ETFs — What an Exchange-Traded Fund Actually Is
한국어 English
An exchange-traded fund holds a basket of assets and trades on an exchange like a single stock. It combines the diversification of a fund with the intraday tradability of a share, which is why it became the default vehicle for index investing.
Verified facts
- An ETF holds a basket of underlying assets — most commonly the constituents of an index — and issues shares that trade on an exchange.
- Unlike a traditional mutual fund, which prices once per day, ETF shares can be bought and sold throughout the trading session at market prices.
- Most ETFs track an index rather than trying to beat it, which is why their management fees are typically lower than those of actively managed funds.
Reported, not confirmed
Statements from a single source, or where sources disagree- An ETF's market price can diverge from the net asset value of its holdings; the gap is usually small for liquid funds but can widen in stressed markets.
- Leveraged and inverse ETFs reset their exposure daily, so their returns over longer periods can differ substantially from a simple multiple of the index return.
Frequently asked
How is an ETF different from a mutual fund?
Both pool money into a basket of assets. The difference is how you buy them: a mutual fund transacts once a day at its closing net asset value, while an ETF trades on an exchange throughout the day at whatever price buyers and sellers agree on.
Why are ETF fees usually lower?
Most ETFs track an index mechanically rather than employing analysts to pick holdings. Less active management generally means a lower expense ratio, though fees vary and some specialised ETFs are not cheap.
Is the ETF price always equal to what it holds?
Not exactly. The market price can drift from the underlying net asset value. For heavily traded funds the gap is normally small, but it can widen when the underlying market is illiquid or volatile.
Are leveraged ETFs just a bigger version of the index?
No. They typically reset exposure daily, so holding one for weeks or months does not produce a simple multiple of the index's return over that period. This is a common misunderstanding.
