Asset Class
A category of investments that share similar characteristics, risk profiles, and behavior in financial markets.
What is Asset Class?
An asset class is a grouping of financial instruments that share similar characteristics, are subject to the same regulatory framework, and tend to behave similarly in the marketplace. The major traditional asset classes are equities (stocks), fixed income (bonds), cash and cash equivalents, and real assets (real estate and commodities). Alternative asset classes include hedge funds, private equity, venture capital, and digital assets such as cryptocurrencies. Asset classes typically have different risk-return profiles, respond differently to economic conditions, and have low correlations with each other — which is why holding multiple asset classes through diversification reduces overall portfolio volatility. Asset allocation — deciding what percentage of a portfolio to hold in each asset class — is widely considered the primary driver of long-term investment returns.
Example
A 2024 target-date fund for a 35-year-old investor might hold: 70% equities (US and international stocks), 20% fixed income (US and global bonds), 5% real assets (REITs), and 5% cash equivalents. This multi-asset-class allocation is designed to grow aggressively while the investor has 30+ years to retirement, then automatically shift toward bonds and cash as the target date approaches.
