Founded in 1923, Rosenthal Collins Group (RCG) was one of the oldest and largest independent Futures Commission Merchants in the United States. For nearly a century, the firm provided comprehensive clearing, execution, and brokerage services for a global client base trading in futures and options on futures. Known for its personalized service and robust infrastructure, RCG catered to a diverse clientele including institutional traders, commercial hedgers, and individual investors. In January 2019, the customer business of Rosenthal Collins Group was acquired by the UK-based brokerage Marex Spectron, and RCG ceased its independent operations.
