History

Cambridge Investment Research was founded in 1985 by Eric Schwartz. As of 2010, it was still controlled by its founder, and was one of the biggest brokerage dealers in the U.S.
In April 2016, the U.S. Securities and Exchange Commission charged Cambridge Investment Research Advisors with failing to adequately supervise an employee who defrauded at least 47 advisory clients and engaged in unsuitable trading in some clients’ accounts. The company settled the case by paying a $225,000 penalty.
In January 2017, Schwartz stepped out of the CEO role and was made executive chairman, and Amy Webber was made CEO in addition to her role as president.
As of 2017, the company was re-structured as a holding company, Cambridge Investment Group, Inc., that comprised multiple broker-dealers and registered investment adviser subsidiaries, including: Cambridge Investment Research Advisors, Inc. and Cambridge Investment Research, Inc.
