Series 23 — General Securities Principal Sales Supervisor Module Cheat Sheet

Use the tables for a quick pre-exam check. Expand a topic’s notes for explanations, examples, and additional distinctions.

Scope and study context

For Series 23 questions, think like a principal:

• Prevent violations through written supervisory procedures, training, registration controls, and preapproval where required.
• Detect problems through reviews, exception reports, surveillance, branch inspections, and complaint analysis.
• Escalate and document red flags. A correct answer often includes evidence of follow-up, not just “reviewed.”
• Separate sales supervision from broader principal supervision: trading, market making, investment banking, research, communications, financial responsibility, and firm-level controls may be tested.

Principal mindset: prevent customer harm, supervise registered persons, identify conflicts, document reviews, escalate red flags, and follow written supervisory procedures.

Supervisory Framework: High-Yield Map

Notes and examples

High-Yield Supervisory Framework

A principal is expected to know the firm’s business, assign supervision, monitor exceptions, and correct problems.

Supervisory Area	Principal Focus	Common Exam Trap
Written supervisory procedures	Procedures must match the firm’s actual business.	Generic WSPs are not enough if they do not address the activity.
Branch and OSJ supervision	Designated supervisors, inspections, escalation, exception review.	Delegating a task does not remove supervisory responsibility.
Registered representative activity	Sales practices, recommendations, outside activities, compensation conflicts.	Assuming a rep’s experience replaces supervisory review.
Customer accounts	KYC, approvals, updates, discretionary authority, fiduciary accounts.	Treating all accounts the same despite different authority or risk.
Communications	Fair, balanced, not misleading; correct approval/review process.	Calling a communication “educational” when it contains a recommendation or projection.
Trading and order handling	Best execution, order tickets, priority, manipulation, short-sale rules.	Ignoring trade blotter and exception report red flags.
Complaints and investigations	Escalate, preserve, investigate, report if required.	Informal settlement or failure to preserve written complaints.
AML and fraud	CIP, monitoring, suspicious activity escalation, privacy safeguards.	Treating AML as only an account-opening issue.

Core FINRA Supervision Rules and Concepts

Notes and examples

FINRA Supervision Rules to Recognize

You do not need to recite rule numbers for every question, but recognizing the rule family helps you choose the right action.

Topic	Core Idea
FINRA Rule 3110 supervision	Firms must establish and maintain a supervisory system and written procedures reasonably designed to achieve compliance.
Branch inspections	Offices and activities must be inspected according to the firm’s supervisory system and risk profile.
Annual compliance meeting	Registered persons must receive compliance training/meeting content under the firm’s process.
FINRA Rule 3120 supervisory controls	Firms test and verify supervisory procedures and prepare reports.
FINRA Rule 3130 certification	Senior management certification relates to supervisory processes and compliance systems.
Delegation	Tasks may be delegated, but the firm and responsible principals remain accountable for reasonable supervision.
Heightened supervision	Required when risk indicators justify closer monitoring, such as prior disciplinary history or repeated exceptions.

Common Supervision Traps

• “The rep is senior, so less review is needed.” Wrong. Experience may affect risk assessment, but it does not remove supervisory obligations.
• “No customer complained, so there is no issue.” Wrong. Exception reports, trade patterns, and communications can reveal violations before a complaint.
• “The branch manager approved it verbally.” Documentation matters.
• “The procedure exists, so the firm is protected.” Procedures must be implemented, tested, and followed.
• “The activity happened outside the firm, so the firm has no concern.” Outside business activities, private securities transactions, and communications away from firm systems can create major supervisory issues.

OSJ, Branch, and Office Classification

Registration, Forms, and Personnel Controls

Principal Approval and Review Matrix

Customer Account and Recommendation Rules

KYC, Suitability, and Reg BI

Notes and examples

Regulation Best Interest Obligations

Reg BI obligation	What it means in scenarios
Disclosure	Disclose capacity, material fees/costs, services, limitations, and conflicts.
Care	Understand risks, rewards, costs, and reasonably available alternatives; avoid excessive series of transactions.
Conflict of interest	Identify, disclose, mitigate, or eliminate conflicts as required. Sales contests based on specific securities over limited periods are high-risk.
Compliance	Maintain policies, procedures, training, and surveillance reasonably designed for Reg BI compliance.

