Matt Gimmelli Faces $1 Million Complaint for Alleged Investment Mismanagement

Scottsdale, Arizona financial advisor Matt Gimmelli recently received an investor complaint alleging that his advice resulted in significant financial losses. According to Financial Industry Regulatory Authority records, he is registered as a broker and an investment advisor with Morgan Stanley.

The complaint, filed in March 2026, alleges that Mr. Gimmelli violated Regulation Best Interest and misrepresented fees and costs associated with the customer's accounts. The pending complaint seeks damages of $1.035 million.

Regulation Best Interest requires advisors like Mr. Gimmelli to recommend investments and strategies that are in their clients' best interests. This rule is similar to FINRA's suitability rule, which requires brokers to recommend investments that align with their customers' background and objectives.
