Investment Analysis

Asset Class

A group of investments with similar behavior, risk, and regulatory profiles (e.g., stocks, bonds, cash).

Also known as: asset classes, investment class

What You Need to Know

An asset class is a broad category of investments that respond similarly to market conditions. Each class has its own expected return, volatility, and role inside a portfolio.

Core Asset Classes:

  • Stocks (Equities): Highest growth potential but also highest volatility
  • Bonds (Fixed Income): Provide income and stability; prices move opposite interest rates
  • Cash & Cash Equivalents: Very safe, low return (savings accounts, money markets, T‑bills)
  • Real Assets: Real estate, commodities, infrastructure that hedge inflation

Why Asset Classes Matter:

  • Drive 90%+ of portfolio risk/return
  • Guide diversification decisions
  • Help match investments to time horizon
  • Make rebalancing rules clearer (sell overweight classes, buy underweight)

Example: A 60/40 portfolio holds 60% stocks and 40% bonds. If stocks rally, the asset class weighting shifts—triggering a rebalance to restore balance.
