A principal responsible for trading supervision discovers a pattern of repeated Regulation SHO 'locate' violations by an experienced registered representative. The representative frequently enters short sale orders without proper documentation of a borrow or reasonable belief of ability to borrow. The firm's existing Written Supervisory Procedures (WSPs) clearly outline the 'locate' requirements. What is the most appropriate initial action for the principal to take, consistent with FINRA Rule 3110 and 3120?

Worked Practitioner Scenario

Practitioner Application: Supervisory Controls for Regulation SHO Locate Requirements and Exceptions

A principal at a broker-dealer receives an urgent request from a hedge fund client to execute a significant short sale in a thinly traded stock. The firm's automated locate system shows no available shares. The trader, under pressure, suggests using a previous, unrelated locate from three days ago for a different client, arguing that the shares are 'likely still available.' The principal must decide whether to approve the short sale, knowing the firm's supervisory procedures require a current and valid locate. What is the principal's obligation here, and what are the potential regulatory consequences of approving the trade without a fresh locate?

  1. Regulation SHO, specifically Rule 203(b)(1), mandates that a broker-dealer must have reasonable grounds to believe that the security can be borrowed and delivered on settlement date before executing a short sale. This is known as the locate requirement. The purpose is to prevent 'naked' short selling, which can lead to settlement failures and market manipulation. Firms must establish and maintain supervisory controls to ensure compliance with this rule.
  2. Reasonable Grounds for Belief To satisfy the locate requirement, a broker-dealer must have a current and valid basis for believing the shares can be borrowed. This is not merely an informal inquiry but requires documented evidence. Acceptable methods for obtaining a locate include: Bona fide loan of securities: The firm has entered into an agreement to borrow the securities, or has reasonable assurance that it can borrow them. Arrangement to borrow: The firm has an arrangement with a customer or another broker-dealer to borrow the securities. Easy to borrow list: The security appears on an 'easy to borrow' list, provided the list is updated daily and reflects actual availability. Proprietary inventory: The firm itself holds the securities in its own inventory and intends to deliver them.
Supervisory Review and Recordkeeping Broker-dealers must implement Written Supervisory Procedures (WSPs) under FINRA Rule 3110 to ensure proper compliance with Regulation SHO. These WSPs should detail the process for obtaining, documenting, and verifying locates. Principals are responsible for ensuring that these procedures are followed and that adequate records are maintained for three years, the first two in an easily accessible place, as per SEC Rule 17a-4. This includes records of all locates, their sources, and the associated short sale orders.
Exam Watchouts & Statutory Boundaries

Common FINRA Series 24 Distractors on FINRA Rule 3110

  • 1Test questions often focus on the nuances of what constitutes a valid locate and the limitations of exceptions.
  • 2⚠️ Exam trap: Assuming an 'easy to borrow' list is always sufficient. The trap is that the list must be updated daily and reflect current availability. An outdated list is not a valid locate.
  • 3⚠️ Exam trap: Confusing the locate requirement with the close-out requirement. While related, the locate requirement is pre-trade (before executing the short sale), while the close-out requirement (Rule 204) is post-trade and applies to failures-to-deliver.
  • 4⚠️ Exam trap: Overlooking the recordkeeping requirements. Principals must ensure that all locates and related documentation are maintained for the specified period (three years, first two easily accessible).
  • 5Locate Requirement: Before a short sale, a broker-dealer must have reasonable grounds to believe the security can be borrowed and delivered.
