Exchange-Traded Fund (ETF)

An ETF is a fund that tracks an index, sector or asset class and trades on a stock exchange like a share.

Unlike unit trusts or OEICs, ETFs trade continuously throughout the day at market prices. Most major ETFs passively track an index (S&P 500, FTSE 100) with very low annual charges — often below 0.1% per year.

ETFs have largely replaced traditional index tracker funds for cost-conscious investors because they combine the diversification of a fund with the real-time tradability of a stock. The spread between bid and ask is the main additional cost.

Synthetic ETFs use derivatives to replicate index performance rather than holding the underlying shares — they carry counterparty risk that physical ETFs avoid.
