A trader runs wash trades between two accounts he controls in a stock that trades only over the counter and is not registered on any national exchange. The SEC charges him under Section 9(a)(1) of the Exchange Act. Which statement about that charge is correct?

The charge is available: Section 9 reaches any security other than a government security, exchange-registered or not

The charge fails: Section 9 applies only to trades executed through a registered broker-dealer, not for one's own account

The charge fails: Section 9 reaches only securities registered on a national exchange, so the SEC must use Section 10(b)

The charge is available only if his trades moved the price, since Section 9(a)(1) targets price effects, not volume

What must be proved to establish a violation of one of the specific manipulation prohibitions in Section 9 of the Securities Exchange Act?

The prohibited conduct by itself, since Section 9 imposes strict liability on traders

Both the prohibited conduct and the manipulative intent that lay behind it

Manipulative intent together with a resulting loss to an identified investor

The conduct plus a price movement of a minimum size fixed by SEC rule

A trader buys an exchange-listed stock in a run of purchases at rising prices, aiming to draw other buyers in. Every trade is a genuine purchase from an unrelated seller. His counsel argues Section 9 cannot apply because beneficial ownership really changed hands. Is that right?

Yes — Section 9 reaches only wash sales and matched orders, in which beneficial ownership never actually changes hands between the parties

Yes — trades with a genuine change of ownership are lawful market activity, whatever the buyer's motive for them

No — Section 9 separately bars a series of transactions that raises a price in order to induce others to buy

No — Section 9(a)(4) treats a run of rising purchases as a misleading statement made to induce other investors to buy

Which profile describes the stock a pump and dump scheme typically targets?

A microcap issuer with a small public float, little analyst coverage and sparse regulatory disclosure

A large-cap issuer with heavy daily volume, whose price can absorb promotional buying without strain

A mid-cap issuer with actively traded listed options, which let the promoters lever the price move

A newly listed issuer with wide analyst coverage, whose research reports the promoters can quote

A group buys a large stake in a thinly traded stock at low prices, then floods social media with claims of an imminent acquisition, and the price climbs. What happens next in a pump and dump, and who bears the loss?

The group holds through the acquisition announcement, and the short sellers who bet against the claims lose

The group sells into the inflated price, the promotion stops, and late buyers hold shares that collapse

The group buys more as the price climbs, and the issuer bears the loss when its shares are later delisted

The group sells gradually over months, and the price settles at fair value so that no investor is harmed

A trader buys and sells the same stock almost simultaneously between two accounts he beneficially owns, repeating it all day. No outsider ever trades with him. How does this harm other investors?

Each round trip takes shares out of the public float, leaving outsiders unable to buy at any price

His trades are executed ahead of customer orders, so outsiders receive worse prices on their own fills

The trades shift his losses into the accounts of other customers who hold positions at the same firm

They read the inflated volume as a sign of liquidity and momentum and are drawn into the stock

Two traders at affiliated firms agree in advance that one will sell 50,000 shares of a listed stock at $12 at the moment the other enters a buy of the same size and price. Buyer and seller are different beneficial owners. Does that difference take the trades outside the Exchange Act's ban on wash sales and matched orders?

No — orders entered knowing that substantially the same opposite orders will be entered by an affiliated party are matched orders

Yes — the prohibition reaches only trades in which a single beneficial owner sits on both sides of the transaction

No — any trade between affiliated firms is a matched order, whether or not the two orders were coordinated in advance

Yes — trades between affiliated firms are internal transfers, which the prohibition expressly exempts from its reach

A trader wants to buy a stock below its current price. Which course of conduct would be spoofing?

He posts large buy orders below the bid, lets them execute in full, and later sells the shares at a higher price

He posts large sell orders above the offer, waits for bids to drop, cancels the orders and then buys lower

He buys in one account and sells in another he controls, then buys more once the volume draws in sellers

He enters one small buy order below the bid, then cancels it an hour later when no seller has filled it

How does the legal basis for prohibiting spoofing differ between commodity futures markets and securities markets?

