Recently we’ve coated the new SEC proposals and the importance of getting ticks right to make buying and selling cheaper for traders and scale back the price of capital for issuers. Immediately we spotlight how the SEC’s tick proposals influence ETFs.
As we all know, ETF spreads are different. Being each a portfolio and a inventory, with arbitrage obtainable, quite a lot of ETFs have tighter spreads than a equally liquid or equally priced inventory. That’s one cause why the SEC’s strategy to allocating tick teams based mostly on precise spreads (quite than inventory costs) is logical for ETFs. Nonetheless, it would additionally imply some comparable ETFs may have totally different tick sizes and totally different minimal spreads.
Primarily based on at present’s knowledge, we present that the totally different tick sizes gained’t actually matter to spreads.
That’s as a result of ticks in foundation factors are what traders ought to care about, and, as the information reveals, most shares gained’t want all their new ticks anyway. Utilizing a single ½ cent tick group, quite than the a number of teams within the SEC proposal, seems to be adequate to get rid of the tick constraint for almost all of ETFs.
In reality, what we see is totally different tick teams make spreads extra equal – in foundation factors – than the present 1-cent-fits-all regime.
How do ETFs commerce now (with a 1-cent tick)?
One of many issues with the 1-cent tick is that it turns into a mathematically costly unfold to cross as costs fall, resulting in extra queuing and longer instances to fill. And the extra liquid the ETF, the upper the value when that occurs. We are able to see that for all ETFs within the chart under.
Tick-constrained ETFs (inexperienced circles, and probably a few of the blue circles, too) are clearly caught on the diagonal line, the place NBBO spreads can’t get cheaper due to the 1-cent tick. A lot of these circles are additionally giant, indicating that this can be a extra widespread drawback for bigger, sometimes extra liquid, ETFs.

Understanding which tick buckets ETFs would possibly fall into
Eradicating the tick constraint ought to enable spreads in tick-constrained ETFs to fall.
Understanding which tick teams ETFs would possibly fall into requires us to forecast the tightest unfold a inventory might have – regardless of quoted spreads (by definition) being restricted to 1.0 cent.
To try this, we take a look at efficient spreads, which already keep in mind fills contained in the NBBO. That provides us a greater concept of which tick buckets ETFs would possibly lastly commerce at. We present the efficient spreads (in cents) vs. common spreads (in foundation factors) in Chart 2 under. We additionally shade by the SEC’s proposed tick teams.
Chart 2: ETF common spreads and efficient spreads coloured by proposed tick regime
Including up all of the tickers in every shade group, we see that:
- 717 ETFs could be positioned into the $0.001 or $0.002 tick bucket (that means they’ve a ramification beneath 1.6 cents).
- One other 874 ETFs that commerce with spreads between 1.6 cents and 4 cents now may have their tick lowered to ½ cent.
- Moreover, 1,418 ETFs that commerce with spreads greater than 4 cents large at present will maintain their 1-cent tick.
Chart 3: Variety of ETFs in every tick group proposed by SEC (based mostly on efficient spreads now)
What would possibly sub-penny ticks do to ETF spreads?
Replotting the information from Chart 1 however utilizing efficient spreads, we see what eradicating the tick constraint would possibly do to ETF buying and selling:
- All of the inexperienced ETFs are in a position to fall under the 1-cent tick (black line) that they commerce at now. Nonetheless, only a few appear to really want lower than a ½ cent tick (orange line) to commerce effectively.
- Among the blue ETFs seem like they may additionally commerce under the 1-cent tick (black) line. Nonetheless, none fall under the ½ cent tick (orange) line.
- Apparently, the information additionally reveals that ETF issuers are a lot better at “proper pricing” their ETFs for buying and selling than corporates appear to be, as most shares are buying and selling near their “optimum” unfold (Some blue and all of the orange dots, with a cluster of dots round $25 giving a 4-basis level unfold).