Account Type Decision Points

Scenario	Correct supervisory concern
Retirement rollover recommendation	Treat as an account recommendation; compare costs, services, investment options, conflicts, and investor needs.
Senior investor adds new trusted contact	Trusted contact helps address suspected exploitation or diminished capacity; it does not give trading authority.
Customer grants POA to third party	Verify authority, monitor for abuse, and ensure records reflect authorized agent.
Customer wants aggressive trading in IRA	Customer desire does not override suitability/Reg BI care obligations.
Customer refuses financial information	Firm may limit recommendations or decline account features that require the information.
Customer gives verbal discretion	Not sufficient for discretionary account authority. Obtain required written authorization and approval.
Pattern day trading or active margin use	Confirm disclosures, margin suitability, equity requirements, and risk controls.

Suitability, KYC, and Regulation Best Interest

For Series 23, recommendations are central. The exam often asks whether the principal should approve, reject, escalate, or investigate a sales practice.

FINRA Suitability Concepts

Under FINRA suitability principles, a recommendation must be suitable based on the customer’s investment profile.

Suitability Type	Meaning
Reasonable-basis suitability	The firm/rep must understand the product or strategy and have a reasonable basis to recommend it to at least some investors.
Customer-specific suitability	The recommendation must fit the specific customer’s profile.
Quantitative suitability	Even individually suitable trades can be excessive when viewed in the account context.

Regulation Best Interest Review Points

For retail recommendations, Regulation Best Interest adds a best-interest framework. In exam terms, focus on:

Obligation	Practical Review Question
Disclosure	Were material facts about the relationship, fees, capacity, and conflicts disclosed?
Care	Did the recommendation consider costs, risks, rewards, and reasonably available alternatives?
Conflict of interest	Were conflicts identified and addressed, not merely ignored?
Compliance	Does the firm have policies designed to achieve compliance?

Recommendation Traps

• Unsolicited order vs. recommendation: An unsolicited order should be marked correctly, but if the rep influenced the customer, it may still be a recommendation.
• High commission product: Not automatically prohibited, but the principal must evaluate costs, alternatives, suitability, and conflicts.
• Switching products: Switching mutual funds, annuities, or complex products requires analysis of costs, benefits, surrender charges, tax consequences, and investment purpose.
• Concentration: A product may be suitable in small size but unsuitable if it creates excessive concentration.
• Institutional accounts: Institutional suitability analysis considers the customer’s capability to evaluate risk independently, but the firm still must supervise recommendations.

AML, Privacy, and Red Flags

Communications Cheat Sheet

FINRA Communication Categories

Notes and examples

Content Standards

Rule of thumb	Example of compliant approach	Problem answer
Fair and balanced	Benefits and risks appear together and with similar prominence.	Prominent yield claim with hidden risk footnote.
No exaggerated claims	“May provide income, subject to credit and market risk.”	“Safe income with no downside.”
No misleading performance	Include material assumptions, period, fees, and limitations.	Cherry-picked performance period.
No unwarranted projections	Use only permitted illustrations with required basis and disclosures.	Predicting stock price or fund return.
Comparisons must be valid	Compare similar products using disclosed assumptions.	Comparing taxable and tax-exempt yields without tax basis.
Testimonials/endorsements	Must meet applicable disclosure and compensation rules.	Paid influencer post without disclosure.

Digital Communication Traps

Situation	Exam treatment
Static webpage/profile describing services	Usually treated like retail communication; principal approval and records matter.
Interactive social media forum	Supervision, training, surveillance, and recordkeeping still apply.
Rep uses personal texting for business	Business communication must be captured, supervised, and retained if permitted at all.
Hyperlink to third-party content	Firm may adopt or become entangled with content depending on control and context.
Seminar invitation	Review both invitation and script/slides; audience and product claims matter.

Communications With the Public

FINRA communications rules are heavily tested because they combine classification, approval, content standards, and recordkeeping.

