Problem
As the industry shifts to digital documents and cloud storage, broker-dealers face challenges meeting 17a-4’s specific WORM (Write Once, Read Many) requirements. Common problems include:
Lack of Immutability: Traditional cloud storage solutions may allow accidental overwrites or edits.
Disorganized Archives: Files scattered across local drives, email attachments, or multiple vendors can make it difficult to produce records within specified timeframes.
Retrievability & Indexing Gaps: SEC rules require that records be readily searchable and easily retrievable. Many broker-dealers rely on outdated, inefficient archives that complicate compliance audits.
Costly Fines: Even minor infractions—like failing to properly index or maintain files on a non-erasable format—can lead to enforcement actions and significant penalties.
WHO: Every broker-dealer governed by SEC Rule 17a-4 must ensure the proper retention and safekeeping of certain records in a non-rewriteable, non-erasable (WORM) format. This includes client statements, trade confirmations, account records, and other critical documents. While many large broker-dealers have their own archival systems, small- and mid-sized firms often rely on third-party or cloud-based storage. Regardless of the storage solution, Rule 17a-4 mandates strict requirements around immutability, retrievability, and auditability of archived records.
Firms Fined for Inadequate Influencer Marketing Supervision

In March 2024, M1 Finance was fined $850,000 for social media posts made by influencers on the firm’s behalf that were not fair or balanced, or contained exaggerated, unwarranted, promissory or misleading claims. This was first social media influencer-related FINRA Enforcement disciplinary action. As M1 Finance did not review or approve the content in its influencers’ posts prior to use or retain those communications, the findings also stated that M1 Finance failed to have a reasonable system…for supervising the communications that the firm’s influencers made on its behalf.

In April 2024, Cobra Trading, Inc. was fined $200,000 for findings that it paid influencers for promotional communications on social media platforms while the communications were not fair and balanced or made claims that were promissory. Cobra Trading did not review or approve influencers’ videos prior to their publication and did not maintain records of influencers’ videos or the dates they were used, but also failed to establish and maintain a supervisory system…to supervise its influencers’ retail communications.

In June 2024, TradeZero America was fined $250,000 for findings that its influencer communications were not fair and balanced and included exaggerated and promissory statements. Amongst the findings that the broker-dealer did not reasonably supervise its retail communications posted by influencers for compliance with FINRA Rule 2210(d)(1), the firm did not establish or maintain a supervisory system…to preserve records of influencers’ videos or their dates of use.
