and geographies. Each investor is unique and will likely have a different asset mix that matches their investment goals to align with how much risk they’re comfortable with.
Many ways to diversify

Different types of investments perform in different ways over time. When some rise in value, others may decrease or maintain their value. The concept of “correlation” measures the relationship between variables and is used by many portfolio managers and investors to select components of a portfolio that don’t generally behave in the same way at the same time. For example, when markets become uncertain due to an economic factor, equities may be seen as riskier and go down in value compared to cash-like investments. By diversifying, the goal is to get a smoother ride that is less volatile.
How much of your portfolio should you invest in each asset class?
The answer depends on your personal situation, risk tolerance, and your preferences as an investor. For example:

Remember, at a given time, any one asset class, region, sector, or style may lead the market while others lag. But in a diversified portfolio, a decline in one investment may be offset by growth in another. By building a diversified portfolio, you can help to limit the downside without giving up all of the upside. The chart shows market returns for an all-U.S. equity portfolio compared to a diversified portfolio over one, five, and 10-year periods. Notice that the longer you stay invested in the diversified portfolio, the less likely you would have been to experience a negative total return.
