Types of investment funds

There are many different types of investment funds, but in this guide, we’ll focus on the ones open to retail investors like you.

What Is a Mutual Fund

The concept of a mutual fund is simple.

Picture a big basket, but instead of fruits, this basket holds stocks, bonds, or other investable assets. The basket is managed by professional investors who decide what to buy and sell, and when you buy shares in a mutual fund, you’re essentially buying a slice of everything in that basket.

“Mutual fund” is also a broad term. 

There are many different types of mutual funds, each catering to different types of investors and their various goals, interests, and risk appetites. For instance, some funds are focused on growth, so they consist of assets such as stocks in companies that have high growth potential.

On the other hand, some funds are focused on steady, low risk returns, so they might consist of fixed income assets like bonds. There are also thematic funds that consist of assets that give you exposure to a particular industry or theme, such as AI, or ESG, and the list goes on.

What is an Index Fund

One of the most popular types of mutual funds are index funds.

Index funds track indexes, so first let’s clarify what an index is using the S&P500 as an example. An index tracks the performance of stock prices of a specific group of companies. The S&P500 for example, tracks the performance of the 500 largest publicly-traded companies on the US stock exchanges.

As the value of the stocks in the S&P500 goes up, the index rises. On the contrary, if the average stock price drops, the index falls.

Index funds replicate the indexes they track, so an S&P500 index fund will include stocks of all the companies in the S&P500 weighted by their respective market capitalisations. So, the larger the company, the larger their weight in the index. For the S&P500, the top 10 stocks which includes the likes of Microsoft, Apple, Amazon, Meta and Google actually account for more than 30% of the overall index. 

Like with mutual funds, when you buy shares in an index fund, you own a slice of all the stocks in that fund and hence, investing in the S&P 500 will give you a large exposure to the companies I just mentioned. 

What is an Exchange-traded Fund (ETF)

Similar to index funds are exchange-traded funds, also commonly known as ETFs. Like mutual funds, ETFs can be thought of as a basket of companies. When you buy shares in an ETF, you own a slice of all the companies in that basket. There are also many different types of ETFs, catering to different investor goals, interests, or risk appetites. 

So, what's the difference between an ETF and a mutual fund? The main difference is that shares in ETFs are traded on stock exchanges while shares or units in mutual funds must be bought directly from the fund.

There are also a number of other differences, such as the way ETFs and mutual funds are managed and their different cost structures, but we’ll talk about these in a later guide. For now, just remember that all funds follow the basic concept of a basket of investable assets - each put together for a different purpose, and these funds can either be invested via fund or portfolio managers, or traded directly on an exchange, like the NASDAQ or New York stock exchange.
