Money circulates through a multiplicity of financial markets at a dizzying speed and on a global scale. To make sense of the complicated world of high finance, this lively program profiles some of the people who keep the money moving. Nobel Laureate James Tobin, best-selling author John Murphy, fund managers, scholars, and day traders are captured at MIT Sloan, Yale University, Firebird Management, London’s foreign exchange market, the École Polytechnique in France, and trading rooms in the U.S. and Europe. Lending liquidity, handling mutual funds, stock speculation, charting, model-driven trading, and other topics are covered. (53 minutes)
