All questions

Question 1

The illegal practice of a broker-dealer executing trades for its own account after receiving a large customer order but before that order is executed is a violation because:

  1. it violates the broker-dealer's duty of fair dealing with its customers. (correct answer)
  2. it always results in a loss for the customer.
  3. it is a form of freeriding under Regulation T.
  4. it guarantees a profit for the broker-dealer.
Explanation: Front running is a breach of the fiduciary duty that a broker-dealer owes to its clients. The firm is using confidential customer information for its own benefit, which is a violation of the principles of fair dealing and commercial honor, regardless of whether it results in a guaranteed profit for the firm or a loss for the customer.

Question 2

An investor purchases a stock in a cash account and sells it two days later, before having deposited the funds to pay for the initial purchase. This violation is known as:

  1. freeriding. (correct answer)
  2. kiting.
  3. layering.
  4. capping.
Explanation: Freeriding is a violation of Regulation T where an investor sells securities without paying for them. This is prohibited in a cash account. Kiting is a form of check fraud, layering is a stage of money laundering, and capping is a form of market manipulation to prevent a stock's price from rising.

Question 3

When regulators evaluate whether a registered representative has engaged in excessive trading, which factor is LEAST relevant?

  1. The customer's financial situation and investment objectives.
  2. The turnover rate within the customer's portfolio.
  3. The registered representative's overall production and ranking within the firm. (correct answer)
  4. The cost-to-equity ratio in the customer's account.
Explanation: The determination of churning focuses on the activity within the specific customer's account in relation to their profile. Factors like turnover rate, cost-to-equity ratio, and the customer's objectives are critical. The representative's overall ranking or production across all their clients is not a direct measure of whether one particular account was churned.

Question 4

'Pump and dump' schemes are most often perpetrated on which type of security?

  1. U.S. Treasury bonds.
  2. Shares of large-cap, well-known companies.
  3. Micro-cap stocks that are thinly traded. (correct answer)
  4. Shares of open-end investment companies.
Explanation: These schemes work best with securities that are illiquid and thinly traded, such as micro-cap or 'penny' stocks. It is much easier for manipulators to influence the price of such stocks with relatively small transaction volumes and misleading promotions.

Question 5

Which of the following activities is NOT considered a form of market manipulation?

  1. A market maker failing to honor its published quote for 100 shares.
  2. A large mutual fund selling a significant portion of its holding in a company, causing a temporary price decline. (correct answer)
  3. Two traders coordinating trades to create the appearance of active trading in a stock.
  4. Intentionally spreading false information about a company's financial health on an online forum.
Explanation: A large, legitimate transaction by an institutional investor, even if it affects the market price, is not considered manipulation. It is a normal market activity based on an investment decision. The other options describe backing away, wash sales, and spreading rumors, all of which are manipulative practices.

Question 6

The prohibition against front running is primarily concerned with a firm trading ahead of which type of order?

  1. Any order entered by a retail customer.
  2. An order from the firm's own CEO.
  3. A large block order that could reasonably be expected to impact the stock's price. (correct answer)
  4. An order that has already been partially executed.
Explanation: Front running rules are designed to prevent firms from taking advantage of their knowledge of large, market-moving orders from customers. Trading ahead of a small retail order that would have no market impact would not typically be considered front running.

Question 7

The prohibited practice of entering orders at or near the beginning of the trading day for the purpose of artificially influencing a stock's opening price is known as:

  1. freeriding.
  2. marking the open. (correct answer)
  3. front running.
  4. capping.
Explanation: Marking the open is a manipulative act where a trader attempts to influence the opening price of a security by entering a cluster of orders just as the market opens. It is the counterpart to marking the close.

Question 8

Which of the following actions by a registered representative is a legitimate market activity and NOT a form of manipulation?

  1. Creating the appearance of high trading volume by placing simultaneous buy and sell orders for a stock with no change in beneficial ownership.
  2. Advising a client to sell a large holding in a stock based on the firm's recently published, well-researched 'sell' recommendation. (correct answer)
  3. Telling a client an unverified rumor about a potential merger to encourage the client to buy the stock.
  4. Entering a large number of trades at the end of the day to influence a stock's closing price.
Explanation: Acting on legitimate, publicly disseminated research is a proper function of a registered representative. The other options describe manipulative acts: a wash sale (A), spreading rumors (C), and marking the close (D).

Question 9

Under Regulation T, what is the most likely consequence for a customer who engages in freeriding in a cash account?

  1. The account will be charged a penalty equal to the profits from the trade.
  2. The account will be frozen for 90 days, requiring payment upfront for any new purchases. (correct answer)
  3. The customer will be permanently barred from opening another brokerage account.
  4. The firm must file a Suspicious Activity Report (SAR) with FinCEN.
Explanation: The standard penalty for a freeriding violation is that the broker-dealer must freeze the customer's account for 90 days. During this period, the customer can still sell securities but must have sufficient cash in the account before any new buy orders can be entered.

