William David Miller, a former registered representative with Osaic Wealth Inc. and affiliated Osaic firms, has been suspended by the Financial Industry Regulatory Authority for failing to respond to information requests under Rule 8210. The suspension bars Miller from acting as a broker while FINRA’s inquiry remains open.
What happened
FINRA initiated an investigation into Miller’s conduct and requested documents and information pursuant to Rule 8210. When Miller failed to provide the requested materials, FINRA issued a suspension order effective in August 2026. Rule 8210 grants FINRA broad authority to compel testimony, documents, and information from registered persons and member firms.
The suspension is administrative in nature. It does not constitute a final determination of misconduct. However, it prevents Miller from associating with any FINRA-member firm until the matter is resolved or he complies with the information request.

Broker details and firm background
Osaic Wealth Inc. is a large independent broker-dealer network with thousands of registered representatives across the United States. Osaic FS Inc. operates as an affiliated broker-dealer under the same corporate umbrella. Woodbury Financial Services Inc., also an Osaic affiliate, provides brokerage and advisory services to retail investors.
Firms of this scale are expected to maintain supervisory systems that monitor representative conduct, review client communications, and flag potential violations. When a broker fails to respond to FINRA requests, it raises questions about both individual accountability and the firm’s oversight procedures.
What investors should know
Clients who worked with Miller at Osaic Wealth or its affiliates should review their account statements for unusual activity. Common concerns include unauthorized trading, excessive transactions, concentrated positions, or recommendations that do not match the investor’s stated risk tolerance.
Investors can verify Miller’s full regulatory history through FINRA’s BrokerCheck database. BrokerCheck provides disclosure counts, registration history, and any settled or pending customer complaints.
What affected investors can do now
- Request a complete copy of your account history from the firm
- Document all communications with the broker and any firm supervisors
- Review statements for unauthorized trades or unsuitable recommendations
- Consult a qualified securities attorney to assess whether arbitration is appropriate
- File a complaint with FINRA if you believe misconduct caused losses
Common mistakes victims make
Many investors delay action after learning a broker has been suspended. They assume the suspension means the problem is resolved. In reality, administrative suspensions often precede or run parallel to customer harm. Waiting too long can weaken an arbitration claim.
Some victims sign settlement releases without understanding the full extent of their losses. Releases may bar future claims even when additional damages surface later. Others fail to preserve emails, account screenshots, or notes from phone calls that could support a case.
Investors who believe they suffered losses related to this matter may wish to consult a qualified securities attorney to review their options.
Regulatory context and enforcement trends
FINRA has intensified its use of Rule 8210 in 2026. The rule serves as the enforcement backbone for the self-regulatory organization, compelling cooperation from brokers and firms under investigation. When representatives refuse to comply, FINRA’s default remedy is suspension followed by a bar if the non-compliance continues.
The increase in Rule 8210 suspensions reflects broader regulatory pressure on broker-dealers to improve supervisory controls and respond promptly to examiner requests. Investors benefit from this transparency because disciplinary records become visible through BrokerCheck.
