Exchange-traded funds (ETFs) offer several attractive features, including flexible intraday trading, efficient market access and potentially lower costs. While these benefits are clear to many investors, one of the most important ETF features, their liquidity, is less well understood. However, the ability to buy and sell ETFs quickly and easily, and at a reasonable price, is one of the biggest advantages of the ETF wrapper, for both active as well as index-tracking strategies.
Dispelling the myths
To understand the true liquidity of an ETF, it’s important to address the many misconceptions that surround ETF liquidity. Some of the most common ETF myths include:
- Myth #1: ETF liquidity is limited by underlying stocks' liquidity
Because ETFs and individual stocks both trade on a stock exchange, many investors believe that the factors that determine the liquidity of individual stocks must also determine the liquidity of ETFs.
Reality: ETFs operate in a 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 in the secondary market according to investor supply and demand. This unique creation and redemption mechanism, the primary market, which is enabled by experienced market makers and capital markets professionals, means that ETF liquidity can be 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.
Conclusion
An ETF’s liquidity can often be far greater than most investors assume. However, it’s important to work with your ETF provider, especially when placing large trades. Most providers have ETF Capital Markets desks whose role is to work with portfolio managers, authorised participants, market makers and stock exchanges to help assess true ETF liquidity and assist investors with efficient trade execution.
