Retail investors can only buy or sell ETF shares on a secondary market exchange. The “secondary market” liquidity seen on exchanges is important for ETF investors and traders. However, unlike stocks, ETFs possess another layer of liquidity considerations because of how they are created. The bid-ask spread is the difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask).
Questions sometimes arise about whether ETFs influence the prices of the stocks they hold. In short, the majority of ETF activity doesn’t affect the market prices of underlying stocks. ETFs are just one way for investors to express their views about the market.
If an ETF invests in securities that have limited supply or are difficult to trade, this may impact the market makers’ ability to create or redeem units of the ETF which may then affect the portfolio’s liquidity. However, most Canadian-listed ETFs predominantly invest in liquid securities that trade on major exchanges around the world. Liquidity is one of the most important features of exchange-traded funds (ETFs), though frequently misunderstood. An ETF’s liquidity refers to how easily shares can be bought and sold without impacting the ETF’s market price. An ETF’s liquidity is crucial because it impacts trading costs and helps determine how closely the ETF’s price tracks its underlying assets. ETF liquidity providers create and redeem shares through a process known as creation unit creation and redemption.
Management
ETF liquidity is influenced by several factors, including the trading volume of the ETF, the bid-ask spread, and the size of the creation and redemption units. While APs play a crucial role in ETF liquidity, it is important to note that not all ETFs have the same level of AP involvement. Some ETFs, particularly those with lower trading volumes or complex strategies, may have limited AP participation. In such cases, the liquidity and tradeability of these ETFs may be impacted, leading to wider bid-ask spreads and potentially higher trading costs for investors. The role of APs in ETF liquidity is critical to the functioning of the ETF market.
For instance, if an investor wants to sell a significant number of shares of an ETF with low trading volume and infrequent trades, they may struggle to find buyers and may have to accept a lower price to attract interest. On the other hand, an ETF with high trading volume and frequent trades would likely offer a smoother and more efficient trading experience. For example, ETFs that track illiquid assets may be more difficult to trade than ETFs that track liquid assets. Similarly, ETFs that use complex strategies or derivatives may also be less liquid because they may be more difficult to price and trade. In general, ETF providers should consider the liquidity of underlying assets when designing ETFs to ensure that they are able to provide sufficient liquidity to investors.

Can ETFs increase market fragility? effect of information linkages in ETF markets
When the ETF is less liquid, APs could find difficult trading at desired prices at the time of setting arbitrage positions or profit realization through unwinding. In this situation, APs could be reluctant to actively engage in arbitrage trading for low liquidity ETFs, or they could require additional returns even when available for arbitrage trading. As a result, APs can strategically wait for a tracking error (i.e., large arbitrage opportunity) to widen or increase the bid-ask spread to meet the additional required return on risk. This situation can cause investors to pay higher transaction costs and, thus, should lead to a case in which the elimination of the tracking error is delayed. The ETF variance could be larger than its net asst value variance owing to infrequent trading. 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.
Investors should carefully evaluate the liquidity of an ETF before investing and consider using limit orders or other trading strategies to ensure they are getting a fair price. One of the most important aspects of Exchange Traded Funds (ETFs) is their liquidity. Liquidity is the ease with which an asset can be bought or sold in the market without affecting its price. This is especially important for ETFs, as they are traded on stock exchanges like any other stock. ETFs can be bought and sold throughout the trading day, which makes them a popular choice for investors. However, the liquidity of ETFs depends on the underlying securities in the ETF, as well as the creation and redemption process.
In particular, any UCITS funds mentioned herein are not available to investors in the U.S. and this material cannot be construed as an offer of any UCITS fund to any investor in the U.S. Because ETFs have the same trading flexibility as stocks, short-term traders can use ETFs to quickly move in and out of a position. But ETFs are also a cost-efficient way to build a long-term, core portfolio. ETFs provide access to markets across the globe, ranging from specific countries to an asset class like global bonds – and even commodities like gold.
