Currently Seeking New Role· New York, New York, United States
I am currently seeking a new role in the alternative investments space.I have been working directly with funds of hedge funds (FoHFs) for nearly five years, and learned of the industry while working at Bloomberg LP. In the time spent as an analyst at Measurisk I became knowledgeable of the concepts and tools used to quantitatively measure single hedge fund and FoHFs financial market risk. In my role at Octane I was responsible for the sourcing and monitoring of boutique FoHFs managers. Octane's qualitative due diligence process is well-respected within the industry and I learned a lot from the rigorous analysis. I hold the Chartered Alternative Investment Analyst (CAIA) designation and plan to sit for Level I of the Financial Risk Manager (FRM) exam in November 2009. My ideal new role would be that of a FoHFs analyst participating in the qualitative and quantitative due diligence process. I would also like to leverage my risk background in the new position. The current market dictates flexibility so I am also considering roles that will help me further my understanding of what it takes to be a great investment manager. Lastly, I would prefer to remain in the New York metro area.
