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 the liquidity of the underlying stocks
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 have a unique creation and redemption mechanism that allows them to issue or redeem shares based on investor demand, unlike individual stocks with a fixed supply. This dual-layer liquidity comprising both primary and secondary markets which enables ETFs to have more dynamic liquidity than individual stocks. While the liquidity of an ETF is influenced by its underlying securities, it is not solely determined by asset size or trading volumes. As ETFs grow and attract diverse investors, secondary market turnover can often meet supply and demand. When imbalances do occur, the primary market facilitates efficient trading of the underlying stock basket, ensuring robust liquidity aligning the market price with its fair value.
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.
