Exchange traded funds (ETFs) are known for their tradability. With just over $10.6 trillion in secondary market notional volume in the first quarter of 2024 — more than the next five most actively traded ETFs combined — the robust liquidity of the SPDR® S&P 500 ETF (SPY) sets the benchmark of implementation flexibility for a wide array of trading strategies.¹

Yet with 88.3% of all US-listed ETFs trading less than $25M per day, on average during Q1 of 2024,² we’re mindful that trading the vast majority of less liquid ETFs efficiently can take a little more attention. We’re here to help.

As a liquidity leader, SPDR ETFs accounted for 33.6% of all notional trading volume of US-listed ETFs in Q1 of 2024.³ The SPDR Sales Execution and Institutional Strategy Team is a dedicated group of capital markets professionals focused on providing resources to help assess ETF liquidity and evaluate different execution strategies for the entire range of SPDR ETFs.

Determining Execution Objectives — One Size Does Not Fit All

As the number of ETFs in the marketplace has grown, investors have increasingly dedicated resources to evaluating ETF liquidity as a key component of their total cost of ownership (TCO). For all SPDR ETFs, our Sales Execution and Institutional Strategy Team can help you evaluate different execution strategies with the goal of optimizing investment objectives and TCO. The SPDR team can help assess:

Execution priorities

What is the timeframe for execution?
Is the creation/redemption window open?
Based on trade objectives, which is the correct type of order to use?

Trade considerations

Is the trade of a social size, or is it outsized in comparison with the ETF’s historical average volumes?
What is the trade size relative to the underlying market?
Are the underlying constituents open to trade due to local market hours or holidays?

Market environment

Is the market trading in an orderly fashion (i.e., volatility halts)?
Is the ADV drastically higher/lower than normal?
Is the ETF’s bid/ask wider than usual?
Is there currently an outsized premium/discount?

Match Execution Strategies with Portfolio Objectives

ETF secondary trading volume is often the first measure of ETF liquidity. However, investors with larger order sizes can source liquidity not displayed on the screen from liquidity providers. ETFs are at least as liquid as their underlying constituents at any given point in time. With ETFs representing a multitude of asset classes, geographies, sectors, and styles, the SPDR team is available to navigate different market environments and volatility regimes to properly evaluate execution strategies and meet your objectives.

Execution Strategy	Description	High Urgency	Market Impact Sensitivity	Time Risk	Anonymity
Risk Trade	Client received price for the entire trade at once, and the liquidity provider takes on the risk of managing the result position. Liquidity providers can be put in competition for the trade, allowing for a clear measure of best execution. Client generally benchmarks vs. the quoted NBBO.	Yes
NAV Trade	Trade executed by buying or selling the underlying basket of securities and subsequently creating/redeeming ETF shares. The client typically receives a price reflective of executions for the underlying basket of securities plus or minus creation/redemption costs. Client generally benchmarks vs. end of day NAV.		Yes	Yes
Worked Order	Electronic order types using automated preprogrammed trading instructions. Orders can be measured relative to execution benchmarks based on volume, time or other metrics. Can be applied to both trading in the secondary market or trading the basket.		Yes	Yes	Yes

Trading the SPDR® MSCI USA StrategicFactors℠ ETF (QUS)

The SPDR® MSCI USA StrategicFactors℠ ETF (QUS) seeks to track the MSCI USA Factor Mix A-Series Capped Index, a Smart Beta index that blends low volatility, quality, and value exposures together in a single strategy and bridges the gap between active and passive management. As a result, QUS provides an opportunity for investors to rethink exposures and potentially maximize risk-adjusted returns more efficiently. The fund averaged roughly $3.8M in secondary notional value over the last 30 days, as of March 28, 2024.⁴

Investors seeking to trade orders of $15M–30M would represent a significant portion of the secondary volume but may consider trading the ETF on risk with a liquidity provider.

Let’s walk through execution considerations:

Execution Priority Trade Strategies: Can be developed to best align with the client’s execution priorities including cost, immediacy of trade, and anonymity.
Trade Considerations: The order size represents a large percentage of QUS’s secondary trading volume, but a small percentage of the underlying basket volumes. The 30-day average daily aggregate volume of QUS’s underlying securities was more than $360.5B.⁵
Market Environment: Is there news or are there macro-related headlines that may impact market volatility or cause uncertainty for liquidity providers? The chart below shows the impact volatility had on QUS’s bid/ask spread.

Secondary Market Block Trades:

We can see in the chart below that risk trades in the $10M–40M range have occurred in QUS as investors have sourced liquidity from providers. Each example should be evaluated independently, as time of day and market environment can impact relative pricing. However, these block trades should serve as helpful historical examples of risk trades executed during different market environments.

On January 7, 2022, a client bought approximately $31.4M of QUS. At the time that the trade took place, the market was 128.29/128.33. For reference, the VIX Index was priced 18.8 at the time of the trade.

The client received an execution price equal to the national best bid/offer (NBBO) on the trade, implying 1.6bps of impact.
This trade was 3.7 times the fund’s Q1 2022 average value traded.

Investing involves risk including the risk of loss of principal.

Diversification does not ensure a profit or guarantee against loss.

In general ETFs can be expected to move up or down in value with the value of the applicable index. Although ETF shares may be bought and sold on the exchange through any brokerage account, ETF shares are not individually redeemable from the Fund. Investors may acquire ETFs and tender them for redemption through the Fund in Creation Unit Aggregations only. Please see the prospectus for more details.

Equity securities may fluctuate in value and can decline significantly in response to the activities of individual companies and general market and economic conditions.

A “value” style of investing emphasizes undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on “value” equity securities are less than returns on other styles of investing or the overall stock market.

Although subject to the risks of common stocks, low volatility stocks are seen as having a lower risk profile than the overall markets. However, a fund that invests in low volatility stocks may not produce investment exposure that has lower variability to changes in such stocks’ price levels.

A “quality” style of investing emphasizes companies with high returns, stable earnings, and low financial leverage. This style of investing is subject to the risk that the past performance of these companies does not continue or that the returns on “quality” equity securities are less than returns on other styles of investing or the overall stock market.

The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”); however, the Fund may become “non-diversified,” as defined under the 1940 Act, solely as a result of tracking the Index (e.g., changes in weightings of one or more component securities). When the Fund is non-diversified, it may invest a relatively high percentage of its assets in a limited number of issuers.

While the shares of ETFs are tradable on secondary markets, they may not readily trade in all market conditions and may trade at significant discounts in periods of market stress.