Communication Categories

Category	General Meaning	Supervisory Point
Retail communication	Written or electronic communication made available to more than 25 retail investors within a 30-calendar-day period.	Generally requires principal approval before use, unless an exception applies.
Correspondence	Written or electronic communication to 25 or fewer retail investors within a 30-calendar-day period.	Subject to supervision and review under firm procedures.
Institutional communication	Communication only to institutional investors.	Subject to review/supervision; do not let it reach retail investors without proper treatment.
Public appearance	Seminars, interviews, forums, broadcasts, unscripted public remarks.	Must be fair and balanced; may trigger filing/disclosure issues depending on content.
Internal communication	Within the firm.	Still subject to supervision if it affects sales practices or compliance.

Content Standards

Communications must be:

• Fair and balanced.
• Not false, exaggerated, promissory, or misleading.
• Clear about risks as well as benefits.
• Consistent with prospectuses, offering documents, and product terms.
• Careful with projections, performance, testimonials, rankings, and comparisons.
• Clear that FINRA review or filing does not equal FINRA approval.

Communications Traps

Scenario	Better Exam Response
Rep posts product performance on social media.	Determine whether it is static/retail communication, review content, preserve records, and supervise interactive activity.
Seminar slide deck includes “safe income” language for a complex product.	Reject or revise; language is misleading if risk exists.
Institutional-only piece is forwarded to retail customers.	Treat as retail communication and address approval/content issues.
Communication shows benefits but hides liquidity limits.	Not fair and balanced.
Rep uses personal email/text to discuss securities business.	Escalate; firm must supervise and preserve business communications.

Sales Practice and Conduct Controls

Product Supervision Snapshot

Investment Banking and New Issue Reference

Offering Types

Notes and examples

Registered Offering Stages

Stage	Permitted/forbidden concept	Exam trap
Pre-filing	Avoid gun-jumping; offers generally restricted before filing	Conditioning the market with promotional material.
Waiting/cooling-off	Indications of interest and preliminary prospectus activity may be allowed; no final sales before effectiveness	Taking customer money as if sale is final.
Effective/post-effective	Sales with required prospectus delivery and confirmations	Omitting final prospectus or material changes.

IPO and New Issue Controls

Topic	Key rule logic
Restricted persons	FINRA new issue rules restrict allocations to broker-dealer personnel and other restricted persons unless an exemption applies.
Account representations	Firm must obtain and maintain required eligibility representations for new issue accounts.
Spinning	Allocating IPO shares to executives/directors to win investment banking business is prohibited.
Quid pro quo allocations	Allocations tied to excessive compensation or future business are prohibited.
Flipping and penalty bids	Must be handled under syndicate rules and disclosed where required.
Laddering	Requiring aftermarket purchases as condition of IPO allocation is prohibited.
Underwriting compensation	Must be fair, reasonable, disclosed, and reviewed under applicable corporate financing rules.

New Issues, IPOs, and Conflicts

High-yield principles:

• New issue allocations must not be used as compensation for investment banking business.
• Restricted persons generally cannot receive certain new issues unless an exemption applies.
• Firms must obtain and rely on appropriate customer representations, but must also supervise for red flags.
• Allocation practices should be fair, documented, and consistent with firm procedures.
• Spinning, quid pro quo allocations, and favoritism tied to business generation are major red flags.

IPO Trap Examples

Fact Pattern	Red Flag
Executive of an investment banking client receives hot IPO shares.	Possible spinning/conflict issue.
Rep allocates IPO shares to personal friends first.	Fair allocation and conflict concern.
Account ownership is through an entity.	Look through beneficial ownership and restricted-person status.
Customer flips shares repeatedly despite firm policy.	Review flipping policy, allocation suitability, and account behavior.

Regulation M, Research, and Information Barriers

Trading, Market Making, and Order Handling

Notes and examples

Manipulation Red Flags

Red flag	Why it matters
Wash trades or matched orders	Creates false appearance of activity.
Marking the close/open	Attempts to influence closing/opening price.
Layering/spoofing	Non-bona fide orders used to move market.
Parking stock	Hiding ownership or control.
Prearranged trades	May evade auction/market rules or create artificial prices.
Rumor spreading	Fraud/manipulation risk, especially around offerings or research.
Pump-and-dump pattern	Promotional activity followed by insider or customer liquidation.
Excessive cancellations	Can indicate spoofing or manipulative order entry.