In securities Exchange Act Section 9 names spoofing expressly; in futures it is reached through general anti-fraud provisions

Both markets prohibit spoofing through a single shared provision that the Dodd-Frank Act added to the Exchange Act

In futures the Commodity Exchange Act names spoofing expressly; in securities it is reached as a deceptive device under Section 10(b)

In futures spoofing is barred by CFTC guidance alone; in securities it is barred by FINRA rules with no statutory basis

One trader places a large buy order intending to fill it, then cancels it minutes later after news moves the market against him. Another places an identical order intending all along to cancel it before it fills. What separates the two in law?

The first is spoofing, because his cancellation followed a price move that the order itself may have caused

Nothing — cancelling a large displayed order after the market has moved is spoofing in either trader's case

Neither is spoofing, since the term covers orders placed and cancelled by an automated trading algorithm

The second trader placed his order with intent to cancel before execution, the defining element of spoofing

A member firm's surveillance for layering reviews customer order flow but excludes the firm's own proprietary trading desk. How does FINRA Rule 3110 treat that design?

As deficient, because the review must be reasonably designed to identify layering in both customer and proprietary trading

As adequate, because proprietary trading is supervised under separate capital rules rather than through Rule 3110 review

As adequate, provided the proprietary desk certifies each quarter that it placed no non-bona fide orders of its own

As deficient, because Rule 3110 requires a principal to pre-approve every layered order before it can be entered

Why can moving a security's closing price benefit a manipulator far beyond the value of the shares traded in the final minutes?

Closing prices fix the opening price of the next session, so any move carries over into the following day

Closing prices feed fund net asset values, derivatives settlement, performance benchmarks and margin requirements

Closing prices set the price at which all of the day's earlier trades are re-confirmed to customers

Closing prices are the only prices reported to the consolidated tape, so they define the day's recorded volume

A trader holds call options struck at $50 that expire today. With the stock at $49.80 in the last minutes of trading, he buys shares aggressively until it closes at $50.10. How does FINRA's guidance characterise this?

As wash trading, because his purchases create volume without any change in the beneficial ownership of the options

As a permitted hedge, because buying the underlying shares offsets the delta risk of a long call position as it approaches expiration

As cross-product manipulation: trading the stock to push the close past the strike so his options finish in the money

As lawful price discovery, because his purchases were genuine, fully executed at prevailing market prices, and hid nothing from anyone

An index fund must buy a large block of a stock at the close because the stock joins its benchmark that day, and the fund's orders lift the closing price. Is that marking the close?

No — index funds are exempt because their trading is dictated by the benchmark's published rules

Yes — any trade at or near the close that moves the closing price counts as marking the close

Yes — a single buyer moving the close is marking it once the order exceeds the stock's normal volume

No — marking the close requires trading for the purpose of artificially influencing the closing price

Churning is a FINRA conduct violation. In what sense is it also treated as a form of market manipulation?

It distorts trading activity in a customer's account to benefit the broker at the customer's direct expense

It moves the price of the securities traded by enough to mislead the wider market about real demand

It creates false volume in the securities traded, because the customer and broker are the same owner

It requires the broker to post false quotations, which misstate supply and demand to other dealers

FINRA's Annual Regulatory Oversight Reports criticise how some broker-dealers calibrate their manipulation surveillance thresholds. Which settings do they identify as a deficiency?

Only thresholds set too low, since excess alerts bury the genuine cases

Thresholds set too high and thresholds set too low, both alike

Only thresholds set too high, since a low threshold merely adds alerts

Thresholds that depart from the uniform levels FINRA publishes for members

How does FINRA's Market Regulation department come to conduct surveillance of trading on national securities exchanges that FINRA itself does not operate?

Exchange Act Section 9 assigns surveillance of exchange-registered securities to FINRA directly by statute

Every exchange is a FINRA member firm, so trading on it falls under FINRA's own membership rules automatically

The SEC transferred its market surveillance function to FINRA when the Market Abuse Unit was closed down

FINRA's Market Regulation department's surveillance turns up a pattern of manipulative trading by a registered representative of a member firm. Where does Market Regulation send the case?

