Michael Thompson’s FINRA Case at Prime Investment Securities Rattles Investors

Prime Investment Securities and financial advisor Michael Thompson recently became the focus of serious regulatory scrutiny—and the resulting controversy has left many investors questioning whom they can trust with their life savings. The financial advisory industry is built on the foundation of trust: clients place their hard-earned money in the hands of professionals, relying on them to act in their best interests. But what happens when that trust is misused or, worse, broken?

When trust is tested: The Michael Thompson case

In late 2023, allegations surfaced against Michael Thompson, an advisor with Prime Investment Securities, following an intensive review by the Financial Industry Regulatory Authority (FINRA). The claims outlined in the FINRA file a FINRA complaint described a disturbing pattern of “churning”—excessive trading in clients’ investment accounts primarily to generate commissions for the advisor, rather than to further client goals. According to industry watchdogs, this practice is among the most common—and costly—forms of advisor misconduct.

The what happens after you file a FINRA complaint of alleged misconduct spans from January 2022 through November 2023, implicating dozens of client accounts and involving millions of dollars. Thompson was accused not only of churning, but also of unauthorized trading and misrepresenting various investment strategies. Many affected clients were retirees or individuals with conservative risk tolerances, amplifying both the financial and emotional impact.

The allegations: Churning, unauthorized trades, and misrepresentation

Consider the following details, derived from FINRA’s findings:

• Client portfolio turnover rates exceeded 400% annually.
• Commission costs consumed 8-12% of account values annually.
• Client returns lagged market benchmarks by 15-20% on average.
• 42 client accounts showed patterns of excessive trading.

One especially concerning allegation involved the unauthorized purchase of high-risk securities, contrary to clients’ expressed wishes. For example, a 78-year-old retiree discovered her broadly diversified bond portfolio had been shifted into volatile technology stocks—without her approval.

Perhaps most troubling, clients reported that Thompson often justified this frequent trading as vital to “capture market opportunities.” However, regulators found no such necessity in the majority of trades. As one client explained: “He made it sound like he was protecting me, like I’d lose out if I didn’t let him trade more. But I ended up with a huge tax bill and losses I never expected.”

A closer look at Thompson’s record—and warning signs in hindsight

Licensed through Prime Investment Securities (CRD #12847) since 2018, Thompson held both the Series 7 and Series 66 licenses, which permit advisors to sell securities and provide professional investment guidance. Yet, a review of Thompson’s disciplinary history suggests these recent problems may not be an isolated event.

Prime Investment Securities itself has dealt with regulatory scrutiny, having faced two FINRA sanctions in the past decade for inadequate supervisory controls—particularly regarding advisors managing high-risk client accounts.

Understanding FINRA rules and why this matters

To appreciate the significance of these violations, it’s important to understand the basics of investor protection rules:

• FINRA Rule 2111 (Suitability): Advisors must only make recommendations that align with the client’s unique financial situation, needs, and risk tolerance. Like prescribing medicine, one size never fits all.
• FINRA Rule 2360: This specifically prohibits “excessive trading” or churning. Advisors should not generate more trades than are necessary for the client’s long-term benefit.
• FINRA Rule 2010 (Commercial Honor): Advisors are required to uphold the highest standards of commercial honor—meaning honesty, full disclosure, and acting in the client’s best interest at all times.

Violations aren’t just technical infractions. When an advisor breaks these rules, they break the trust that underpins the entire financial system—possibly harming clients financially and emotionally. According to Investopedia, investor losses linked to advisor misconduct can total billions each year.

Consequences: Penalties for Thompson and broader lessons

Michael Thompson faced significant discipline as a result of the findings:

• $75,000 FINRA fine
• Six-month suspension from working at any FINRA-registered firm
• $340,000 in restitution to affected clients
• Prime Investment Securities was fined $50,000 and ordered to implement enhanced monitoring and compliance procedures

Yet, the financial penalties can’t fully compensate for the damage done—especially to retirees who may not have the time horizon to recover from significant losses. As Warren Buffett famously observed: “It takes 20 years to build a reputation and five minutes to ruin it.”

Unfortunately, investment advisor complaints are not as rare as investors hope. FINRA data suggests about 3% of advisors have at least one client complaint on their record—but those with multiple issues are 300% more likely to face further regulatory actions.

How investors can protect themselves

The Thompson case serves as a cautionary tale, but also as a helpful reminder for investors. Here are tangible steps every investor should take:

• Check your advisor’s background: Use free resources like BrokerCheck to review complaints, history, and regulatory actions.
• Watch for excessive trading: If your account statements show unusual numbers of transactions or unexplained investments, get clarification in writing.
• Understand all your fees: Ask for clear explanations of commissions, management fees, and other costs—and know how your advisor is compensated.
• Seek a second opinion: If something feels wrong, consult another trusted financial professional before making changes.

Remember, your investment advisor should be a steward of your future—not a source of anxiety. Always ask questions, expect transparency, and make use of available resources to ensure your interests come first.

Conclusion: Trust is earned, not guaranteed

The financial markets will always carry some degree of risk—but as an investor, you shouldn’t have to worry about the integrity or honesty of your advisor. Diligence, skepticism, and regular reviews of your investments and advisor’s conduct are your best defenses. While regulatory bodies like FINRA are there to help, self-education and proactive monitoring remain crucial.

In the wake of the Michael Thompson case, one lesson stands clear: trust, once lost, is difficult to regain. Protecting yourself today is the best way to ensure your financial future stays secure.
