The U.S. Securities and Exchange Commission’s lawsuit against one of the country’s largest electronic trading firms, claiming that it failed to safeguard a database that contained sensitive customer information, is a warning to other companies to prevent misuse of material nonpublic information, securities attorneys said this week.  

Last month, the SEC sued broker-dealer Virtu Americas LLC and parent company Virtu Financial Inc., alleging the firm made false and misleading statements regarding the safety of customers’ confidential trading data.