Trading, Order Handling, and Market Conduct

Trading questions often test whether the principal recognizes unfair order handling, manipulation, or missing records.

Area	Key Review Point
Best execution	Firm must use reasonable diligence to obtain favorable terms for customer orders.
Order tickets	Terms, time, account, solicited/unsolicited status, buy/sell, quantity, price, and capacity must be recorded correctly.
Customer priority	Customer orders generally receive priority over firm or associated-person interest.
Trade corrections	Frequent cancels/corrections can signal errors, manipulation, or unauthorized trading.
Marking orders	Long, short, and short-exempt markings must be accurate.
Short sales	Locate, marking, and close-out requirements are core supervisory concerns.
Front-running / trading ahead	Trading for firm or personal accounts before customer orders is a serious violation.
Manipulation	Wash trades, matched orders, marking the close, pump-and-dump activity, and rumor spreading are red flags.
Trade reporting / audit trail	Required order and trade data must be complete and timely under applicable systems.

Margin Cheat Sheet

Margin questions may appear as supervision or account-risk scenarios. Know the basic equity relationships:

\[ \text{Long Account Equity} = \text{Long Market Value} - \text{Debit Balance} \]\[ \text{Short Account Equity} = \text{Credit Balance} - \text{Short Market Value} \]

Principal review focuses on:

• Whether the account was approved for margin.
• Whether the customer understands leverage and potential losses.
• Whether margin calls, extensions, liquidations, and restrictions are handled properly.
• Whether recommendations create unsuitable leverage or concentration.
• Whether day trading or active trading patterns create additional risk.

Trade Reporting, Confirmations, and Records

Financial Responsibility and Operations

Calculation and Formula Sheet

Use formulas to support supervisory judgment. The exam may test whether a principal recognizes an account problem, unfair charge, margin deficiency, or yield misrepresentation.

Margin Basics

\[ \text{Long account equity} = \text{long market value} - \text{debit balance} \]\[ \text{Short account equity} = \text{credit balance} - \text{short market value} \]\[ \text{Reg T initial requirement for a long stock purchase} = 50\% \times \text{purchase price} \]

Markup, Markdown, and Yield

\[ \text{Markup percentage} = \frac{\text{customer price} - \text{prevailing market price}} {\text{prevailing market price}} \times 100 \]\[ \text{Markdown percentage} = \frac{\text{prevailing market price} - \text{customer price}} {\text{prevailing market price}} \times 100 \]\[ \text{Current yield} = \frac{\text{annual income}} {\text{market price}} \]

Common Series 23 Scenario Traps

Final Cram Checklist

Before exam day, be able to answer these quickly:

1. Who must approve or review the activity?
2. Is approval required before use, before trade, or through post-use surveillance?
3. Is the communication retail, correspondence, or institutional?
4. Is the interaction a recommendation under Reg BI or FINRA suitability?
5. What customer facts are missing?
6. Is the customer retail, institutional, accredited, senior, or entity-based?
7. Is the rep properly registered for the activity?
8. Is the office correctly classified and inspected?
9. Does the firm have WSPs that match the activity?
10. Did an exception report require follow-up?
11. Is there a conflict of interest, compensation conflict, or sales contest issue?
12. Is there MNPI or an information-barrier concern?
13. Does the trade raise best execution, limit order, Manning, or short sale concerns?
14. Is a trade report, confirmation, or order record inaccurate?
15. Does the offering involve restricted persons, spinning, Reg M, or underwriting compensation?
16. Is a private placement being sold with adequate due diligence?
17. Is a product complex, illiquid, leveraged, callable, or fee-heavy?
18. Are customer assets protected and properly segregated?
19. Does AML or sanctions review need escalation?
20. Was the supervisor’s decision documented?

