What are Mutual Funds?
A mutual fund pools money from thousands of investors and invests it in a diversified portfolio of stocks, bonds, or other securities. A professional fund manager makes the investment decisions on behalf of all investors.
When you invest in a mutual fund, you buy units. The price of each unit is called Net Asset Value (NAV) — calculated daily by dividing the total value of the fund's portfolio by the number of outstanding units. If the portfolio's value rises, NAV rises, and vice versa.
Types of Mutual Funds by asset class: Equity funds invest primarily in stocks — suitable for long-term wealth creation (5+ years). Debt funds invest in bonds and fixed-income instruments — lower risk, suitable for 1-3 year horizons. Hybrid funds mix equity and debt. Liquid funds invest in very short-term instruments — ideal for parking emergency funds.
Equity funds are further classified by market cap: Large-cap funds invest in the top 100 companies (stable, lower risk). Mid-cap funds invest in companies ranked 101-250 (higher growth potential, more volatile). Small-cap funds invest in companies ranked 251+ (highest potential, highest risk).
The Expense Ratio is the annual fee charged by the fund as a percentage of assets. A 1% expense ratio means Rs 1 of every Rs 100 is paid to the AMC every year. Index funds have much lower expense ratios (0.1-0.2%) than actively managed funds (0.5-2.5%). Over 20-30 years, this difference compounds dramatically.
SEBI mandates that all mutual funds display 5-year rolling returns, risk-o-meter (risk level), benchmark comparison, and expense ratio on their fact sheets. Always check if a fund is beating its benchmark consistently over 3-5 years — if not, an index fund is a better choice.
