This blog post is relevant to institutional investors interested in trading exchange-traded funds (ETFs) in significant volume. Individual investors do not always have access to liquidity providers to trade ETFs as referenced below.
What if I told you that a large $500 million order and a smaller $1.2 million order traded in the same ETF, but one executed around the bid/ask spread
and the other drove up the ETF price 84 cents, or almost 5%. Could you guess which trade was responsible for each outcome? The answer may surprise you. The $500 million notional block
, and a small order of $1.2 million notional block pushed the WisdomTree Brazilian Real Fund (BZF)
price 5% away from its underlying value
. The trades were done on different days and times, but the price of the ETF and its trading characteristics were similar. So what was the difference between the two trades?
On October 9, 2013, a 27-million-share block order
worth approximately $500 million executed inside the bid/ask spread of BZF. You can see the trade in the highlighted area in figure 1.
The client who initiated that trade was able to work with an ETF liquidity provider
who had the ability to access the underlying basket
in the primary market
on behalf of the client. It is important to remember that an ETF is at least as liquid
as its underlying securities, regardless of the average daily volume
. That demonstrates the beauty of the open-ended ETF structure and its ability to create
new shares and redeem shares daily. This trade was successful from an execution standpoint because the client worked together with their trading partners on a best execution strategy.
On the other side of the execution spectrum, another investor entered a 70,000-share ($1.2 million notional value) market order
in BZF on November 13, 2014, just before 3:39 p.m. ET. This resulted in a quick spike up in the price of the ETF, as you can see in figure 2.
In this second example, the order book
, or depth of the bids
of the ETF trading on the exchange, handled a market order of this size in an inefficient manner. The depth of bids and offers in an ETF order book is not always reflective of the liquidity of the underlying asset. While there is a lot of liquidity in Brazilian Real forwards, there are not a lot of resting orders
in the BZF order book. By definition, a “market order” is designed to buy or sell an investment immediately
at the best available price on the secondary market
and will not stop until completed. For this reason, the order for 70,000 shares swept up all available shares for sale until it was completed, which resulted in the price increasing by almost 5%. This was followed by the price of the ETF correcting back in line with the “indicative value” of the underlying basket. Figure 3, and the yellow arrow, illustrate how quickly the order was filled and how far the price moved to satisfy the 70,000- share buy order in the order book.
You may be wondering, “Isn’t there a market maker who is supposed to be providing liquidity so this doesn’t happen?” The answer is yes. A market maker provides a few thousand shares that he or she would be willing to buy or sell on either side of the quote. But a market order typically moves so fast that it may not provide enough time for the market maker to reload their bid or offer before the order has driven up the price significantly.
In summary, these two examples are something that all ETF investors can learn from. On the Capital Markets Team at WisdomTree, we try to be proactive in consulting with our clients on best- execution strategies. For larger orders, always look to work with a liquidity provider who can access the underlying basket on the clients’ behalf and provide execution close to the “fair value” of the ETF. Lastly, we encourage all investors to be sure to have a full grasp of the depth of the order book before implementing any market order. We hope this information helps investors in future ETF trades.

There are risks associated with investing, including possible loss of principal. Foreign investing involves special risks, such as risk of loss from currency fluctuation or political or economic uncertainty. This Fund focuses its investments in Brazil, thereby increasing the impact of events and developments associated with the region, which can adversely affect performance. Investments in emerging or frontier markets are generally less liquid and less efficient than investments in developed markets and are subject to additional risks, such as risks of adverse governmental regulation and intervention or political developments. Investments in currency involve additional special risks, such as credit risk and interest rate fluctuations. Derivative investments can be volatile, and these investments may be less liquid than other securities, and more sensitive to the effect of varied economic conditions. As this Fund can have a high concentration in some issuers, the Fund can be adversely impacted by changes affecting those issuers. Unlike typical exchange-traded Funds, there are no indexes that the Fund attempts to track or replicate. Thus, the ability of the Fund to achieve its objectives will depend on the effectiveness of the portfolio manager. Due to the investment strategy of this Fund it may make higher capital gain distributions than other ETFs. Please read the Fund’s prospectus for specific details regarding the Fund’s risk profile.
