Michael Covel talks to Francisco Vaca of Vaca Capital Management. A math whiz from an early age, Vaca first pursued a career as a particle physicist. Always intrigued by the financial markets, Vaca started an investment club with his family while pursuing his Ph.D., and his scientific background led him to a "stats" approach to investing. When institutional funding stood in the way of working on a particle accelerator, a unique opportunity to work in the financial markets beckoned. After answering a mysterious newspaper advertisement in 1996, Vaca ended up working at the legendary C&D Commodities (see book: 'The Complete TurtleTrader'); he was handed a copy of Jack Schwager's 'Market Wizards', and quickly realized the achievements of his new employers. Vaca and Covel also get to the bottom of the source of profits in the futures markets; why people who are on the losing side of trades still play the game; the importance of diversification; and why you should take every signal you can. Pay attention, Vaca brings wisdom (see: www.vacacm.com). Special Offer: receive free DVD delivered to your home or office: www.trendfollowing.com/win.