The Series 23 Supervisory Mindset

Series 23 questions often test what a principal or sales supervisor should do before, during, or after a customer-facing activity. The best answer usually combines three ideas:

1. Reasonable supervision — not perfection, but a system reasonably designed to detect and prevent violations.
2. Documented process — if the review, approval, exception, or escalation is not documented, it is hard to prove.
3. Customer protection — when in doubt, choose the answer that protects the customer, preserves records, and escalates appropriately.

Fast Decision Questions

Ask these on nearly every scenario:

Principal Review Workflow

    flowchart TD
	    A[Customer, rep, communication, or trade activity] --> B{Is it customer-facing?}
	    B -- Yes --> C{Recommendation or sales communication?}
	    B -- No --> D{Internal control, record, or personnel issue?}
	
	    C -- Recommendation --> E[Apply KYC, suitability, Reg BI, conflicts, product risk]
	    C -- Communication --> F[Classify communication and apply approval/review rules]
	
	    E --> G{Red flag or exception?}
	    F --> G
	    D --> G
	
	    G -- No --> H[Document normal review under WSPs]
	    G -- Yes --> I[Escalate, restrict activity if needed, investigate, document]
	
	    I --> J{Customer harm, complaint, AML, fraud, or reporting issue?}
	    J -- Yes --> K[Follow firm escalation and regulatory reporting process]
	    J -- No --> L[Correct, supervise, train, and monitor]

Account Opening and Customer Information

Account questions usually test whether the firm obtained enough information, whether the correct person has authority, and whether the principal reviewed the account appropriately.

Notes and examples

Account Type Traps

Account Type	Exam Trap
Joint account	Know whether ownership is tenants in common or joint tenants with right of survivorship. Do not assume one joint owner may remove the other’s rights.
Trust account	The trustee’s authority comes from the trust document. Suitability considers the trust’s purpose and beneficiaries.
Corporate account	Look for corporate resolutions and authorized traders.
Custodial account	The minor is the beneficial owner; the custodian controls the account until the applicable termination event.
Discretionary account	Requires written customer authorization and firm acceptance. Time-and-price discretion is much narrower than full discretion.
Fiduciary account	The fiduciary’s duty and authority must be respected; personal benefit to the fiduciary is a red flag.
Margin account	Requires margin agreement/approval and ongoing monitoring for risk, calls, extensions, and concentration.

Product and Sales Practice Review

The Series 23 exam may describe a product and ask what a principal should question. Do not focus only on whether the product is “allowed.” Focus on customer fit, risk disclosure, conflicts, documentation, and approval process.

Research, Investment Banking, and Information Barriers

Series 23 candidates should recognize conflicts between research, investment banking, trading, and sales.

MNPI and Insider Trading Traps

• Possession of MNPI creates a duty to restrict trading and sharing.
• Rumors should not be spread to generate trades.
• Tender offers, mergers, earnings, and offerings are common MNPI contexts.
• Information barriers are not just paperwork; they must actually control access and trading.

Customer Complaints and Escalation

A customer complaint is not a routine service issue once it alleges misconduct, loss, unauthorized activity, misrepresentation, theft, or sales-practice abuse.

Complaint Review Checklist

Notes and examples

Complaint Traps

• A rep cannot personally settle a complaint away from the firm.
• Do not alter account records or correspondence after receiving a complaint.
• Oral complaints may still require escalation under firm policy, even when written complaints have specific recordkeeping significance.
• “The customer is confused” is not a sufficient investigation.
• Repeated small complaints may show a larger supervisory pattern.

AML, Fraud, Privacy, and Financial Exploitation

AML and fraud questions usually test escalation, monitoring, and documentation.

Notes and examples

Senior Investor Traps

Trap	Correct Concept
Trusted contact is treated as authorized trader.	A trusted contact is for contact/escalation, not trading authority.
Rep follows suspicious withdrawal instructions without review.	Escalate possible exploitation or diminished capacity concerns.
Customer’s family member pressures the rep.	Verify authority and protect customer confidentiality.
Firm ignores sudden liquidation inconsistent with profile.	Review, document, and escalate red flags.

Outside Activities and Conflicts

FINRA frequently tests whether a principal distinguishes ordinary outside work from securities activity.

