New York-based Siebert Financial Corp. announced Thursday it acquired the discount brokerage accounts and certain assets of Your Discount Broker Inc. of Boca Raton.

Terms of the deal were not disclosed.

The Your Discount Broker name will be retained as a division of Muriel Siebert & Co., and its Aventura and Boca Raton branches will become Siebert branches. Michael Silverstein, a principal of Your Discount Broker, was named senior vice president, Florida Region, of Muriel Siebert & Co.

This is the third Florida acquisition in less than a year for Siebert Financial, holding company for Muriel Siebert & Co., discount brokers that earlier bought the retail discount brokerage accounts of TradeStation Securities Inc., Boca Raton, and the Boca Raton accounts of State Discount Broker.

“We know the area,” said the firm’s founder, Muriel Siebert. Siebert has offices in Boca Raton, Palm Beach, Surfside and Naples as well as nationwide.

Siebert said she is always looking for an opportunity to grow, especially when she “sees a company similar to ours and there is a synergy and we can offer our clients more products.”

Siebert said her company’s services draw a well-educated hands-on investor. “They are professional, many are early retirees: they are active and like to manage their own money,” Siebert said at the Boca Raton Resort & Club, where about 40 luncheon guests gathered to celebrate the announcement.

M.J. Mike Arts, Greater Boca Raton Chamber of Commerce president and luncheon guest, said, “Now, with the Siebert name attached to the brokerage, it gives us a national and international presence. “

Muriel Siebert herself has made national news: as the first woman to purchase a seat on the New York Stock Exchange in the 1967. In 1975, Siebert’s firm was one of the first to adopt a discounted commission schedule.

Last year, she published Changing the Rules: Adventures of a Wall Street Maverick.

“This transition will be seamless to our clients,” said Siebert, who will stay to get acquainted with customers. “It’s important to meet clients face to face.”
