This article is relevant to financial professionals. If you are an individual investor, please inquire with your financial professional.

Most industry experts in ETF capital markets will preach a few core best trading practices and usually first on that list is “Avoid the first and last 15 minutes of the trading day.” Typically, this period is the most volatile time of the day, and spreads in the underlying baskets are widest. When spreads in the underlying stocks are wide, it translates to wider spreads in the ETF as well, which can lead to higher trading costs. But unless you model out the ETF basket for yourself, how can you know if this is true?

With the introduction of our new Estimated NAV Tool or eNAV, we are now providing unparalleled transparency into every ETF basket’s fair value. Historically, issuers were required to publish IOPV or indicative value, which showed the last traded price of the underlying basket in ETF terms. eNAV goes one step further and provides the bid and ask or current fair value spread of the underlying basket. The way we have built this exciting new tool allows investors to see how the basket spread changes throughout the course of the day, providing further transparency into WHY we lead with not trading during the first or last 15 minutes of the day.  

For example, in figure 1, you can see the eNAV or basket spread of the WisdomTree SmallCap Dividend Fund (DES) over the course of the day on March 26, 2021. As you can see, at the market open and market close, the basket spread is over two times as wide as it is the rest of the trading day. The reason for this is that at the open the underlying stocks are finding their equilibrium prices, and at the close, market participants are beginning to close their books for the day, thus widening out spreads in the underlying components.

In figure 2, we see the spread over the same period for the Fund itself. As expected, the Fund spread has a direct correlation to that of the underlying basket, trading wider during the first and last 15 minutes of the trading day.

Transparency is one of the cornerstones of the ETF structure. We believe eNAV only improves on this aspect and adds to the overall ETF investor experience. Next time you hear someone say “don’t trade ETFs during the first or last 15 minutes of the trading day,” don’t just take their word for it, see it for yourself with eNAV. It might just save you money.
