Deep dive: what is a fund?
A fund is one of the most common ways people invest – and one of the simplest once you understand what’s going on behind the scenes. At its core, a fund is just a large collection of investments bundled together. Instead of buying individual shares in lots of different companies yourself, a fund does it for you in one go.
What’s inside a fund?
A fund typically holds a mix of shares across many different companies – sometimes alongside bonds or other assets – spread across countries, industries, or themes. So instead of owning one company, you could own hundreds or even thousands at once.
Why funds exist
Funds are designed to solve a simple problem: most people don’t want to research, pick, and manage lots of individual investments themselves. A fund does the heavy lifting by spreading your money across many investments, managing them in one place, and making diversification easy from day one. In short, funds are a shortcut to diversification.
How a fund works
When you invest in a fund, your money is combined with other investors’ money and invested according to a strategy – either by a fund manager or an automated system. Your returns go up or down based on how those investments perform. You don’t own the individual companies directly – you own a slice of the whole fund.
Funds mean you don’t have to pick individual stocks or follow the markets daily. Just open a Stocks & Shares ISA, choose a fund, and let it do the work. It takes minutes to set up – start today.
Active vs passive funds
There are two main types. Passive funds aim to follow a market or index, like the FTSE 100 or global markets – they don’t try to beat the market, they simply track it. Active funds are managed by people trying to outperform the market by selecting specific investments. Most beginner and long-term investors tend to favour passive funds because they’re simple, diversified, and low-maintenance.
If investing in individual shares is like choosing books to read one by one, a fund is like subscribing to a library where everything is already included. You don’t have to choose every book – you just access the whole collection.
