Index fund

What is an index fund

An index fund is a type of investment fund that aims to track the performance of a specific stock index or another market benchmark. The goal is to match the index's performance through passive management, without actively selecting individual stocks.

How an index fund works

An index fund buys and holds all, or a representative sample of, the stocks or other assets included in the given index. For example, a fund tracking the S&P 500 invests in the companies that make up the index, in the same proportion as the index itself.

Advantages of an index fund

• Low fees – thanks to passive management.
• Broad diversification – investing in many companies across sectors.
• Transparency – the fund's composition is easy to verify.
• Historically stable returns – in line with overall market performance.

Disadvantages of an index fund

• Inability to beat the market – returns track the index, so excess return (alpha) is not expected.
• Market dependency – when the market falls, the fund's value falls too.
• Less flexibility compared to active management.

Index fund vs. ETF

While they follow a similar principle, ETFs trade on the exchange like stocks, whereas index funds are typically bought and sold once a day at the price set at market close.
