Asset Allocation: The Most Important Investment Decision You'll Make

Asset allocation is the practice of dividing your investment portfolio among different asset categories, such as stocks, bonds, and cash. It is widely considered the most important factor in determining the overall risk and return of your portfolio—even more than the specific investments you choose.

The Core Asset Classes

  1. Stocks (Equities): Represent ownership in a company. They offer the highest potential for long-term growth but also come with the most volatility (risk).
  2. Bonds (Fixed Income): Are essentially loans you make to a government or corporation. They are generally less risky than stocks and provide a steady stream of income.
  3. Cash & Cash Equivalents: Includes savings accounts, money market funds, and short-term CDs. They are very low-risk but also offer the lowest potential returns.

The goal of asset allocation is to create a mix that aligns with your financial goals, risk tolerance, and time horizon.

How to Choose Your Asset Allocation

Your ideal mix will change over your lifetime. Here are two common rules of thumb:

  • The 110 Rule: A simple guideline is to subtract your age from 110. The result is the percentage of your portfolio you should allocate to stocks. For example, a 30-year-old might have 80% in stocks (110 - 30) and 20% in bonds.
  • Time Horizon: The longer you have until you need the money (e.g., for retirement), the more risk you can afford to take. A young investor should have a higher allocation to stocks for growth. As you approach retirement, you should shift more towards bonds and cash to preserve your capital. As Fidelity explains, your personal financial situation and risk tolerance are also key factors.
