ETFs have been one of many success tales of contemporary markets. Buying and selling round $100 billion per day with a weighted common unfold of simply 1.7 cents or 2.1 foundation factors (bps) initially of the 12 months. General, ETFs observe their web asset worth (NAV) extraordinarily effectively, permitting traders and merchants low-cost entry to diversified baskets and thematic exposures.
Let’s dive deeper into the information on how ETFs commerce for 5 enjoyable details on ETFs you won’t know.
1. ETF turnover has declined
Because the ETF trade matured it has seen some key developments:
- Extra Lively ETFs: With the creation of thematic, then sensible beta, then energetic, and now the approval of energetic non-transparent (ANT) ETFs, the normal hole between ETFs and basic mutual funds has closed.
- Longer maintain instances: As that has occurred, the holding instances of the common investor has climbed and new ETF traders are extra seemingly to make use of ETFs for long-term investing.
We will see this by taking a look at turnover (ETF buying and selling per 12 months/AUM, yellow line in Chart 1, and likewise in Chart Three right here).
Despite the fact that ETF buying and selling and liquidity has considerably elevated since 2004, the turnover has really declined. ETFs stay far more of a buying and selling automobile than basic mutual funds—with turnover round 5x per 12 months.
That shouldn’t be confused with the roughly 0.3x per 12 months that mutual funds flip over the shares of their portfolio, as most ETF portfolios seemingly commerce lower than their tickers too, particularly index ETFs the place portfolio turnover (earlier than creations and redemptions) is usually below 0.1x per 12 months.
It’s additionally fascinating to see that regardless of the spike in ETF turnover in the course of the credit score disaster, the proportion that ETFs comprised of complete market buying and selling didn’t spike (blue line) as inventory buying and selling elevated in the course of the credit score disaster.

2. ETFs have tighter spreads than shares
We’ve proven for firm shares that liquidity is a serious determinant of a shares unfold.
The identical holds true for ETFs (Chart 2). However knowledge exhibits that ETFs usually have even tighter spreads than shares with the identical liquidity.
Chart 2: ETF spreads are decrease than shares of comparable liquidity
There are good causes for that. For a begin, an ETF represents a portfolio of shares with their very own underlying liquidity and spreads. Usually the liquidity of the portfolio is multiples of the liquidity of the ETF.
In actual fact research have discovered that just about no ETF trades anyplace close to as a lot as its underlying portfolio. That’s even true of essentially the most liquid ETFs:
- Essentially the most liquid ETF (SPY) trades $22 billion per day, however holds shares that commerce nearer to $170 billion per day.
- The subsequent most liquid ETF, QQQ, really trades lower than AAPL or AMZN, two of its largest holdings.
3. Only a few ETFs are priced over $100 per share
After all, Chart 2 reminds us of the work we have now achieved on the excellent inventory worth and the necessity for inventory splits for corporates. There at the moment are 228 S&P500 corporations, or 45%, with costs over $100. These “excessive priced” corporations typically commerce with spreads a number of ticks extensive and with odd tons offering the true BBO more often than not.
Nevertheless, ETFs are completely different!
Information exhibits that solely 8% of ETFs are priced over $100 per share. Importantly, the common liquidity of these ETFs is $403 million per day so most of these ETFs even have the liquidity to help tight spreads and excessive costs. That may be seen by the small circles (unfold in cents) in Chart 2.
In actual fact, round half of all ETFs are priced within the buying and selling “candy spot”, between $20 and $50 per share, the place one tick represents 2 bps to 5bps. That is sufficient to entice quotes, however not so massive as to discourage buying and selling.
That’s not stunning given one of many major features of ETF issuers is to reduce buying and selling prices and supply liquidity; it appears ETF issuers already know on how vital tradability is.
Chart 3: The vast majority of ETFs are round $25 per share, priced for tradability
4. Creations and redemptions are a small fraction of inventory buying and selling
Though ETFs are constantly 25% of market-wide worth traded, it’s deceptive to say ETFs trigger shares to commerce anyplace close to that a lot.
