Trade Shredding and Order Entry Practices

Firms that route orders have a responsibility not to manipulate the process for their own benefit. This section covers prohibited practices related to order splitting and IPO trading restrictions.

Trade Shredding (FINRA Rule 5290)

  • Trade shredding is the practice of splitting a single customer order into multiple smaller orders for execution, or splitting executions into multiple smaller reports, for the primary purpose of maximizing monetary or in-kind payments to the member
  • This is prohibited under FINRA Rule 5290
  • Applies when a firm routes orders in a way designed to capture maximum exchange rebates or other payments rather than to benefit the customer
  • Violations undermine best execution obligations

Example: A customer places a 10,000-share order. The firm breaks it into 100 separate 100-share orders to maximize per-order rebates from an exchange. This is trade shredding -- the splitting benefits the firm, not the customer.

Think of it this way: The firm is supposed to work for the customer, not game the system for its own rebate income. If the reason for splitting the order is to pad the firm's pockets rather than to get the customer a better fill, that is trade shredding.

Exam Tip: Gotchas

  • Trade shredding is about the firm's purpose, not the result. Splitting orders to maximize rebates is prohibited even if the customer's execution quality is not obviously harmed.
  • "Primary purpose" is the key phrase. If order splitting is done for a legitimate reason (e.g., to minimize market impact for the customer), it is not trade shredding.

IPO Trading Restrictions (FINRA Rule 6130)

  • Restricts trading in a new issue before it officially begins trading on its primary market
  • Designed to prevent manipulation of Initial Public Offering (IPO) pricing
  • Members may not execute transactions in a new issue until the security begins trading on its designated exchange

Exam Tip: Gotchas

  • IPO trading restrictions apply until the security officially begins trading on its primary market. The restriction is tied to the exchange's official start of trading, not the effective date of the registration statement.