Liquidity can limit an investor’s ability to buy and sell without influencing the market price in an unfavorable way. In general, individual investors should stick to larger ETFs with high trading volumes and tight spreads to minimize their risk, while also making sure that the ETF’s holdings aren’t obscure or illiquid securities. Conversely, authorized participants can redeem ETF shares in large increments in exchange for the underlying securities, or cash, in the appropriate weightings and amounts.
Understanding ETF trading volume and liquidity
You set a price and execute your trade only if shares are available at that price or better. When you place a limit order, your priority is securing a certain price, not speed of execution. There can be no assurance that an active trading market for shares of an ETF will develop or be maintained.
- ETFs with high trading volume have more market participants, which means that there are more buyers and sellers in the market, making it easier to buy or sell shares.
- However, when you want to place an order for an ETF with a low ADV, it may be better to contact your ETF trading desk.
- However, the actual creation and redemption of ETFs takes place on the primary market between the ETF and authorized participants.
- Ireland is the main hub of ETFs in the euro area, with Irish ETFs managing €424 billion in assets as of September 2018, around two-thirds of the euro area total.
- APs and market makers operate in a highly competitive environment, and are economically incentivized to take part in making or trading ETF shares.
- Understanding these factors can help investors make informed decisions about when and how to trade ETFs.
With a multitude of use cases, it’s not surprising that ETFs are used by all types of investors. While all ETPs share certain characteristics, like the ability to trade shares on exchange, some have more complex risks and structural features. Examples of these products include defined outcome ETFs and those that seek to provide a leveraged or inverse return of their benchmark. The bid-ask spread is the difference between the highest price a buyer is willing to pay for an ETF share (the bid price) and the lowest price a seller is willing to accept for an ETF share (the ask price). A narrow bid-ask spread indicates that there is a high level of liquidity in the ETF, as there is a small difference between the buy and sell prices. A wide bid-ask spread indicates that there is a low level of liquidity in the ETF, as there is a large difference between the buy and sell prices.

The creation and redemption units are the minimum number of shares required to create or redeem an ETF. The creation and redemption units are typically large, and the process of creating or redeeming an ETF involves exchanging %KEYWORD_VAR% a basket of securities for ETF shares or vice versa. Authorized participants (APs) are responsible for creating and redeeming ETF shares. The size of the creation and redemption units affects the liquidity of the ETF.
The difference between the ETF variance and NAV variance can be interpreted as volatility arising from the trading effect in the secondary market, in addition to the inherent risk arising from the underlying asset portfolios. Considering the autocorrelation of the index return, we show that the non-trading probability is positively related to the increase in the ETF variance with respect to the NAV variance. In other words, the derived equation shows that the ETF return variance can be expressed as the sum of the NAV return variance and the additional term caused by infrequent https://www.xcritical.com/ trading of the ETF security in the secondary markets. Furthermore, our empirical analysis confirms that non-trading probability is positively related to the variance difference between ETF returns and NAV returns. These results suggest that investors investing in illiquid ETFs could bear additional unnecessary risk arising from the secondary market trading instead of investing directly in underlying portfolios or similar mutual funds. Unlike ETFs, which are traded on exchanges like stocks, mutual fund shares are bought and sold directly with the fund at the day’s closing NAV.
They provide liquidity by buying and selling ETF shares on the secondary market. When there is an increase in demand for an ETF, APs can create new shares to meet that demand. Conversely, when there is a decrease in demand, APs can redeem shares to reduce the supply. This helps to keep the ETF’s share price in line with its NAV and ensure that the ETF remains liquid. To understand why such differential effects occur across the two underlying asset classes, we rely on a theoretical framework that looks at links between assets that are formed via information channels. Information links are formed when investors use information from one asset to price the other (Cespa and Foucault 2014).
In order to ensure liquidity, exchanges like NYSE Arca have developed a network of market participants that play different roles in the ETF ecosystem. On the one hand, APs must constantly monitor the market and ensure that they are creating and redeeming shares at the correct price. They must also ensure that they have the necessary inventory of underlying securities to create new ETF shares. On the other hand, APs can profit from the spread between the ETF’s market price and the underlying securities’ net asset value (NAV). From the perspective of APs, the role can be both challenging and rewarding. APs must have access to a large inventory of securities in order to create and redeem ETF shares.
