When most people analyze the stock market, they look at stuff like revenues, earnings, valuations, and economic conditions. But some people like to look at the Billboard music charts or what kinds of films are popular at any given moment. On this week's Odd Lots, we talk to Matt Lampert, the director of research at the Socionomics Institute, which attempts to analyze the market by looking at the nation's social mood. And there's no better way to examine society's mood than by looking at pop culture. Are horror movies in vogue? Are people listening to upbeat pop songs? Each of these things, according to Lampert, can offer a clue about the state of the nation and therefore which way the market will go next.
