How much does it cost to invest in the index?

Copy link to section

From $0 to $5, depending on how you invest. For each option, you must consider the cost of buying the actual asset, whether that’s an ETF, index fund, CFD*, or share, plus the fees associated with it.

*Note that CFDs are not available to US investors.

ETFs and CFDs are generally the cheapest option overall, as they have low fees and a low minimum investment. Index funds and mutual funds have low fees but may have a high minimum investment. Buying individual stocks is the most expensive option in absolute terms, because the share price of a single large company is often more than $100.

All options are likely to include a trading fee, which you pay each time you make a transaction. Some trading platforms offer zero-fee trading, with others it may be a few dollars. 

Then ETFs and index funds each have their own expense ratio. Expense ratios refer to an annual management fee, charged as a percentage of your total investment. Expense ratios are usually no more than 0.05%, so if you invest $1,000, you would pay $5 per year in management fees.

The different ways to invest in the TVAVF

Copy link to section

As we mentioned above, there are numerous ways to put your money into the . ETFs and individual stocks are the simplest options for beginners, but there are alternatives. Here’s a brief overview of each option and who it’s best suited for.

ETFs

Copy link to section

An ETF (exchange-traded fund) is an investment fund traded on a stock exchange, much like a stock. Exchange traded funds can hold different assets, such as individual stocks, bonds, or commodities, or serve as a proxy for a stock market index.

An ETF is one way of investing in the . It’s simply an investment fund that mirrors the performance of the . When you buy shares in the fund, the value of your investment will rise or fall with the itself. 

ETFs are ideal for new investors because they have a very low minimum investment. You can start with a few pounds and get exposure to some of the world’s largest companies. They’re also practical if you plan on trading the index, because you can buy or sell shares in the fund throughout the day.

index funds

An index or mutual fund is an investment fund that aims to track the performance of a stock market index, such as the . It’s very similar to an ETF, in that there are low management fees and you can buy shares through your online broker.

However, there are a couple of differences. index funds are only priced at the end of each trading day, so you can buy or sell shares in the fund once per day. There may also be a higher barrier to entry, through a much larger minimum investment when you invest in index funds.

That means an mutual fund is better suited for long term investors with a higher initial budget, where the infrequent trading and barriers to entry are far less of an issue.

CFDs (non-US users only)

Copy link to section

CFDs (contracts for difference) are a way to speculate on price changes with more flexibility than if you use an ETF or index fund. A CFD is a ‘derivative’, which means it gets its value from the underlying asset – in this case the – but it’s separate from it.

As a result, CFDs can be leveraged, where you borrow money to multiply the size of the trade, or they can be used to go ‘short’, where you place a trade on the index to fall in value. You can also buy and sell them outside of regular trading hours.

All of this means CFDs offer the potential to outperform a fund that passively tracks the ’s performance. Of course, you can also underperform it as well. Tools like leverage and shorting introduce a lot more risk, and are best left to experienced traders.

futures

Futures contracts are agreements to buy or sell the TVAVF at an agreed price on a set date in the future. futures are a means to predict how you think the index is going to perform over a set time frame, such as the next three or six months.

Most futures contracts involve leverage, so you only put up a small part of the total trade value (the margin) when you buy one. That makes futures more risky, and they require a bit more financial expertise to understand as well.

Some traders use futures as a hedge against the performance of stocks they own. For instance, if you own stocks that are part of the then you might want to short the so that you still make some money if the price falls.

stocks

Copy link to section

Another way to invest in the is to buy shares in the individual stocks that the index tracks. It isn’t practical to buy every share in the index, but you can invest directly into a few of the most heavily weighted stocks in the in order to get broad exposure to its performance.

The most heavily weighted stocks in the tend to be the largest companies by market capitalisation. If you invest directly in those largest stocks, you gain exposure to the index without taking on the risk of all the underlying companies.

One reason to do this is that these larger companies with the highest market cap dominate the index anyway, so that it can give you the impression of a diversified portfolio while actually being reliant on the performance of those particular stocks.

The flip side of investing directly like this is that you lose the diversification and stability that comes with buying into an entire index. It requires much more hands-on management to do your own stock picking, so it’s best suited to more experienced investors.

Should I invest in the index? 

Copy link to section

Yes, investing is a great choice if you’re looking for a safer investment with more price stability compared to picking individual stocks. It’s also ideal if you don’t have the time to actively manage a portfolio of stocks, because you can simply invest in a bunch at the same time and then leave it alone.

The flip side is that you have less control over which companies you invest in. An index committee decides how the index works, and you can’t pick and choose the underlying companies you like the most. The is better suited to hands-off investors, compared to those who have the skills, experience, and desire to pick their own stocks.

An index provides instant stock market diversification, where you spread your risk across a large number of underlying companies, rather than one or two. Here are some more reasons why you might want to invest in the S&P/ASX 200 index:

Historically, the Australian stock market has experienced periods of growth.

What are the disadvantages of investing in the S&P/ASX 200 index?

Copy link to section
