Investors potentially experienced sales practice violations by securities broker John Michael McArthur [CRD: 4389397, St. Louis, Missouri], based on disclosures on Financial Industry Regulatory Authority (FINRA) BrokerCheck. Mr. McArthur has been registered with Krilogy since February 24, 2012, and with Saxony Securities Inc. since November 28, 2014. Readers should continue reviewing this information to find out more about a pending client dispute reported on his record.
Evidently, on April 7, 2026, a Krilogy client filed FINRA Arbitration No. 26-00778 about John McArthur. Mainly, the client alleged that McArthur recommended private securities that were not appropriate for the client's circumstances and also provided misleading information regarding certain aspects of those investments. Because of this, the client allegedly sustained damages involving private securities. As a result, the client requested $1,000,000 in compensation from Krilogy or McArthur. BrokerCheck indicates that this arbitration is pending a resolution.
Misrepresentation of private securities generally refers to a situation in which a securities broker or financial advisor provides inaccurate, incomplete, or misleading information about an investment that is not publicly traded. Investors may rely on information concerning risks, liquidity, valuation, business operations, fees, or potential returns when deciding whether to invest.
If important facts are misstated or omitted, investors may be unable to make fully informed investment decisions. Private securities often involve limited public reporting and may be more difficult for investors to independently evaluate. For this reason, accurate disclosures are important so investors can properly assess whether an investment aligns with their objectives, financial needs, and tolerance for risk.