Question 10

Under the Securities Exchange Act of 1934, prohibitions against market manipulation apply to:

  1. only securities listed on the NYSE and Nasdaq.
  2. only transactions conducted by FINRA member firms.
  3. all securities, including equities, bonds, and options. (correct answer)
  4. only initial public offerings (IPOs).
Explanation: The anti-fraud and anti-manipulation provisions of the Securities Exchange Act of 1934 are very broad and apply to the purchase or sale of virtually all types of securities in the secondary market, regardless of where they are traded.

Question 11

A promoter pays a rep to publish glowing "research" on a microcap without disclosing compensation, then both sell; which rule area is most clearly breached?

  1. Antifraud rules prohibiting misleading statements and omissions, including Rule 10b-5 (correct answer)
  2. Regulation D limits on accredited investor definitions
  3. SIPC rules on protection for commodity futures accounts
  4. Regulation A limits on secondary trading in listed stocks
Explanation: This question tests understanding of market manipulation practices within securities trading, focusing on identifying prohibited activities.

This highlights the breach of antifraud rules prohibiting misleading statements and omissions, including Rule 10b-5. The correct answer is A, as it accurately identifies the manipulation tactic used, aligning with industry definitions and regulatory standards. A common distractor is B, which fails because it misinterprets the violation as limits on accredited investors rather than fraudulent promotions, often misleading those unfamiliar with precise industry practices. To better identify such tactics, consider studying real-world cases and familiarizing yourself with regulatory guidelines. Practice distinguishing between legitimate trading strategies and manipulative actions by analyzing diverse scenarios.

Question 12

A common distractor is B, which fails because it misinterprets the end-of-day activity as front running a customer order, often misleading those unfamiliar with precise industry practices. To better identify such tactics, consider studying real-world cases and familiarizing yourself with regulatory guidelines. Practice distinguishing between legitimate trading strategies and manipulative actions by analyzing diverse scenarios.

Question 13

In the provided scenario, insider trading is demonstrated through the corporate officer tipping a friend about an upcoming earnings miss, with the friend trading and profiting before announcement. This highlights the breach of insider trading prohibitions under antifraud rules such as Rule 10b-5. The correct answer is A, as it accurately identifies the manipulation tactic used, aligning with industry definitions and regulatory standards. A common distractor is B, which fails because it misinterprets the violation as mutual fund discount rules rather than trading on nonpublic information, often misleading those unfamiliar with precise industry practices.

Question 16

The increased use of online forums and social media has made which of the following manipulative practices more prevalent and easier to execute?

  1. Backing away
  2. Pump and dump (correct answer)
  3. Freeriding
  4. Marking the close
Explanation: 'Pump and dump' schemes depend on the wide and rapid dissemination of misleading information to create artificial interest in a stock. Social media provides an ideal platform for manipulators to reach a large audience quickly, making this specific violation easier to perpetrate.

Question 17

The determination of whether trading activity in a customer's account is excessive is primarily based on the:

  1. total commission generated for the firm from the account.
  2. customer's investment objectives and financial situation. (correct answer)
  3. net profit or loss realized in the account over a one-year period.
  4. customer's explicit written approval for each trade.
Explanation: Whether trading is excessive (churning) is judged against the customer's specific profile, including their investment objectives, risk tolerance, and financial situation. A trading strategy that is suitable for a day trader would be excessive for a conservative, long-term investor. Profitability or customer approval does not excuse churning.

Question 18

A group of individuals coordinates to acquire a large position in a thinly traded stock, then promotes it on social media with exaggerated claims to attract buyers. Once the price increases, the original group sells its shares, causing the price to collapse. This prohibited practice is known as:

  1. front running.
  2. pump and dump. (correct answer)
  3. backing away.
  4. freeriding.
Explanation: This is a classic 'pump and dump' scheme. It involves artificially inflating (pumping) the price of a security through false and misleading positive statements in order to sell (dump) the cheaply purchased securities at a higher price. Front running is trading ahead of a known customer order. Backing away is a market maker's failure to honor a firm quote. Freeriding is selling a security before paying for its purchase.

Question 19

A trader places numerous small buy orders for a stock in the last few minutes of the trading day. The trader's goal is to cause the stock to close at a higher price, which would increase the value of a large options position they hold. This manipulative activity is best described as:

  1. marking the close. (correct answer)
  2. pegging.
  3. churning.
  4. front running.
Explanation: Marking the close is the practice of attempting to influence a security's closing price by executing a series of transactions at or near the close of trading. Pegging is the illegal act of preventing a stock's price from falling. Churning is excessive trading to generate commissions. Front running is trading ahead of a large customer order.

Question 20

A registered representative at a large broker-dealer receives a block order from a pension fund to buy 500,000 shares of ABC stock. Before executing the fund's order, the representative buys 500 shares of ABC for his own account. This prohibited practice is an example of:

  1. backing away.
  2. insider trading.
  3. freeriding.
  4. front running. (correct answer)
Explanation: Front running is the prohibited practice of a securities professional trading on their own account based on advance knowledge of a pending large customer order that is likely to affect the market price. While it involves non-public information, the specific violation of trading ahead of a client's block order is front running.