To the Department of Justice, because manipulation is pursued only as a criminal offence

To the SEC, because only the Commission may bring disciplinary proceedings for market manipulation

To the exchange whose market was watched, which disciplines the representative under its own rules

To FINRA's enforcement division, which brings disciplinary proceedings against those responsible

Does the prohibition of wash trading extend beyond equities to commodity futures and options?

Yes, but only through Section 9(a)(1) of the Exchange Act, which the SEC enforces in those markets as well

Yes: the Commodity Exchange Act prohibits it in futures and options, and the CFTC has brought many actions

No: wash trading is a securities offence under Section 9(a)(1), which does not reach any commodity market

No: futures trades clear through a central counterparty, so a wash trade there changes no one's position

A layering trader places non-bona fide orders to bait other participants and then executes a genuine trade. At what point does the trader cancel the non-bona fide orders?

Not until the close, so that they also influence the closing auction price

Never, since they are left to execute against the participants they attracted

Immediately after the genuine trade executes, their work as bait now done

Before the genuine order is entered, so that none of them is ever exposed to a fill

Layering is a specific form of spoofing. How does the way a layering trader displays non-bona fide orders differ from a single large spoof order?

Orders are split between both sides of the market at one price, so the book shows interest each way at once

One order is shown at a price far from the market, where it can never be reached before it is cancelled

Orders are routed to several exchanges at one price, so the consolidated book shows the same interest repeated

Several orders are stacked at different price levels on one side, in a ladder of progressively more aggressive prices

A broker trades a customer's account frequently. What separates churning from appropriate active management of the account?

Trading that is excessive and driven by the broker's commissions rather than the customer's investment objectives

Trading that loses money overall, active management being judged by whether the account beats its benchmark

Trading in more than one security each day, active management being confined to a single daily transaction

Trading without the customer's written approval of each order, active management requiring that consent

An employee gives the SEC original information about a manipulation scheme, and the enforcement action it leads to collects $4 million in monetary sanctions. Under SEC Rule 21F, what award may she receive?

Up to $400,000, the award being capped at ten percent of the sanctions collected

Between $400,000 and $1.2 million, ten to thirty percent of the sanctions collected

Between $1.2 million and $2 million, thirty to fifty percent of the sanctions collected

Nothing, since awards are paid only where the sanctions collected exceed $5 million

How has the way pump-phase promotions reach investors changed from earlier schemes to modern ones?

From printed investment newsletters and radio spots to registered research reports that promoters now buy from broker-dealers' analysts

From social media posts and online forums to private telephone calls, regulators having driven the promoters off every public platform

From boiler-room calls, spam and fake press releases to social media, online forums and paid posts posing as independent analysis

From newspaper advertisements and mailed circulars to falsified issuer filings, which the promoters now lodge with the SEC directly

What criminal exposure does an individual face for a wilful violation of the Exchange Act prosecuted under Section 32, as in a pump and dump?

Imprisonment of up to five years, with fines of up to one million dollars

A fine of up to five million dollars, prison terms being reserved for repeat offenders

Imprisonment of up to ten years, with fines of up to twenty-five million dollars

Imprisonment of up to twenty years, with fines of up to five million dollars

Navinder Singh Sarao, the London-based trader prosecuted in connection with the May 6, 2010 Flash Crash, was found to have done what?

Run wash trades in S&P 500 index options between accounts he controlled to inflate volume

Marked the close in the largest S&P 500 stocks to move the index's settlement price

Spread false rumours of a bank failure on social media to drive the index futures lower

What do FINRA's surveillance systems monitor for evidence of spoofing?

Executed trades alone, since a cancelled order leaves no record that surveillance is able to review

The patterns in which orders are entered and then cancelled in the electronic order book

Traders' written statements of intent, which members must file before they enter any large order

Closing prices alone, since spoofing can be detected only through its effect on the official close

A broker-dealer surveils its customers' equity trading and their options trading in two separate systems that never compare the two. How do FINRA's Annual Regulatory Oversight Reports regard that arrangement?

