What Is a Mutual Fund?
A mutual fund is a pooled investment vehicle that collects money from multiple investors to buy a diversified portfolio of stocks, bonds, or other securities. Each investor owns shares of the fund, which represent a portion of the holdings.
Key Characteristics of Mutual Funds
- Pooled Investments – Money from many investors is combined.
- Professional Management – Fund managers make buy/sell decisions.
- Diversification – Reduces risk by spreading investments across assets.
- Liquidity – Investors can buy or sell shares at the fund’s Net Asset Value (NAV) at the end of each trading day.
How Mutual Funds Operate: Step by Step
1. Investors Buy Shares
When you invest in a mutual fund, you purchase shares at the Net Asset Value (NAV), calculated daily after market close.
NAV = \frac{Total\ Assets - Total\ Liabilities}{Number\ of\ Outstanding\ Shares}Example:
- A fund has $100 million in assets, $5 million in liabilities, and 10 million shares.
- NAV = \frac{100M - 5M}{10M} = \$9.50\ per\ share
2. The Fund Manager Invests the Pooled Money
The fund manager allocates capital based on the fund’s strategy:
- Equity Funds → Stocks
- Bond Funds → Fixed-income securities
- Balanced Funds → Mix of stocks and bonds
3. Returns Are Generated
Investors earn returns through:
- Dividends/Interest – Paid out or reinvested.
- Capital Gains – Profits from selling securities.
4. Investors Redeem Shares
When you sell, the fund pays you the current NAV (minus fees, if applicable).