Chart 4: ETF efficient spreads by worth, coloured by proposed new tick teams (with traces exhibiting the efficient value of 1 new tick)
Specializing in particular ETF rivals
We are able to filter the information from Chart 4 to check comparable ETFs.
First, let’s take a look at the 150 most liquid ETFs. What the information reveals is that:
- Most find yourself within the 1/tenth cent tick group (inexperienced circles), particularly these with decrease costs. Nonetheless, none are anticipated to see spreads fall sufficient to commerce near a 1/tenth cent unfold (inexperienced line).
Which means each one of these ETFs will commerce with a number of tick increments inside their NBBO. Extra increments contained in the NBBO ought to decrease the price of queue leaping (for instance, the price of 1 tick in a $50 ETF falls from 2bps to 0.2bps), however it could additionally improve the usage of odd-lots (even within the new MDI-round-lot regime) and is nearly sure to increase message site visitors and reduce the resting time of ETF quotes.
- Most of the highest-price ETFs (proper aspect of the chart) solely qualify for the 1/5-cent tick group (blue circles). This group consists of ETFs like SPY, QQQ, VTV, IWM, and GLD, that are very liquid, however, because of larger costs, have very low tick prices even at present.
For instance, probably the most liquid inventory within the U.S. market, SPY (at $400), sees the price of 1 tick fall from 0.25bps to 0.05bps, though its unfold now could be nearer to 0.33 foundation factors.
Though, we observe that many of those are additionally affected by the acceleration of recent spherical lot guidelines, the place the ETFs above $250 will see a brand new spherical lot at 40 shares, which can additionally tighten spreads.
- Different (principally high-priced) ETFs which commerce with spreads 2-4 cents large at present (properly above the black 1-cent line) can be allotted to the ½-cent tick (orange circles). Arguably, these ETFs have already got an optimal price and tick today, and the SEC proposal might go away them with “too many ticks” by rising their unfold from 2-4 ticks to 4-8 ticks.
For instance, VOO trades at a median efficient unfold of three cents, giving it a 3-tick unfold. Beneath the brand new regime, VOO may have a smaller ½ cent tick. Nonetheless, a smaller tick than unfold doesn’t assist compress the unfold now, so we count on its common unfold to stay round 3 cents or 6 ticks large (6 x ½ cent tick = 3-cent unfold).
Regardless of all the brand new tick teams, knowledge means that few ETFs might have lower than a ½-cent unfold (orange line). Even SPY, probably the most liquid inventory on this planet, trades with an efficient unfold of 0.32 foundation factors. That’s larger than the orange line (1/2 cent) from $100 and above the even the blue line (1/fifth cent) above $50.
Chart 5: Liquid ETFs beneath the SEC’s proposed tick teams
Some ETF issuers are involved about aggressive inequities, pondering some ETFs may have a smaller tick than others, which can make traders and merchants want the ETF with the smaller tick as a result of it’s cheaper to commerce.
Nonetheless, the information appears to point that the brand new ticks truly make markets extra equal (as spreads ought to have the ability to fall to extra comparable ranges in foundation factors, no matter inventory worth).
For instance, if we evaluate GLD and IAU (each Gold ETFs):
- GLD has a excessive share worth (round $200), giving it a tick that’s 0.5-basis factors large. Information suggests it might be allotted to the 1/fifth cent tick – giving it round a 0.1-basis level tick. Nonetheless, buying and selling knowledge suggests it’s unlikely to commerce a lot inside a 0.8-basis level unfold (or 8 x 1/5 cent ticks = 0.8 foundation factors).
- IAU has a decrease share worth (round $40), giving it a tick round 2.5-basis factors large.
Information suggests it might possible be allotted to the 1/tenth tick group – giving it a 0.25-basis level tick. That will enable it to commerce with a ramification as tight as GLD (3 x 1/tenth cent ticks = 0.75 foundation factors). Though buying and selling knowledge suggests, regardless of that, it’d nonetheless commerce with a 1.5-basis level unfold (6 x 1/10 cents large).