As adequate, since FINRA's guidance asks only that each market be surveilled on its own terms

As adequate, cross-market manipulation being for the SEC to detect rather than a member firm

As a common deficiency: surveillance linking the equity and derivatives markets is absent

As a deficiency only if the firm also trades options for its own proprietary account

What does an SEC disgorgement order require of a manipulator?

Payment of three times the profits gained, in place of any civil penalty

Repayment to each investor of the full price paid during the scheme

Surrender of the profits on trades made after the investigation opened

Surrender of all the profits derived from the scheme, plus pre-judgment interest

Market Manipulation: Schemes, Laws and Penalties

What Is Market Manipulation?

Market manipulation is the intentional use of deceptive, artificial, or fraudulent tactics to distort the price or trading volume of a security — creating a false impression of market activity, supply, demand, or value — for the purpose of profiting at the expense of other market participants who act on the misleading signals. It is one of the most seriously treated categories of securities law violation in the United States, carrying civil and criminal penalties under the Securities Exchange Act of 1934, and it appears throughout the SIE, Series 7, and Series 65 examination curricula as a core prohibited practice that registered persons must understand and avoid.

The Legal Framework — Two Statutory Pillars

Market manipulation in securities markets is prohibited under two primary statutory provisions of the Securities Exchange Act of 1934 that operate together to cover the full range of manipulative conduct.

Section 9 of the Securities Exchange Act prohibits specific manipulative acts in any security other than a government security. Before the Dodd-Frank Act of 2010 its prohibitions reached only securities registered on a national exchange; the Act replaced that limit, so Section 9 now reaches securities traded only over the counter as well. Section 9(a)(1) prohibits wash sales and matched orders — transactions that create a false appearance of active trading without any genuine change in beneficial ownership.

Section 9(a)(2) prohibits a series of transactions that raise or depress the price of a security for the purpose of inducing others to buy or sell. Section 9(a)(4) prohibits making false or misleading statements about a security to induce transactions. Each of these provisions targets specific manipulative mechanisms and requires proof of both the conduct and the manipulative intent.

Section 10(b) of the Exchange Act is the broader, catch-all antifraud provision prohibiting any manipulative or deceptive device or contrivance in connection with the purchase or sale of any security. SEC Rule 10b-5, promulgated under Section 10(b), extends this prohibition to any act, practice, or course of business that operates as a fraud or deceit upon any person in connection with a securities transaction.

Together, Section 10(b) and Rule 10b-5 provide the regulatory and enforcement foundation for prosecuting manipulative trading conduct that may not be specifically enumerated in Section 9.

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 strengthened anti-manipulation enforcement by creating new civil penalty authority and expanding SEC whistleblower protections and financial rewards for information leading to successful enforcement actions. Under SEC Rule 21F, whistleblowers who provide original information about securities violations resulting in sanctions exceeding one million dollars may receive awards of ten to thirty percent of the monetary sanctions collected.

The Major Categories of Market Manipulation

Market manipulation manifests in several distinct forms, each involving a different mechanism for distorting prices or volume. FINRA’s guidance on manipulative trading identifies the following as the primary categories of concern for broker-dealer supervisory programmes.

Pump and Dump

The pump and dump scheme is among the oldest and most frequently prosecuted forms of market manipulation, typically targeting microcap stocks with small public floats, limited analyst coverage, and sparse regulatory disclosure. The scheme operates in two phases.

During the pump phase, the manipulators accumulate a large position in the target stock — often purchased at low prices before the promotion begins — and then disseminate false or misleading promotional materials designed to generate artificial investor interest.

These promotions historically arrived through cold-call boiler room operations, spam email campaigns, and fabricated press releases. In the modern era they typically appear through social media posts, online bulletin boards, cryptocurrency forums, and paid promotional content disguised as independent investment analysis. The false claims attribute extraordinary business prospects, imminent acquisitions, or breakthrough products to the target company, generating buying interest that drives the price upward.

