What is an ETF?
In one line: An ETF, or exchange-traded fund, is a fund that holds a basket of stocks, bonds or other assets and trades on an exchange like a single stock.
A simple example
Say an ETF tracks a stock Index of 500 large US companies. Buy one share of the ETF, and you own a tiny slice of all 500 at once.
ETFs charge a yearly fee called the expense ratio. It comes out of the fund quietly, not as a bill.
If the expense ratio is 0.10% and you hold $10,000 of the fund, the cost is about $10 a year. At 0.75%, it's about $75 a year. A math example, not a promise.
How it's different from a mutual fund
| ETF | Mutual fund | |
|---|---|---|
| When you can trade | Any time the market is open | Once a day, at the closing price |
| Price | Moves all day, like a stock | One price per day |
| Minimum | Often one share (or less, with fractional shares) | Often a set dollar minimum |
Why it matters
ETFs let you own a whole market, a sector or a theme in one trade. That spreads your money across many companies instead of one.
They also trade like stocks. You can see the chart, use Limit orders and set a Stop loss. So the same chart-reading skills work on them. See how the stock market works for the bigger picture.
If you add to an ETF over time, the average cost calculator shows your average price.
A common mistake
Assuming every ETF is a calm, spread-out fund. Some ETFs hold just one narrow theme. Others are "leveraged," built to move 2 or 3 times the daily move of an index.
Leveraged ETFs reset every day. Held for weeks, their result can drift far from 2× or 3× the index. Read what the fund holds before you buy it.
Questions
Is an ETF a good idea for beginners?
Many beginners start with broad ETFs because one share spreads money across many companies. They can still fall in value, so only use money you can afford to risk.
Do ETFs pay dividends?
Many do. If the stocks inside pay a Dividend, the fund usually passes it on to holders, often every quarter.
What is the difference between an ETF and a stock?
A stock is a share of one company. An ETF is a share of a fund that holds many things. Both trade on an exchange the same way.
