I'm confused about something. According to his website, he was doing managed futures which means the funds were held in client accounts. How did he perpetuate this fraud? I see he got his start with Heartland Securities. They were a big daytrading firm in the 90's. BRIAN KIM Brian Kim, the founder and managing member of the General Partner and the Management Company, began his career as a proprietary trader in 1997 at Heartland Securities, a privately-held equity trading firm in New York. As an equity trader, he managed customer accounts utilizing the firmâs proprietary trading technology and methodology. In 1999, he joined First Security Investments, Inc. as a portfolio manager. In this role, Kim applied his knowledge of proprietary trading and portfolio management to customize private client portfolios. Since 2002, Kim has been developing Liquid Capitalâs Investment strategies and platforms. He received his B.A. in Economics from Dartmouth College in 1997.
