ETF Liquidity: Trading during volatile markets

Exchange-traded funds (ETFs) offer many benefits to investors, including flexible intraday trading, efficient market access and potentially lower costs. But one of the most important ETF features—their liquidity—is also one of the most widely misunderstood.

Dispelling the myths surrounding liquidity and ETFs

Liquidity refers to the ability to buy or sell a security quickly, easily and at a reasonable transaction cost. ETFs and individual stocks both trade on a stock exchange, leading many investors to believe that the factors that determine the liquidity of the two securities must also be similar. They’re not. ETF liquidity can often be far greater than most investors assume.

ETFs actually operate in a fundamentally different ecosystem to other instruments that trade on stock exchanges, such as individual stocks or closed-end funds. Whereas these securities have a fixed supply of shares in circulation, ETFs are open-ended investment vehicles with the ability to issue or withdraw shares on the secondary market according to investor supply and demand.

This unique creation and redemption mechanism means that ETF liquidity is much deeper and much more dynamic than stock liquidity. It also explains why an ETF‘s liquidity is predominantly determined by the liquidity of its underlying individual securities, rather than by the size of its assets or by trading volumes.

Guidelines for determining liquidity and trading ETFs

Although ETFs have many characteristics that are similar to stocks, liquidity is not one of them. Therefore, it‘s important to look beyond trading volumes and on-screen indicators when assessing ETF liquidity. Here are some of the dos and don’ts of ETF liquidity.

1. Don’t use trading volumes or fund size as a guide.

Perhaps the most common ETF misconception is that funds with low daily trading volumes or with small amounts of assets under management will be difficult or expensive to trade. This is not the case. Thanks to the ETF creation and redemption mechanism, small- or low-trading-volume ETFs are usually able to absorb large buy or sell orders while continuing to trade at prices that are typically close to the net asset value of their underlying securities.

2. Look at total ETF liquidity in the secondary and primary markets.

Because market makers—who maintain continuous two-way ETF orders and are a key input to exchange order books—typically display only a small fraction of the volume they are willing to trade, investors may find that secondary market liquidity is actually much higher than on-screen indicators suggest. Investors with large ETF trades can also tap into primary market liquidity by working with an authorized participant to create or redeem ETF shares directly with the fund company.

3. Use limit orders as the default order type when trading ETFs.

A limit order—an order to buy or sell a set number of shares at a specified price or better—gives investors some control over the price at which the ETF trade is executed. By contrast, a market order—an order to buy or sell immediately at the best available current price—may end up being executed at a price that is far higher (or lower) than expected as the order sweeps through standing orders on the order book.

4. Consider the time of day when placing ETF trades.

As a general rule, trading at times when it is difficult for market makers and other institutional investors to hedge underlying securities in an ETF will likely result in wider spreads and less efficient trades. This is typically the case just after U.S. equity markets open and just before they close. U.S. ETFs with underlying securities in international markets are subject to additional liquidity considerations, notably the fact that the stock exchanges on which the underlying securities trade may be closed while U.S. exchanges are still trading. In that interval, the underlying securities are less liquid, which can result in wider bid-ask spreads.

5. Work with your ETF provider, especially when placing large trades.

Don’t go it alone. Most providers have capital markets desks whose role is to work with portfolio managers, APs, market makers and stock exchanges to help assess true ETF liquidity and assist investors with efficient trade execution.

Investing involves risk including possible loss of principal. International investing has a greater degree of risk and increased volatility due to political and economic instability of some overseas markets. Changes in currency exchange rates in different accounting and taxation policies outside the U.S. can affect returns. Diversification does not guarantee investment returns and does not eliminate the risk of loss. Diversification among investment options and asset classes may help to reduce overall volatility. Investing in alternative assets involves higher risks than traditional investments and is suitable only for sophisticated investors. Alternative investments involve greater risks than traditional investments and should not be deemed a complete investment program. They are not tax efficient and an investor should consult with his/her tax advisor prior to investing. Alternative investments have higher fees than traditional investments and they may also be highly leveraged and engage in speculative investment techniques, which can magnify the potential for investment loss or gain. The value of the investment may fall as well as rise and investors may get back less than they invested.
