There are a lot of reasons to like listed managed investment structures such as ETFs, ETMFs, active ETFs and LICs. Listed investments benefit from expert management and diversification, while also being transparent, accessible and – on the whole – cheap.  

But there are drawbacks. Listed managed structures can be plagued by misleading indicative net asset values (iNAVs), spread instability, and – thanks to that ease of access – have the potential to encourage losses through short term trading.

LICs have also been known to trade at a meaningful premium or discounts to their net asset value, making it difficult to work out if you’re getting a good deal for what you are paying.

That's why Morningstar analysts can have a lower rating for listed structures where there is both an investment trust and a listed vehicle for the same strategy.  

While as investors we often focus on the management fees of any investment, Morningstar senior manager research analyst Matt Wilkinson says when it comes to listed structures the spread between the buying and selling price is also important. 

What are buy/sell spreads? 

A spread is the gap between bid and ask prices of a stock or other security. The bid is the price that someone is willing to pay for a security at a specific point in time, whereas the ask is the price at which someone is willing to sell. The difference between the two prices is called the bid-ask spread. 

The market depth lists all the buy and sell orders in the market for a particular listed security. 

Why are spreads an issue for listed investment structures? 

Speaking at the Morningstar Individual Investor Conference in Sydney last month, Wilkinson used a series of charts to demonstrate why wide spreads can be an issue for investor. 

This is a chart of an ETF, where the daily closing price is plotted.

It shows an enormous daily range on some days. The people selling at the bottom or buying at the top of these peaks and troughs are getting terrible prices. 

So why is this happening? 

Wilkinson says the answer lies in the structure of listed managed investment products and how they trade on the market.  

If you're trading highly liquid securities, the bid-ask spread will tend to be pretty inconsequential, meaning that buyers and sellers generally agree about what the right price for a security should be.  

But bid-ask spreads can be more onerous when you're dealing in more thinly traded securities, such as ETFs with light trading volume.  

Wilkinson says this is because the bid-ask spread compensates the market maker in the security – the market middleman from whom you buy, or to whom you sell, the shares in the company. 

"The aggregate of all market participants will widen or narrow the spread depending on supply and demand ultimately," he said 

"This is our issue with some listed products which means few achieve a Morningstar Gold rating, particularly those where the market makers are the main market participant – and that's particularly in newer products. 

"Market makers have greater knowledge than other participants." 

What types of products are most vulnerable? 

While Wilkinson says the impact will be felt primarily by smaller and newer listed product, even large and very liquid listed products can be affected.  

For example, on 9 November 2016, the day of the US Presidential election, the ASX experience an enormously volatile trading day. At the start of the day, the spread on the iShares Core S&P/ASX200 ETF was minimal, but when the results came through, the spread blew right out.

So how can you reduce the drag on your returns?  

At the risk of stating the obvious, reducing your number of transactions is a good starting point, particularly if you're dealing in any type of illiquid security.  

Another way to exert more control is to use a limit order rather than a market order. By doing so, you're saying that you're not going to accept any old price when buying and selling; you only want to transact if you can get a specific price or better. 

Wilkinson has another idea. He says a study of spreads over the course of a trading days shows there is a clear concentration of price spiking due to wider spread in the morning.  

There are two main reasons why: 

It’s the time of the day when market makers are initiating their systems. The less liquid products particularly are more prone;  

And when most overseas markets are closed making pricing of global ETPs much more difficult. And as Asian markets open, this brings an increase level of uncertainty and volatility to local prices for a time. 

But by the afternoon, it all settles down.  

This is typical of any trading day:

His message? Be more careful when trading at the beginning of the day and during times of volatility. Lastly, Wilkson encourages investors to check the market depth and the spread before trading ETFs, ETMFs and LICs. You can do this via your online broker.
