What is the difference between stocks, mutual funds and ETFs?

A stock is a share in one company. A mutual fund and an ETF are both baskets holding many investments — they differ mainly in how you buy and sell them, not in what they contain. **Stocks**: you own a piece of one specific company. Maximum potential return and maximum risk, because a single company can lose most of its value or fail entirely. Requires research to do well, and evidence consistently shows most individual investors underperform the market when picking stocks. Fine as a small portion of a portfolio for someone who enjoys it; poor as a beginner's core holding. **Mutual funds**: pooled money from many investors, managed as one portfolio holding dozens or hundreds of securities. Bought and sold directly with the fund house, priced once daily after markets close. Come in active (a manager picks holdings, higher fees) and index (tracks an index mechanically, low fees) varieties. In many countries, including India, mutual funds are the dominant retail vehicle and index mutual funds are excellent. **ETFs (exchange-traded funds)**: contain the same kind of basket as a mutual fund, but trade on a stock exchange like a share. You buy them through a broker at whatever price they're trading at, throughout the day. Typically low fees, often slightly lower than equivalent mutual funds, and generally more tax-efficient in some jurisdictions. **The practical differences that matter:** - **Buying**: mutual funds directly from the fund house, often with automatic monthly contributions; ETFs through a brokerage account like a stock. - **Pricing**: mutual funds at one daily NAV; ETFs continuously, with a bid-ask spread. - **Minimums**: mutual funds often allow small automatic monthly amounts, which suits regular salary investing. ETFs require buying whole units. - **Liquidity**: some ETFs, especially in smaller markets, trade thinly, which means wider spreads and worse execution. Check volume before buying. **For a beginner**: a low-cost broad index fund — as either a mutual fund or an ETF — is the sensible core. If you want automatic monthly contributions with minimal effort, an index mutual fund is usually simpler. If you already have a brokerage account and want the lowest fees, an ETF works well. The choice between them matters far less than choosing something broad, low-cost and held consistently.
