There are a number of similarities between unit trust and exchange traded funds but also some key differences.
In both funds you own a share of the underlying investments in line with how much you have invested and how much you can invest in one transaction.
If a unit trust and an ETF track the same index, like the S&P500, the fund’s portfolios will be almost identical.
They are both liquid, transparent and low cost.
If the ETF is a collective investment scheme, the regulation of the underlying fund is the same.
The differences arise on how often the portfolios are priced. An ETF is priced throughout the day while a unit trust is priced once a day, but this should not worry you if you are a long-term investor.
Unit trusts report their holdings less frequently than ETFs, but the reason for this is that active fund managers prefer not to reveal their holdings that frequently. You will, however, always know what an index-tracking unit trust fund is investing in – the constituents of the index.
Providers of index tracking investments may offer an index fund as both an ETF and a unit trust fund, or one or the other, depending on what they think investors want. The choice of which index to track is where you should start and that may dictate which product you use.
If the index you want to track is available as either a unit trust or an ETF, you can compare the costs. You will need to take into account the costs of accessing the fund – either through the unit trust management company for a unit trust or a broker for an ETF, or investment platforms that offer access to one or the other.
When it comes to the performance of a unit trust and an ETF tracking the same index, you should a see similar performance, but it may differ because of:
The difference between the buying and selling price of an ETF on the stock market – known as the bid offer spread.
The size of the unit trust fund and inflows which can affect the custodian and trading costs.
