This student won elite hedge fund investing contest

Marc Grow, a student at Columbia Business School, won this year's idea contest at the Sohn Investment Conference, beating out many others, including professionals, in the eyes of a hedge fund all-star judging panel that included Bill Ackman and David Einhorn.

Grow sat down with CNBC's Scott Wapner to explain how he came up with his idea and what it was like to present in front of the 3,000-plus attendees of the prestigious New York conference.

Each year at Sohn, students, analysts and other new finance professionals submit an investment thesis to a panel of prominent hedge fund managers, who then select the winner based on the soundness of the analysis and 12-month return potential.
