IU.eu: How many ways of trading an ETF in the secondary market are there?

Kssis: I would say there are five main ones that investors should be aware of.

The first way is the standard method of trading on-exchange. Here, you pay the quoted screen prices, including the bid-offer spread. For smaller, retail investors, this is typically the only method you are likely to use.

The second way is more used by institutions, and is a so-called "risk trade." The investor goes to a market counterparty and says, for example, “What’s your bid-offer price in €5 million of the MSCI World ETF?” The market maker gives bid and offer prices, the investor decides whether or not to trade, and if a transaction takes place the investor knows that he’s fully transferred the risk or exposure to the market maker, and there can be no price slippage. The institutional investor will also often choose this method as the bid-offer spread is likely to be tighter than if he trades at quoted screen prices. The reason for this is that, since market makers are obliged to maintain live two-way quotes on several exchanges in the same ETF, they will often quote a slightly wider bid-offer spread to protect themselves against the risk of being “hit” on several dealing systems simultaneously. If you call the market maker up, you are quite likely to get a more competitive price.

The third option is to work an order, particularly if you are dealing in large size. You might split a large transaction into smaller lots and try to execute it over a period of time, particularly if you are expecting a market movement, say around the time of some economic release, and you want to stagger your purchase or sale.

The fourth option, which has become less popular than it used to be, is to trade at the closing stock exchange auction. A lot of passive fund managers have their performance benchmarked to the closing market price, and so they have an incentive to trade in this way. Although there is typically extra liquidity in the underlying stocks at the closing auction, there may not be the same liquidity in the ETFs, so you need to coordinate this with a market maker if you are planning to do it, since otherwise you may find your order doesn’t get fully executed.

The fifth and most popular method for institutional investors is to trade at the net asset value, which removes the bid-offer spread, although you have to pay the ETF provider’s creation or redemption costs. This is not the same as trading at the closing auction, since at the auction an ETF might well end up at a premium or discount to NAV.

For institutions there is also a trade that can take place throughout the day, called exchange for physical, where you can exchange a basket of stocks for an ETF. This is a so-called “basis trade”, where a basis or spread between the ETF and the basket of stocks will be priced by the market maker, and usually the execution will be agreed by both parties to take place at a given time of day.

IU.eu: How does the market maker then create a price in the ETFs he is quoting on a continuous basis?

Kssis: The market maker will start by calculating the net asset value of the ETF, that is, the value of the underlying basket of stocks. If the underlying market is closed we look at the futures market, or we can use our own correlation models, to set an ETF price. Our quote will also reflect any creation or redemption fees that the ETF issuer charges. We also typically quote without specifying where in Europe the ETF will actually be delivered—that is, in which depositary system—and the investor can choose that himself. If you trade using screen prices for a given ETF you often find that the most attractive quotes may be split across several countries and you may have to deliver or receive executed ETF orders within different depositary systems.

IU.eu: How do you hedge yourselves if you’ve completed a transaction in an ETF and end up with a long or short position that you need to cover?

Kssis: We use sector products such as swaps, futures on country indices, and individual stocks, to do this. Each market maker will have its own team of quantitative analysts, which calculates the fair value of the ETFs it offers two-way prices in, and also the best ways of hedging. Different market makers won’t necessarily agree on the same fair value for a given ETF, by the way.

IU.eu: What, then, are the most important things that a European ETF investor should know about secondary market trading?

Kssis: The investor should be aware that quoted stock exchange trading volumes do not necessarily reflect true trading activity or secondary market liquidity, he should check how many market makers are involved with a particular fund to ensure that secondary market quotes are competitive, and he should be aware of the many different ways of placing a secondary market trade, in order to get the right kind of execution for his requirements.
