How David Einhorn Is Betting on Higher Inflation (AI-CIO.com) Inflation? What inflation? Hedge fund operator David Einhorn, who famously goes against the grain, is betting that the Consumer Price Index (CPI) will tick up in the US. Not a lot, mind you, but enough to give him a good result. Right now, inflation is muted. In the 12 months through mid-year, the CPI rose 0.6% after dipping 0.1% in May. To exploit what Einhorn sees as a more robust CPI ahead, his Greenlight Capital (assets: $7 billion) is taking positions in inflation swaps, which are derivatives based on Treasury inflation-protected securities (TIPS). His positions are in two-, five-, and 10-year swaps. In May, he wrote in a second-quarter letter to clients, those instruments implied annual CPI increases of just 0.1%, 0.8%, and 1.3%.
