ETFs and single shares: what's the difference?
A share is a slice of one company; an ETF is a basket of many, traded like a single share. How they differ on risk, cost and effort.

A share: one company
A share (or stock) is a small piece of ownership in one company. If the company grows and earns more, the share may rise in value and may pay part of its profit to you as a dividend. If the company struggles, the share can fall, sometimes to zero.
An ETF: a basket in one wrapper
An ETF (exchange-traded fund) is a fund that holds many investments at once (often all the shares in an index) and is itself traded on a stock exchange like a single share. Buying one unit of an ETF that follows the Euro Stoxx 50 gives you a small slice of all 50 companies.
Side by side
| Single share | ETF | |
|---|---|---|
| What you own | Part of one company | A slice of a basket of many |
| If one company fails | You can lose everything you put in | It is a small part of the basket |
| Ongoing cost | None from the share itself | A yearly fee (the TER), taken from the fund |
| Effort | You need to follow the company | The fund follows its rules for you |
| Still risky? | Yes | Yes: if the whole market falls, the ETF falls too |
Words you’ll see
- TER (total expense ratio): the yearly fee as a percentage of what you hold.
- Accumulating vs distributing: whether the fund reinvests dividends or pays them out.
- UCITS: the EU rulebook most ETFs sold to the public in Europe follow.
- KID: the short Key Information Document every EU fund must publish, with its costs and a risk score from 1 to 7. Read it before buying anything.
Nothing here says which is right for you: that depends on your situation, and a regulated adviser is the person to ask.
Questions people ask
Is an ETF safer than a single share?
An ETF that holds many companies spreads the risk of any one of them failing, but it still rises and falls with the market it follows. You can lose money with both.
What is a UCITS ETF?
UCITS is an EU rulebook for investment funds sold to the public. Most ETFs sold to retail investors in the EU are UCITS funds, which sets rules on how they invest, diversify and report.