During the dump phase, the manipulators sell their accumulated position into the artificially elevated market — realising large profits at prices far above what the company’s fundamentals would support. The selling floods the market with supply, the promotional materials stop, and the stock price collapses. Investors who purchased during the pump phase are left holding shares that have lost most or all of their value, having effectively transferred their capital to the manipulators.

Section 10(b) of the Exchange Act and SEC Rule 10b-5 provide the primary enforcement basis for pump and dump prosecutions, because the promotional materials containing false statements satisfy the fraud element. Criminal prosecution under Section 32 of the Exchange Act for wilful violations carries penalties of up to twenty years imprisonment and fines up to five million dollars for individuals.

Wash Trading

Wash trading is the buying and selling of the same security simultaneously or nearly simultaneously using different accounts, often controlled by the same beneficial owner or coordinated group, for the sole purpose of generating artificial trading volume. Wash trades do not involve any genuine change in beneficial ownership — the seller and the buyer are ultimately the same party — but they create the appearance of high trading activity that can attract legitimate investors who rely on volume as an indicator of liquidity and momentum.

Section 9(a)(1) of the Exchange Act specifically prohibits wash sales and matched orders — transactions in which purchase and sale orders are entered with knowledge that substantially the same orders have been or will be entered by or for the same or different parties, matched orders being orders of substantially the same size, at substantially the same time and at substantially the same price.

Wash trading is prohibited both in equities and, under the Commodity Exchange Act, in commodity futures and options, with the CFTC having brought numerous wash trading enforcement actions against commodity market participants.

Spoofing

Spoofing is the placement of large buy or sell orders in an electronic trading system with the intent to cancel those orders before they execute — using the visible presence of the order in the public order book to create a false impression of supply or demand that induces other market participants to trade at artificially influenced prices.

A spoofer who wants to buy shares at a lower price places large sell orders above the current offer, creating the false appearance of substantial selling pressure. Other market participants, seeing what appears to be heavy supply entering the market, lower their bids in anticipation of a price decline. The spoofer cancels the fake sell orders — which were never intended to execute — and buys shares at the artificially depressed price. The fake orders served their purpose: inducing other participants to create a more favourable entry price for the spoofer’s genuine trade.

Spoofing in commodity futures markets is explicitly prohibited by Section 4c(a) of the Commodity Exchange Act as amended by the Dodd-Frank Act, which makes it unlawful to engage in any trading practice commonly known as spoofing, defined as bidding or offering with the intent to cancel before execution. In securities markets, spoofing is prohibited under Section 10(b) of the Exchange Act and Rule 10b-5 as a manipulative and deceptive device. FINRA’s surveillance systems monitor order entry and cancellation patterns for evidence of spoofing and refer cases to its Department of Market Regulation for investigation.

Navinder Singh Sarao — a London-based trader prosecuted in connection with the 2010 Flash Crash — was found to have used spoofing algorithms that placed and rapidly cancelled large orders in the E-Mini S&P 500 futures market, contributing to the market conditions that produced the extreme price dislocations of May 6, 2010. Sarao pleaded guilty to spoofing and wire fraud charges in 2016.

Layering

Layering is a specific form of spoofing in which a trader places multiple non-bona fide orders at several different price levels on one side of the market — typically in a ladder formation of progressively more aggressive prices — to create the appearance of deep market interest on that side, then executes a genuine trade on the opposite side at the price influenced by the layered orders, and finally cancels all of the layered orders immediately after the genuine trade executes.

FINRA’s guidance on manipulative trading specifically identifies layering as a category requiring robust supervisory surveillance, noting that layering activity involves placing non-bona fide orders on one side of the market to bait other market participants to react and trade with an order on the other side. FINRA Rule 3110 requires member firms to establish supervisory procedures that include a review process for transactions reasonably designed to identify layering and other forms of manipulative conduct in both customer and proprietary trading.

