When considering what investments to include in an investor’s portfolio construction process, it’s important to consider their risk tolerance. A portfolio’s risk level not only depends on its individual securities but also how these securities interact with each other—hence portfolio diversification. The more asset classes in a portfolio, the more likely it is to reduce market volatility, but also potentially returns. Though a 60/40 portfolio enjoyed about 15% gains last year, the macroenvironment is different this year. With 2025 presenting economic and market uncertainty, portfolio diversification is ever critical to withstand any market condition.
