Which investment type best describes a portfolio that includes multiple investments managed together?

• A. Stocks.
• B. Bonds.
• C. Mutual funds.
• D. Savings accounts.

Answer: (C)

Diversification through a single, professionally managed investment vehicle is what this is about. A mutual fund fits this description because it pools money from many investors and buys a diversified mix of assets—stocks, bonds, or other securities—within one fund. A fund is run by a manager who selects holdings and makes ongoing decisions, so you own shares of the fund rather than individual securities. This setup gives you exposure to multiple investments in a single, managed portfolio, making it easier to achieve diversification without buying many different assets yourself.

Stocks are individual shares of a single company, so they don’t by themselves represent a diversified portfolio. Bonds are debt instruments, often part of a portfolio but not a single product that aggregates multiple investments. Savings accounts are cash deposits with little to no diversification or active management.
