Opinion: Commission-free stock-market trading on some platforms may be raising costs and volatility for all of us

The rising use of cost for order circulate in U.S. fairness markets could also be rising volatility and prices for all buyers by shifting a better share of cash from exchanges to market makers.

Fee for order circulate, or PFOF, drives some commission-free brokers’ orders to off-exchange market makers together with Citadel and Virtu relatively than conventional exchanges. Final yr the 12 largest U.S. brokerage corporations earned a mixed $3.8 billion from PFOF, up 33% from 2020, in response to data compiled by Bloomberg Intelligence launched Feb. 1.

This marked shift shouldn’t be underestimated. Gary Gensler, chairman of the Securities and Change Fee (SEC), stated in a speech in June 2021 that “[i]n January, practically half of the buying and selling curiosity within the fairness market both is in darkish swimming pools or is internalized by wholesalers.”

On the spot income

Orders from commission-free brokers have comparatively gradual transmission instances, making them enticing for off-exchange market makers. The longer it takes for orders to succeed in market makers, the better the chance that costs transfer. Consequently, there’s a greater alternative for market makers to ebook an on the spot revenue.

As a consequence of PFOF, the favored buying and selling app Robinhood

routes roughly 40% of its trades by solely three locations, all off-exchange market makers. Citadel alone executes 25% of the daily volume of U.S.-listed equity options and 28% of U.S. retail fairness trades.  

As a consequence of PFOF, an investor who locations a restrict order on a trending inventory or choice might discover themselves chasing the market or paying extra. Restrict orders can solely be executed at, or higher than, a specified worth. The orders, like market makers’ bid/ask spreads, present liquidity to different buyers who look to purchase or promote at one of the best obtainable worth referred to as “market orders.”

Off-exchange market makers use high-speed-trading expertise to execute orders in actual time. When the market strikes earlier than a restrict order arrives at an off-exchange market maker, the market maker is ready to execute on that worthwhile restrict order and ship orders which have moved farther from the market to an alternate. The market makers are allowed to place these successful positions on their very own books in a course of often called “internalizing.”

Within the instance above, the off-exchange market maker will internalize the shopper’s restrict bid at an on the spot revenue and ship the restrict supply to an alternate the place the investor must await the market to rise once more earlier than execution or change the order with a decrease restrict worth.

Order imbalances

Mixed with buying and selling algorithms, this observe might lead to extra synthetic order imbalances and better volatility for buyers. For instance, in a inventory trending down resulting from unfavorable information, off-exchange market makers may repeatedly internalize worthwhile trades in a inventory whereas passing unprofitable orders on to the exchanges. This may occasionally trigger unfilled promote orders to construct behind a falling inventory, whereas restrict purchase orders, having been internalized, aren’t obtainable to buyers trying to exit. That drives down the value artificially.

Fee-free brokers know that gradual order transmission can have an effect on their clients, however with PFOF they haven’t any incentive to prioritize velocity. With practically all their income coming from PFOF, they might properly have an incentive to make sure gradual transmission instances.

For instance, there are a number of indicators that Robinhood has ignored its comparatively gradual transition instances. Regardless of having founders who beforehand managed a high-frequency-trading hedge fund and began a agency that offered high-frequency-trading software program, experiences counsel Robinhood’s apps are noticeably gradual, leading to poor execution for his or her clients.

New entrants

The issue might worsen. When market construction permits insiders to revenue on the expense of retail buyers, it typically attracts new entrants. Different various buying and selling techniques are shifting into the U.S. retail market, together with a current announcement from Soar Buying and selling, and Revolut just lately introduced it’s providing commission-free buying and selling utilizing PFOF.  

Whereas this drawback continues to develop, the U.S. appears reluctant to ban PFOF even when research present particular person buyers typically have greater all-in prices with commission-free brokers relatively than conventional brokerage accounts.

In distinction, cost for order circulate is forbidden within the U.Okay. In November 2021, the European Union made a proper proposal to ban it.

Commenting on a possible SEC ban on PFOF, Citadel’s Ken Griffin stated on the Economics Membership of Chicago on Oct. 4: “Fee for order circulate is a value to me. So, when you’re going to inform me that by regulatory fiat that one in every of my main gadgets expense disappears, I’m OK with that.”

His assertion assumes these trades can be routed to Citadel with out such funds, which appears unlikely.

On the subject of eliminating their data benefit resulting from gradual knowledge transmission, these market makers grow to be overtly defensive. When the SEC authorized IEX’s “D Restrict” order sort, which was designed to provide buyers a method to purchase or promote shares on the alternate whereas defending buyers in opposition to unfavorable worth strikes (stale orders) resulting from slower knowledge transmission instances, Citadel objected and sued the SEC.

The historical past of corporations benefiting from retail buyers raises further crimson flags:

Regulators must ask:

  • Is the U.S. market construction, together with PFOF, which permits gradual transmission retail orders to be routed (for a charge) to high-speed-trading corporations, impacting the prices for all U.S. buyers?

  • In that case, given the checkered previous of trade breaches in transparency and finest execution, ought to regulators guarantee gradual retail order transmission is just not deliberately inbuilt to extend income for each commission-free brokers and off-exchange market makers?

Regulators such because the SEC, FINRA and state securities directors ought to use their powers to entry knowledge from exchanges, commission-free brokers and market makers.

Right this moment’s forensic market consultants are well-prepared to make use of this knowledge to investigate and reply these necessary questions. It doesn’t matter what closing choices regulators make, the outcomes of those inquiries would assist deliver again wanted investor confidence in U.S. markets.