We might additionally take a look at these aggressive dynamics by evaluating all of the ETFs investing in large-cap U.S. equities (Chart 6 under).
For instance, SPY (blue) may have a smaller tick than IVV and VOO (orange) though they’re all S&P500 ETFs. Nonetheless, these ETFs all have the identical costs and the identical 1-cent tick now, indicating the tick constraint doesn’t widen spreads within the orange tickers. Buying and selling knowledge additionally means that none of those ETFs are more likely to commerce tick constrained even with a ½ cent tick, as not one of the circles are a lot under the black 1-cent line).
So, the truth that the SEC has allotted all three to have ticks smaller than ½ cent appears extra more likely to go away all of them buying and selling a number of ticks large. In actuality, the consequence could be much like how issues work now – the place all three ETFs have totally different spreads (in cents) though all of them have the identical tick measurement (in cents and foundation factors).
One other approach to consider that is to take a look at SQQQ, TQQQ and QQQ (all Nasdaq 100).
- SQQQ and TQQQ are probably tick constrained now. With a 0.8-cent efficient unfold, their inexperienced circle sits properly under the black 1-cent tick line. Nonetheless, their decrease inventory worth (round $30) means a 1-cent tick provides to a 3 basis-point tick. The foundations counsel they are going to be allotted a 1/tenth cent tick, eradicating the tick constraint. However buying and selling knowledge suggests they may nonetheless solely commerce all the way down to a 0.8 cent unfold (8 x 1/tenth cent), giving them a 2.5-basis level unfold.
- In distinction, QQQ, because of its larger inventory worth (round $300), now has a tick round 0.7 foundation factors. Buying and selling knowledge means that QQQ can be allotted a 1/fifth cent tick however would possibly nonetheless commerce 1.2 cents large (6 x 1/5 cent tick).
Regardless of that, the totally different tick buckets enable these ETF spreads to grow to be extra equal, not much less.
Chart 6: Giant-cap ETFs beneath the SEC’s proposed tick teams
One factor that stands out when evaluating Charts 5 and 6 is that lots of the inexperienced circles from Chart 4 are lacking in Chart 6. The rationale for that’s in Chart 7 under.
The info suggests a number of the tick-constrained ETFs are bond ETFs.
This is sensible, though many are priced between $50-$100 (giving them a 1-cent tick = 1-2 foundation factors), bonds sometimes have decrease volatility, so spreads must be simpler to seize for market makers. In a aggressive market, that ought to make spreads tighter (even the place the underlying could be costlier to hedge).
That’s precisely what we see. In reality, it appears that almost all of ETFs that could be tick-constrained at a ½ cent tick – buying and selling under the orange line – are bond ETFs.
Even then, lots of the ETFs within the orange group (which commerce with spreads 1.6 – 4 cents large now) are unlikely to commerce with spreads tighter than 1 cent within the new setting no matter having extra ticks.
Apparently, regardless of many bond ETFs being tick constrained (inexperienced), issuers haven’t achieved reverse splits (to boost the value and scale back the price of a 1-cent tick), indicating that traders aren’t sad with a minimal 1-basis-point tick now – black line at $100, the place lots of the bigger ETFs (bigger circles) sit.
Notably, this chart additionally means not one of the bond ETFs are impacted by the acceleration of MDI spherical heaps, as none have costs over $250, the place spherical heaps shrink to 40 shares.
Chart 7: Company and authorities ETFs beneath the SEC’s proposed tick teams
Wish to study extra?
Briefly, what we see right here is that breaking the tick (by forming totally different tick teams based mostly on how ETFs commerce) would possibly truly make ETFs extra (not much less) equal.
Nonetheless, the traces within the charts above additionally appear to point that only a few (if any) ETFs want a 1/fifth cent tick in an effort to commerce effectively, even supposing ETFs sometimes have tighter spreads than shares.
With about 215 totally different issuers and roughly 3,000 lively totally different ETFs (as of March 2023) available in the market now, it is arduous to point out how all ETFs are impacted (even with all our labeled dot-plot charts above).
