The cheapest and best index tracker funds and ETFs

Tracker and index funds offer simple low cost investing, where you ditch the costs and risks of trying to beat the market and follow it instead.

They are ideal for those who want to invest but don’t want the hassle of picking shares and want to avoid the often hefty costs using a traditional active fund manager involves. 

Index funds can keep costs ultra-low and while they won’t beat the market neither should they fall far behind it – the idea instead is that what has been called passive investing is a slow and steady method wins the race.

So if you are thinking why should you pay for a fund manager’s Porsche when you can get cheaper investing – and often better than average performance – by just following an index, we take a look at some of the cheapest index trackers and how to invest.

Even the world’s most famous investor Warren Buffett has advocated trackers – stating that the instructions on the estate he will leave for his wife is to put it 90% into index funds

Beware fees and tracking error

There is little point in deciding to invest through index funds and then opting for one that carries high fees, so whatever you do check the costs.

Another drawback to trackers is ‘tracking error’. This is where a tracker fails to accurately follow the index. It is normally only marginal but some funds can drift wider over longer time spans.

Those with the highest charges often have the worst tracking error: the effect of fees makes it impossible to keep up.

Another danger is that simple index funds hold companies proportionally to their size. Sometimes companies and sectors become huge, making up a big chunk of a stock market – leaving tracker investors highly exposed to individual stocks or sectors, as happened with banks in 2007. 

The best and cheapest tracker funds and ETFs

Below, we list some of the UK’s cheapest low-cost list the cheapest passive funds across investors’ most popular sectors including UK, UK Government bonds (Gilts), global, US, Europe-ex-UK and Japan, highlighting each one’s ongoing charges.

The ongoing charge is a better indication of the real cost than the annual management fee, taking all administration and dealing charges into account. 

But you also need to consider the overall cost of investing, which includes any dealing fees and platform charges.

Mutual index funds versus ETFs

The list features the cheapest traditional passive mutual funds as well as exchange traded funds (ETFs). Both are very low cost compared to active funds where the fund manager picks investments with the aim of trumping a market index.

The main difference between the two passive types is that ETFs are listed on stock exchanges and therefore trade throughout the day like a common stock; a mutual fund has its net asset value calculated once at the end of every day and can only be bought then.

This means ETFs have greater flexibility – or are more liquid in investment terms – but choosing these over a passive mutual fund won’t really make much of a difference if you do not buy and sell investments often.

Trackers may be cheaper to buy and sell compared with ETFs if you can find a platform that doesn’t charge for fund dealing, as ETFs usually incur a share dealing charge. 

It is also worth mentioning that some brokers have secured discount prices for certain funds, so it is worth having a look across the different investment platforms for the cheapest deals.

Tracker funds and efficient markets 

Tracking is far more effective in ‘efficient’ markets, such as larger companies in the UK and the US.

In countries such as these, financial systems ensure that everything investors need to know is in the public domain and well reported.

There are also big investing industries generating huge amounts of research on the biggest companies and employing a small army of people trying to profit from their shares.

Therefore, it is harder for a fund manager to seek out bargain stocks that have been overlooked and he or she will struggle to beat the index.

But in less efficient markets, such as emerging markets and Asia, or niche areas like smaller companies, stock-picking fund managers find it easier hunt out gems and therefore find it easier to beat trackers.You still need to spend some time picking a good manager though.
