Mutual funds are one of the most accessible and popular investment options for individuals looking to participate in the financial markets without the need to select individual securities on their own. Essentially, a mutual fund gathers money from many investors and invests it in a broad mix of stocks, bonds, or other securities managed by professional fund managers. This pooled approach offers diversification, professional oversight, and lower investment minimums compared to buying individual securities.

How Mutual Funds Work

When you invest in a mutual fund, you buy shares or units of that fund. The mutual fund then uses the combined capital of all investors to purchase a diversified portfolio of assets. The value of each share, known as the Net Asset Value (NAV), is calculated daily after markets close by dividing the total value of the fund’s assets minus liabilities by the number of outstanding shares. As the investments perform — whether they increase or decrease in value — the NAV and subsequently your investment’s value will also fluctuate.

Types of Mutual Funds

Mutual funds come in various types, each catering to different investor goals and risk tolerances:

  • Stock Funds (Equity Funds): Invest mainly in stocks seeking growth or income. Subcategories include growth funds, value funds, income funds, and sector-specific funds like technology or healthcare.
  • Bond Funds (Fixed-Income Funds): Invest in bonds and debt instruments, typically offering regular income with generally lower risk than stock funds. These include government bonds, corporate bonds, high-yield bonds, and municipal bonds, the latter often providing tax advantages What are Municipal Bonds?.
