"The managers featured in Drobny′s book use various strategies, as evidenced by the panoply of securities mentioned, from African stocks to Icelandic housing bonds. Drobny stresses the importance of diversification in picking global–macro managers, adding, "You can′t rely on one man."….Other managers featured in Drobny′s book include Peter Thiel, who runs Clarium Capital Management….Christian Siva–Jothy, former head of proprietary trading at Goldman Sachs, and Jim Leitner of Falcon Management. In the book, Leitner offers this advice to managers: "If you read about an oil discovery, start thinking about how to develop it into a trade. The idea is to do as much research as you can just reading and thinking about anything in the world before reaching out to your network."….The key to thriving in global macro? Plenty of smarts for starters. And "humility and flexibility," Drobny says. "You have to be flexible enough to cut your positions when what you firmly believe in is not working for you." This year, global macro managers did great in the January–April period, and didn′t do great in May and June, when equities and emerging markets took a big hit…..even for sophisticated players in the global–macro game, it sometimes pays to just sit on the sidelines."
