A Darien man who worked as an investment adviser without the proper registration has been barred from the securities industry for 10 years, according to a U.S. Securities and Exchange Commission order issued Wednesday.

John Vincent Greco was president of Darien-based DFS Capital Management from August 2009 to December 2011, but was not registered under the Connecticut Uniform Securities Act.

The former Stamford resident, however, continued to transact business through DFS as an unregistered investment adviser, according to the commission's order.

Attempts to reach Greco on Wednesday were unsuccessful.

Greco also made misrepresentations and omissions regarding DFS Fund to at least two investors, and two investors in DFS Fund each incurred more than $100,000 in trading losses.

The order stated Greco made a false or misleading statement to the Connecticut Department of Banking during its investigation.

In May 2013, Greco consented to an order issued by the Connecticut Department of Banking, which banned him from the securities and investment adviser business in the state for a decade.

Two months later, he was found in violation of the order for failing to repay one investor.

"As a result, the allegations were deemed admitted by Greco," the order states.

He was therefore barred from association with "any broker, dealer, investment adviser, municipal securities dealer, municipal advisor, transfer agent, or nationally recognized statistical rating organization with the right to apply for reentry after ten years to the appropriate self-regulatory organization, or if there is none, to the commission."
