Portfolio diversification is an investment strategy that spreads money across different asset classes, industries, and investments to reduce overall risk.
Rather than concentrating investments in a single asset or sector, diversification helps balance potential losses in one investment with gains in others.
Diversification helps manage investment risk. Markets and asset classes do not always move in the same direction at the same time.
By holding a mix of investments, investors can reduce the impact of poor performance from any single asset.
Diversification is considered one of the core principles of long-term investing.
Investors diversify by allocating funds across different types of investments, such as:
Diversification can also occur within asset classes by investing across sectors, industries, or geographic regions.
A well-diversified portfolio balances risk and potential return.
An investor might allocate a portfolio across U.S. stocks, international stocks, bonds, and real estate investment trusts (REITs). If one sector performs poorly, other investments may offset the losses.
Does diversification eliminate risk?
No. It reduces risk but cannot eliminate market risk.
How many investments are needed for diversification?
It depends on the investor’s strategy, but broader exposure generally improves diversification.
Do index funds provide diversification?
Yes. Many index funds hold hundreds or thousands of securities.
