How Series 23 fits the stack

Series 23 is not an entry-level sales exam. It is a principal-control exam for candidates who already carry the sales-supervisor base and now need the broader broker-dealer, trading, and investment-banking or research supervision layer.

How to use the Series 23 simulator efficiently

  1. Start with general broker-dealer controls and trading supervision because they drive most of the top-off logic.
  2. Review every miss until you can explain what the principal should approve, document, escalate, or stop.
  3. Move into mixed sets once you can switch between customer, trading, and IB or research scenarios without losing the supervisory thread.
  4. Finish with timed runs so the 150-minute pace feels stable.

6 Series 23 sample questions with detailed explanations

Question 1

Topic: Function 1 — Supervision of Registration of the Broker-Dealer and Personnel Management Activities

A branch manager tells the principal that a newly hired representative will begin soliciting customers tomorrow, but the firm still has not resolved a material disclosure on the candidate’s Form U4 and the branch has not documented any heightened supervision plan.

What is the best principal response?

  • A. Allow the representative to begin work because the U4 can be updated after the first 30 days
  • B. Permit limited solicitation as long as a senior representative co-signs each order
  • C. Delay customer-facing activity until the registration issue is addressed and the supervision plan is documented
  • D. Let the branch decide because Form U4 items are an HR matter rather than a principal issue

Best answer: C

Explanation: Series 23 expects principal-level control discipline. When a registration issue is unresolved, the defensible response is to hold customer-facing activity until the registration status and supervisory conditions are clean. Co-signing orders does not cure an unresolved registration or documentation problem.


Question 2

Topic: Function 2 — Supervision of General Broker-Dealer Activities

A representative has been recommending a private real-estate note program to several long-time customers through an outside entity. The representative says it is unrelated to the firm because no firm email or firm stationery was used.

What is the strongest principal action?

  • A. Ignore the activity unless a written customer complaint is received
  • B. Treat the activity as a potential outside business and private securities transaction issue and escalate for review immediately
  • C. Approve the activity verbally as long as the representative adds a personal disclaimer
  • D. Reclassify the activity as education because the product is not a listed security

Best answer: B

Explanation: The supervisory issue is not whether the firm brand was used. It is whether the activity creates outside-business or private-securities-transaction risk that requires firm review, documentation, and likely restrictions. Series 23 rewards the answer that identifies the escalation and control duty early.


Question 3

Topic: Function 3 — Supervision of Retail and Institutional Customer-Related Activities

A static social-media graphic prepared by a registered representative says, “Our income strategy beat the market by 12% last year.” The post contains no discussion of risk, fees, or that the result came from a single model portfolio, and it went live before principal approval.

Which issue matters most?

  • A. Only the missing principal approval matters
  • B. Only the missing balanced disclosure matters
  • C. Both the content imbalance and the approval failure create supervisory problems
  • D. Neither issue matters if the underlying performance figure is accurate

Best answer: C

Explanation: This is a two-part supervision problem. The communication is unbalanced because it highlights performance without the necessary context, and it also failed the firm’s approval process by going live before principal review. Series 23 often tests whether the principal can identify both the content defect and the process defect.


Question 4

Topic: Function 4 — Supervision of Trading and Market Making Activities

A trading exception report shows repeated late close-outs and repeated manual overrides of a short-sale restriction by one desk. The desk head argues that the firm should address the reporting backlog first because the trades were profitable.

What is the best principal response?

  • A. Focus only on the late reports because profit eliminates the need to review the trading decisions
  • B. Review the restriction overrides, stop the pattern if needed, and treat the reporting failures as a related supervisory issue
  • C. Allow the desk to continue while operations prepares a month-end summary
  • D. Reassign the issue to retail supervision because short-sale rules are a customer-protection topic

Best answer: B

Explanation: Series 23 expects the principal to treat trading controls and reporting controls together. Profit does not excuse possible restricted activity or override abuse. The defensible response is to investigate the restriction breaches, restrict activity if needed, and remediate the reporting-control weakness at the same time.


Question 5

Topic: Function 5 — Supervision of Investment Banking and Research

An analyst is scheduled to speak publicly about an issuer that recently engaged the firm’s investment-banking department. The research file does not show the required conflict disclosure language for the appearance.

What should the principal do?

  • A. Approve the appearance because oral events are not treated like research communications
  • B. Require the proper conflict disclosure and document the approval before the appearance occurs
  • C. Let the speaker decide whether the missing disclosure is material
  • D. Cancel all research coverage of the issuer permanently

Best answer: B

Explanation: Public appearances create supervisory duties around required disclosures and approval discipline. The principal’s role is to make sure the appearance is supported by the required conflict disclosures and a documented approval workflow before it occurs.


Question 6

Topic: Function 2 — Supervision of General Broker-Dealer Activities

Senior management wants to take a large capital distribution from the broker-dealer after a profitable quarter. The FINOP warns that the withdrawal would materially tighten the firm’s excess net capital cushion.

What is the most defensible principal response?

  • A. Approve the withdrawal because profitability proves the firm can absorb it
  • B. Defer the withdrawal until the financial-responsibility impact and any required approvals or notices are reviewed
  • C. Move the withdrawal through the parent company so the principal does not need to review it
  • D. Approve the withdrawal if the branch managers agree to reduce expenses next month

Best answer: B

Explanation: Series 23 expects principals to treat capital withdrawals as financial-responsibility issues, not just treasury decisions. The correct response is to pause, review the impact on net capital and required controls, and then proceed only if the withdrawal is consistent with the firm’s regulatory obligations.
