Investment advisers sometimes place a single large securities order for multiple clients and then allocate portions of that trade among the individual accounts they manage. A newly approved FINRA rule change is intended to make that behind-the-scenes process more efficient without eliminating safeguards designed to prevent advisers from deciding who receives favorable trades after seeing how those trades performed.
The Securities and Exchange Commission approved the change to FINRA Rule 4515.01 on September 2, 2026. The approval was published in the Federal Register on September 8. Although the rule is primarily operational and will be most noticeable to broker-dealers and investment advisers, it involves a process that ultimately determines how trades are assigned to individual investors’ accounts.
What Is a Bulk Investment Adviser Order?
An investment adviser managing numerous client portfolios may determine that the same stock, bond or other security should be bought or sold for multiple accounts. Rather than sending a completely separate market order for every client, the adviser can place a larger—or “bulk”—order covering multiple accounts and subsequently provide instructions allocating portions of that trade among the participating clients.
FINRA Rule 4515 addresses recordkeeping and account-designation requirements associated with that process. The rule includes safeguards intended to prevent allocation practices that could disadvantage certain clients.
For investors, one particularly important principle is that an adviser shouldn’t be able to wait and see whether a trade rises or falls and then give the more favorable result to preferred accounts.
FINRA Is Removing a Trade-Date Deadline
Under the previous version of FINRA Rule 4515.01, broker-dealers could use an exception from certain principal-approval requirements for investment adviser bulk orders when allocation instructions were received no later than the end of the trade date. The newly approved amendment eliminates that timing requirement.
The exception will instead apply to allocations of qualifying investment adviser bulk orders regardless of when the broker-dealer receives the allocation instructions.
FINRA argued that the previous deadline could create unnecessary operational problems, particularly when investment advisers were unable to deliver final allocations before the end of the trading day. The SEC agreed that eliminating the timing condition could reduce operational burdens, help firms process allocations more efficiently and reduce potential settlement risks.
The Change Doesn’t Let Advisers Assign Winners After the Fact
Removing the trade-date condition doesn’t eliminate the investor-protection requirements surrounding bulk allocations. FINRA members still cannot knowingly facilitate an allocation that violates the investment adviser’s stated intent at the time the order was executed or breaches the adviser’s fiduciary duty to participating accounts. That includes allocations based on how a trade performs between execution and the time the accounts are assigned.
Imagine, for example, that an adviser places a bulk purchase for several client accounts and the security’s price jumps shortly afterward. The rule change isn’t intended to allow the adviser to wait for that price movement and then direct more of the profitable trade to favored clients.
The SEC specifically cited the continued existence of those protections when approving the amendment.
Why FINRA Wanted the Rule Changed
FINRA filed the proposed amendment with the SEC on July 9, 2026, and the Commission published notice of the proposal later that month. According to the regulatory filing, changes in trade settlement and industry operations can make timely and accurate allocation processing increasingly important. Requiring principal approval simply because instructions arrived after the end of the trade date could introduce additional steps and potentially delay processing.
The amendment also applies to qualifying delivery-versus-payment and receive-versus-payment arrangements and to prime brokers receiving allocation instructions directly from investment advisers. The SEC received no public comments on the proposed change before approving it.
The Commission concluded that the amendment was consistent with requirements of the Securities Exchange Act governing FINRA rules, including provisions intended to protect investors, prevent fraudulent and manipulative practices and remove unnecessary impediments to efficient markets.
What Does This Mean for Individual Investors?
Most people with brokerage or professionally managed investment accounts won’t need to take any action because of the rule change. The amendment primarily changes an operational requirement for FINRA-member broker-dealers handling bulk orders placed by investment advisers. It doesn’t change an investor’s account ownership, give advisers permission to ignore their fiduciary duties or eliminate protections against allocating trades based on their subsequent performance.
Individual investors may never see the allocation process at all, even though it can determine how a larger transaction ultimately appears in their accounts. For clients of investment advisers, the broader principle remains important: advisers handling aggregated trades should have policies designed to allocate investments fairly rather than favoring particular clients after the outcome of a trade becomes known.
The SEC’s September approval changes when a broker-dealer must obtain principal approval in the allocation process, but it does not remove that fundamental investor-protection principle.
