According to FINRA, Miguel Angel Murillo was fined $5,000 and suspended for eight months for excessively and unsuitably trading customer accounts. Each customer relied on Murillo's advice and accepted his recommendations. Those transactions collectively caused customers to pay $101,508.10 in commissions and other charges. Murillo's firm agreed to pay restitution equal to the commissions and trading costs as a result of his conduct. Excessive trading enriches brokers through commissions while harming customers through unnecessary costs that erode investment returns. Investors should monitor trading frequency and costs, and question activity that seems excessive relative to their investment objectives.
