Auerbach Grayson, a New York-based brokerage, is to be the first international company to sell Iraqi securities since the 2003 invasion, after it signed an agreement with Rabee Securities, a Baghdad brokerage, through which it will provide trade execution and research on companies traded on the Iraq Stock Exchange to US investors. Rabee is run by Shwan Ibrahim Taha, a former fund manager with Templeton Asset Management who also once ran a hedge fund for George Soros.
