He is comfortable analyzing large data sets and uses a variety of statistical and analytic techniques for pulling the meaning out of data. For over 24 years, Jack has been involved in finance and the securities markets, including: 10 years in Merrill Lynch’s Private Client Group in a high net worth team; founding and operating his own registered investment advisory firm; managing a family office for a $100 million net worth family; and starting and managing a global macro hedge fund investing in equities, fixed income, currencies, and commodities.