That’s partly as a result of many ETFs really observe bonds or worldwide shares or commodities. However it’s additionally as a result of ETFs have a lot tighter spreads than their underlying portfolio of shares (Chart 2). In actual fact some research have discovered that ETF costs are normally a lot cheaper than buying and selling the underlying basket that inventory arbitrage (promoting the ETF and shopping for shares, or vice-versa) is unprofitable. That’s very true for essentially the most liquid ETFs which (as Chart 2 exhibits) have the tightest spreads.
One other solution to present that is to have a look at creations and redemptions every day.
Creations and redemptions normally happen when liquidity suppliers have purchased (or bought) the underlying shares to hedge their ETF trades, whether or not with purchasers or as a result of the ETF was wealthy (or low-cost) sufficient to arbitrage. A creation permits the market maker to ship their lengthy inventory place to the issuer and obtain new ETF shares in return. That neutralizes the arbitrage place, eliminating stock prices on an arbitrage; or the ETF might be delivered to straight the shopper cheaper than the ETF was buying and selling.
Chart 4a: ETF creations enable a market maker to change hedged inventory positions with the issuer for brand spanking new ETF shares which additionally reduces their web stock (web place)
Annually creations and redemptions quantity to roughly $2.Eight trillion each year. That feels like so much, however over a 12 months it’s simply 3% of U.S. inventory buying and selling, which provides to round $59 trillion of shopping for and promoting annually.
Why concentrate on shopping for and promoting? Regardless of the expansion from web inflows to ETFs, creations and redemptions are near equal. Which means some replicate inventory shopping for whereas others replicate inventory promoting. So it’s extra appropriate to match ETF creations and redemptions to the gross shopping for and promoting of shares, which provides to virtually $120 trillion annually.
Chart 4b: ETF creations (and redemptions) are a fraction of ETF shopping for (and promoting), and even much less of gross inventory or futures buying and selling
5. Totally different ETFs are used for various issues
Retail traders, banks and hedge funds are all energetic customers of ETFs. That’s testomony to their low-cost spreads and deep liquidity and shut monitoring vs. web asset worth due to environment friendly arbitrage. However a deep dive exhibits that some ETFs are higher suited to hedge funds whereas others are most well-liked by particular person traders.
Chart 5 reveals the next about quick curiosity (as a share of AUM) and turnover:
- Most ETF have comparatively low quick curiosity and turnover near 1x.
- However round 100 ETFs have a lot larger turnover and likewise are inclined to have extra quick curiosity (the blue dots making the hockey-stick form of chart 5). Though these ETFs characterize simply 4% of all tickers they make up 85% of all ETF liquidity. These ETFs have a tendency to supply thematic and index exposures. They act like futures offering predictable issue publicity for low prices.
Hedge funds and banks are nearly all of traders doing quick promoting (thereby creating quick curiosity). Not surprisingly, they like very liquid, typically very low-cost to commerce, ETFs. In addition they have a tendency to carry them for shorter-term thematic exposures, rising their turnover.
Different ETFs which have larger proportion of retail participation and infrequently extra complicated portfolio development generally together with extra dynamic inventory selecting. That features lots of the sensible beta and extra energetic ETFs higher designed for longer-term holding and outperformance, as Chart Three right here additionally exhibits.

What does this all imply?
One of many nice options of ETFs is how effectively they work for thus many traders.
That’s a testomony to their low-cost spreads and deep liquidity and shut monitoring vs. web asset worth, which itself is due to environment friendly arbitrage and the creation and redemption course of.
However simply because ETFs commerce so much, doesn’t imply they make underlying shares commerce. There are sufficient consumers and sellers of many ETFs that they don’t commerce in a “inventory arbitrage” zone a lot in any respect.
That’s one thing the buying and selling knowledge additionally helps.
