In 2008, Mr. Gerber developed the Gerber Statistic, which measures the co-movement of financial assets, enabling early detection of concentration risks and insufficient diversification within an absolute return portfolio. Later, after many years in collaboration with Harry Markowitz, the Nobel Prize-winning economist and father of Modern Portfolio Theory , research was completed to optimize the modern portfolio construct by replacing historical covariance with the Gerber Statistic.
Mr. Gerber began his investment career in 1991, as a member of the American Stock Exchange working as an equity options market maker. In 1997, he founded Gerber Asset Management LLC to develop and engage in proprietary investment strategies, many of which are utilized by Hudson Bay Capital today. In late 2005, Mr. Gerber and Yoav Roth co-founded Hudson Bay Capital, which absorbed GAM’s business and 15 employees.
