The Investment Lineup
In Requirement 4, you learned the principles of investing — risk, return, diversification, and compound interest. Now it is time to meet the specific tools. Think of these six investment types as different tools in a toolbox. Each one has a purpose, and smart investors use a combination of them.

5a: Common Stocks
When you buy a stock, you are buying a tiny piece of ownership in a company. If the company does well and grows, your piece becomes more valuable. If the company struggles, your piece loses value.
How stocks make you money:
- Price appreciation: You buy a stock for $50, and it grows to $75. You can sell it for a $25 profit.
- Dividends: Some companies share profits with shareholders by paying dividends — regular payments (usually quarterly) for each share you own.
The risk: Stock prices go up and down daily, sometimes dramatically. A single company’s stock can lose most of its value if the company has serious problems. That is why diversification — owning many different stocks — is so important.
5b: Mutual Funds
A mutual fund pools money from many investors and uses it to buy a collection of stocks, bonds, or other investments. A professional fund manager decides what to buy and sell within the fund.
Why mutual funds are popular:
- Instant diversification: Instead of buying one stock, you own a piece of dozens or hundreds of investments
- Professional management: A fund manager does the research and makes decisions
- Accessibility: You can invest with relatively small amounts of money
The trade-off: Mutual funds charge fees (called an expense ratio) that reduce your returns. Index funds — a type of mutual fund that simply tracks a market index like the S&P 500 — tend to have much lower fees and often outperform professionally managed funds over long periods.
5c: Life Insurance
Life insurance is unusual on this list because it is primarily a protection product, not a pure investment. When someone buys a life insurance policy, they pay regular premiums. If they die while the policy is active, the insurance company pays a lump sum (called a death benefit) to the person’s beneficiaries — usually their family.
Why it is listed as an investment: Some types of life insurance (called whole life or universal life) include a savings component that builds cash value over time. You will learn more about the differences between whole life and term life in Requirement 6.
Who needs life insurance: Primarily people whose families depend on their income. If a parent earns the family’s main income and dies unexpectedly, life insurance helps the family pay bills, mortgages, and living expenses.
5d: Certificate of Deposit (CD)
A certificate of deposit (CD) is like a savings account with a lock on it. You deposit a fixed amount of money for a set period — called the term — and in return, the bank pays you a higher interest rate than a regular savings account.
How CDs work:
- You choose a term (common terms: 3 months, 6 months, 1 year, 2 years, 5 years)
- The bank pays a fixed interest rate for the entire term
- When the term ends (called maturity), you get your money back plus the interest earned
- If you withdraw early, you usually pay a penalty
When CDs make sense: When you have money you know you will not need for a specific period and you want a guaranteed, predictable return with virtually no risk.
5e: Savings Account
A savings account is the most basic and accessible place to keep money. You deposit money at a bank or credit union, earn a small amount of interest, and can withdraw your money whenever you need it.
Key features:
- FDIC insured (up to $250,000 per depositor, per bank) — your money is protected even if the bank fails
- Liquid — you can access your money at any time
- Low return — interest rates are typically lower than other investments
- No risk — your balance will never go down (the interest rate might change, but your principal is safe)
Types of savings accounts:
- Regular savings: Basic account, lowest interest rate
- High-yield savings: Online banks often offer significantly higher rates because they have lower overhead costs
- Money market accounts: Slightly higher rates, may require a higher minimum balance
5f: U.S. Savings Bond
A U.S. savings bond is a loan you make to the federal government. You buy the bond, and the government promises to pay you back with interest after a certain period.
Two main types:
- Series EE bonds: Guaranteed to double in value over 20 years. They earn a fixed interest rate.
- Series I bonds: Earn a combination of a fixed rate plus an inflation rate that adjusts every six months. These protect your money from losing purchasing power due to inflation.
How to buy them: U.S. savings bonds are purchased online through TreasuryDirect.gov. You can buy them for as little as $25.
Putting It All Together
Here is how these investments compare:
| Investment | Risk Level | Liquidity | Typical Return | Best For |
|---|---|---|---|---|
| Savings account | Very low | High | 1–5% | Emergency fund, short-term goals |
| CD | Very low | Low (locked in) | 2–5% | Money you will not need soon |
| U.S. savings bonds | Very low | Low (penalties if cashed early) | 2–5% | Long-term, safe growth |
| Mutual funds | Medium | Medium | 7–10% (historical average) | Long-term growth, diversification |
| Common stocks | High | High | Varies widely | Long-term growth (with research) |
| Life insurance | Low (cash value) | Low | Varies | Family protection + slow growth |
