Odd Lots

Financial markets around the world are stuck in a long period of low volatility and boredom. But one pocket is seeing some wild action -- grains. Spring wheat (a form of high-protein wheat grown in the northern Midwest) has been on a tear, alongside action in soy and corn. What explains the whipsaw? Joe and Tracy speak with Tommy Grisafi, a longtime trader who works as a risk manager at Advance Trading, a firm that helps farmers take advantage of financial markets. Grisafi walks us through the history of the market, how technology is dramatically changing things and why things have suddenly gotten so darn volatile.
