The SEC has barred Michael Siva, who had worked as an advisor at Morgan Stanley.

Siva worked at the wirehouse for 22 years, from 1996 to 2018. The bar comes after Siva was convicted for insider trading.

Exactly one year prior to the SEC ruling, Siva pleaded guilty in federal court to conspiracy to commit securities fraud, admitting that he had received nonpublic information about potential M&A transactions and then used the information to buy stocks for himself and his clients.

A Morgan Stanley spokesperson declined to comment.

A 57-year old resident of West Orange, N.J., Siva is no longer registered with Finra.

Siva apparently generated more than $5 million in revenues from the insider trading, which was based on tips from a Bank of America consultant, who was dating his daughter, according to court filings and the SEC's order.

Siva was one of seven people charged in 2017 with trading on information about pending mergers.

Morgan Stanley discharged Siva in August 2017 following charges against him from the SEC and the Department of Justice, according to his BrokerCheck profile.

In February 2019, Siva was sentenced to 18 months in prison.
