ANSWERS TO TWELVE POPULAR QUESTIONS ABOUT ETFs

Typically, no. In fact, ETFs globally have acted as “shock absorbers” during many volatile trading sessions as buyers and sellers transacted on the exchange, at real-time prices, without having to trade the underlying stocks and bonds.¹

What’s more, since ETF shares are traded directly by buyers and sellers on-exchange, an ETF can circumvent “forced selling,” something a mutual fund may need to do when investors want to sell their shares. This means that most ETF trading occurs without transactions taking place in the underlying securities.

Given the size of some of the largest ETFs, one might think that buying and selling within those funds significantly moves market prices. However, it is asset allocation decisions made by asset owners, such as superannuation funds and individuals, that drive flows into different asset classes, sectors, and geographies.

These allocation decisions are generally guided by factors such as macroeconomic developments (like global interest rate policy), risk preferences, and investment horizon.

ETFs are just one way for investors to express their views about the market. If ETFs didn’t exist, investors could use other tools, like single stocks, mutual funds, and derivatives.

ETFs are unique; they provide exposure to a diversified collection of assets, like a mutual fund, but trade on exchange, like a stock. This structure makes the liquidity of ETFs unique, too.

Liquidity refers to the ease of buying or selling a security. ETFs have two layers of liquidity: primary market liquidity, which is provided by the underlying securities or instruments of the ETF, and secondary market liquidity, which is provided by the ability to trade ETFs on exchange.

This means that ETFs are net contributors to market liquidity. At a minimum, an ETF will be as liquid as its underlying securities or instruments; however, many ETFs can provide even greater market liquidity than their underlying instruments.

ETFs have grown quickly in both size and scope over the past decade. Despite this, assets under management in ETFs are only a fraction of the global financial market in both equities and fixed income.

Even in the most mature market the US, ETFs only represent 12.6%² of equity assets. These numbers are even smaller in other regions at 8.0%³ in Europe, and 4.2%⁴ in Asia-Pacific. Market share is even smaller in fixed income, where ETFs account for 2.7%⁵ of fixed income assets in the U.S., 1.8%⁶ in Europe, and 0.4%⁷ in Asia-Pacific.

In Australia ETFs account for just under 6% of equity assets as of September 2023⁸ and just 0.6% of fixed income assets as of June 2023.⁹

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 those that seek to provide a leveraged or inverse return of their benchmark.

As the number of ETPs has increased, so too has the number of more structurally complex products, including ETPs with different risk profiles and more narrowly tailored investment objectives.

BlackRock is supportive of efforts to increase awareness and transparency around the risks and structural features of complex products, and we have long advocated for a clear categorisation of ETPs that may have differing risks and complexities.

Index providers periodically make changes to, or rebalance, their indexes. This includes adding, deleting, and making changes to the weights of securities in the indexes they manage. Because index funds seek to track the performance of an index, they also adjust their holdings when index rebalances happen.

There are a multitude of decisions that must be made leading up to and during index rebalances. At BlackRock, professional index fund managers take a disciplined approach to managing rebalances as they seek to deliver fund performance outcomes that align with index performance.

At iShares by BlackRock, we measure ETF investment performance not only by how well our ETFs track their indexes, but also by how we deliver the performance our investors expect in a cost- and tax-efficient way. This includes paying close attention to the market quality of our products, or their ability to offer liquidity and efficient access to markets in varying market conditions.

The first component of our investment performance framework is precision. One of the most important criteria in measuring the performance of index products is how well they deliver or track index returns — and their ability to do so consistently over time. This also includes assessing how efficiently the funds manage index rebalances to optimise outcomes for investors.

For ETFs, iShares uses a second component to measure investment performance: market quality or their ability to offer liquidity, price discovery, and efficient access to markets in varying market conditions. To measure the market quality of an ETF, it is important to consider metrics that span both primary and secondary market activity. Importantly, these metrics must be studied holistically; when reviewed in isolation, one metric may not tell the whole story.

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.