Marking the Close

Marking the close is the practice of executing transactions in a security at or near the close of trading for the purpose of artificially influencing the security’s closing price. Closing prices are used for a wide range of purposes — calculating the net asset value of mutual funds, settling derivatives contracts, benchmarking portfolio performance, and determining margin requirements. By influencing the closing price, the manipulator can affect these valuations in ways that benefit their portfolio positions.

FINRA’s guidance specifically lists marking the close as a form of cross-product manipulation in which transactions in a security are used to influence the price of an overlying options position — for example, buying shares aggressively in the last minutes of trading to push a stock price above an options strike price, converting the holder’s options from out of the money to in the money at the critical expiration settlement moment.

Churning

Churning is the excessive trading of a customer’s account by a broker primarily to generate commissions for the broker rather than to pursue the customer’s investment objectives. As covered in the entry on Churning in this dictionary, it is both a market conduct violation under FINRA Rule 2111 and a form of manipulation in the sense that it distorts trading activity for the benefit of the broker at the direct expense of the customer. The element of excessive trading that distinguishes churning from appropriate active management is tested directly on SIE and Series 7 examinations.

Regulatory Surveillance and Enforcement

Both the SEC and FINRA operate sophisticated automated market surveillance systems that monitor trading patterns, order entry and cancellation behaviour, and price movements in real time across national market system equities and listed options.

The SEC’s Office of Market Intelligence and its Market Abuse Unit analyse trading data for patterns consistent with manipulation and refer matters for formal investigation and enforcement. FINRA’s Market Regulation department conducts surveillance across the equity and options markets it oversees by contract with the national securities exchanges and refers manipulative trading cases to its enforcement division for disciplinary proceedings.

Civil penalties for market manipulation under Section 21A of the Exchange Act reach up to the greater of three times the profits gained or losses avoided. Criminal penalties under Section 32 for wilful violations include imprisonment of up to twenty years and individual fines of up to five million dollars. SEC disgorgement orders require manipulators to surrender all profits derived from the manipulative scheme, plus pre-judgment interest.

FINRA sanctions include substantial fines, disgorgement, suspensions, and permanent bars from the securities industry. FINRA’s Annual Regulatory Oversight Reports consistently identify manipulative trading surveillance as a priority examination area, noting common deficiencies in broker-dealer supervisory systems including surveillance thresholds set too high or too low, failure to monitor both customer and proprietary trading for manipulation patterns, and absence of cross-product surveillance linking equity and derivatives markets.

Examination Relevance and Key Takeaways

Market manipulation is tested on the SIE, Series 7, and Series 65 examinations as a core prohibited practice appearing in the context of securities law, regulatory violations, and supervisory obligations.

The key points to retain are these.

Market manipulation is the intentional distortion of a security’s price or trading volume through deceptive or artificial means, prohibited under Section 9 of the Securities Exchange Act of 1934 — which specifically prohibits wash sales, matched orders, and series of transactions to raise or depress prices — and under Section 10(b) and SEC Rule 10b-5 — which provide the catch-all antifraud prohibition on manipulative and deceptive devices in connection with securities transactions.

The five primary manipulation schemes are: pump and dump — artificially inflating prices through false promotional materials before selling into the inflated market, prosecuted under Section 10(b) and Rule 10b-5; wash trading — buying and selling simultaneously through related accounts to create false volume without genuine change in ownership, prohibited under Section 9(a)(1); spoofing — placing large orders with intent to cancel before execution to create false price pressure, prohibited under Section 10(b) in securities and explicitly under Section 4c(a) of the Commodity Exchange Act in futures markets; layering — placing multiple non-bona fide orders at different price levels to induce other participants to trade at manipulated prices; and marking the close — transacting at or near the close to artificially influence closing prices used for settlement, valuation, or derivative expiration purposes.

FINRA Rule 3110 requires member firms to establish supervisory procedures including surveillance systems reasonably designed to detect all categories of manipulative trading. Civil penalties reach three times profits under Section 21A of the Exchange Act. Criminal penalties under Section 32 reach twenty years imprisonment and five million dollars for individuals for wilful violations. SEC whistleblowers may receive awards of ten to thirty percent of sanctions above one million dollars under Rule 21F.