Notes and examples

OBA vs. Private Securities Transaction

If the activity is…	Think…
Non-securities outside work, paid consulting, board service, side business	Outside business activity review.
Selling promissory notes, private funds, crypto-related securities, limited partnership interests, or other securities away from the firm	Private securities transaction / selling away issue.
Receiving compensation for referring securities investors	Possible securities activity and conflict issue.
Approved compensated private securities transaction	Firm may need to record and supervise it as firm business.

Books, Records, and Documentation

The exam often rewards the answer that preserves evidence and follows the recordkeeping process.

Notes and examples

Documentation Traps

• “Reviewed” should be evidenced, not assumed.
• Corrections should be transparent, dated, and explained.
• Personal devices and off-channel communications create preservation and supervision problems.
• Exception reports are not useful if no one investigates the exceptions.
• Records must be retained in the required format and for the required period under applicable rules and firm procedures.

Branch Office and Personnel Supervision

Registered Person Oversight

Principals supervise people as well as accounts and transactions.

Branch Inspection Red Flags

• High concentration of complaints.
• Large number of trade corrections.
• Unapproved advertising or social media.
• Use of personal email or messaging apps.
• Unusually high commissions or product concentration.
• Frequent mutual fund or annuity switches.
• Outside business activity rumors.
• Cashiering irregularities or customer fund movement concerns.
• Unregistered assistants taking orders or making recommendations.

Common “Best Answer” Patterns

Quick Tables for Final Review

Prior Approval vs. Post-Use Review

Notes and examples

Customer Protection Red Flags

Red Flag	Likely Action
Unauthorized trading allegation	Escalate complaint, review orders/communications, preserve records.
Sudden large withdrawal by elderly customer	Review for exploitation, contact trusted contact if appropriate, escalate.
High turnover and commissions	Quantitative suitability review.
Rep guarantees returns	Stop communication, investigate, discipline/train if needed.
Customer does not understand complex product	Do not approve recommendation without adequate basis and disclosure.
Suspicious wire to unrelated third party	AML/fraud escalation.
Personal email used for securities instructions	Escalate off-channel communication issue.
Repeated trade corrections	Investigate potential unauthorized trading or operational issue.

Product Risk Shortcuts

Product Feature	Supervisory Concern
Illiquid	Customer liquidity needs and time horizon.
Leveraged	Losses amplified; not ordinary buy-and-hold risk.
Complex payoff	Customer understanding and disclosure quality.
High commission	Conflict, cost comparison, reasonable alternatives.
Surrender charge	Replacement/switching analysis.
Tax-sensitive	Customer tax status and after-tax impact.
Concentrated	Portfolio-level suitability, not just trade-level suitability.
Issuer credit risk	Especially relevant for structured products and debt-like instruments.

Practice Strategy for Series 23

Use this Cheat Sheet before practice, then let the question bank expose weak areas.

Recommended Drill Sequence

1. Supervision and WSPs
   • Focus on principal responsibility, delegation, escalation, and documentation.
2. Accounts and suitability
   • Drill KYC, discretionary accounts, fiduciary accounts, Reg BI, and excessive trading.
3. Communications
   • Drill classification, approval, misleading content, social media, and public appearances.
4. Products and sales practices
   • Drill mutual funds, variable annuities, private placements, structured products, IPOs, and complex products.
5. Trading and market conduct
   • Drill best execution, order handling, short sales, manipulation, and trade reviews.
6. Complaints, AML, and records
   • Drill escalation, preservation, suspicious activity, privacy, and senior investor protection.

Build an Error Log

For every missed original practice question, classify the miss:

Final Exam-Day Reminders

• Think like a principal, not a salesperson.
• Protect the customer first, then document and escalate.
• Do not assume disclosure cures an unsuitable or conflicted recommendation.
• Do not ignore off-channel communications, outside activity, or repeated exceptions.
• Retail communications must be fair, balanced, and properly approved/reviewed.
• Suitability and Reg BI analysis depends on the full customer profile.
• Written complaints, AML red flags, fraud concerns, and senior exploitation concerns require escalation.
• Delegation does not eliminate supervisory responsibility.
• If the answer choice says “no action is required,” be skeptical when red flags are present.