From the period of December 2020 through December 2022, approximately only 5.6% of equities trading volume in the largest market the U.S. has been attributable to ETF activity. In other regions these numbers are again lower. In Europe, just 1.9% of trading in individual European stocks has been attributable to ETF flows. In Asia-Pacific, this figure is even lower at 1.4%¹⁰.

An authorised participant (AP) is a financial institution that manages the creation and redemption of ETF shares in the primary market. Each AP has an agreement with an ETF sponsor that gives it the right (but not the obligation) to create and redeem ETF shares. APs may act on their own, or on behalf of market participants. Market makers are broker-dealers that regularly provide two-sided (buy and sell) quotes to clients. In some instances, an ETF’s market makers may also be APs. APs and market makers operate in a highly competitive environment and are economically incentivised to take part in making or trading ETF shares.

Historically, if an AP has withdrawn from the ETF market, other APs have stepped in to facilitate the creation and redemption of ETF shares, particularly if there was a significant premium or discount to its net asset value (NAV), or difference between the price of the ETF and its underlying holdings. This is because APs generally seek to take advantage of economic arbitrage opportunities arising from that difference (for example, if an ETF is trading at a price above its NAV, an AP could buy the underlying securities and exchange them with the ETF issuer for newly created ETF shares, which may then be sold in the market for a profit).

That same incentive holds true for market makers as well. A market maker regularly provides two-sided (buy and sell) quotes to clients on the exchange. Market makers are key liquidity providers in the ETF ecosystem that ensure continuous and efficient ETF trading in the secondary market.

The role of a market maker is distinct from the role of an AP, though both are necessary for robust ETF trading activity. A market maker does not need to be an AP, nor does an AP need to be a market maker. Still, some firms play both roles in certain ETFs. Ultimately it is this “arbitrage mechanism” that helps keep the ETF’s market price close to the value of its underlying holdings each day.

In Australia, each listed ETF is required to have a designated market maker, this market maker has set obligations to provide a minimum quantity at a spread up to a defined maximum schedule for at least 80% of the time during market hours. These obligations are set out in a contract with the ETF issuers.

iShares have multiple market makers on all ETFs including but not limited to the designated market maker.

Examples of market makers include JP Morgan, BNP Paribas, Susquehanna, Jane Street and Nine Mile Financial.

Price discovery helps investors identify the proper market price of securities or other instruments based on factors like supply and demand. The on-exchange trading of ETFs plays an important role in price discovery across markets, sectors and individual stocks. ETF flows provide crucial information. As greater numbers of investors use ETFs to express their views, flows from one asset to another can serve as indicators of investor sentiment about potential risk and return. Note that ETFs don’t set prices or drive volatility. They hold up a mirror to what investors are thinking.

ETFs can be used for a variety of reasons, such as a financial instrument for a tactical decision or as a tool for efficient market access as a long term buy and hold in an investor’s portfolio. With a multitude of use cases, it’s not surprising that ETFs are used by all types of investors.

Unlike equity markets, the bond market is highly fragmented and opaque. There are hundreds of thousands of unique fixed income securities. Furthermore, unlike equity securities, most bonds don’t trade on a given day. These attributes of the bond market can make it challenging for a bond fund to attempt full replication of bond indexes which can include thousands of securities.

Accordingly, ETFs tracking such indexes are generally “sampled” (i.e., they hold a subset of securities that meet the risk profile and characteristics of the parent index to seek the index exposure). iShares Portfolio Managers evaluate which bonds to select for fixed income ETF portfolios through a systematic process that includes evaluating multiple risk and liquidity factors while seeking to match the risk and characteristics of the benchmark index.

The creation and redemption baskets — the securities delivered by an Authorised Participant to the ETF for a creation of ETF shares, and vice versa for a redemption of ETF shares — generally aim to be representative of the broader index to maintain the ETF’s investment objective of tracking the index. Sampled baskets lead to a reduced security count relative to the reference index, but the presence of fewer securities does not automatically translate into concentration of risk.
