His father, Joseph Dreman, was a prominent trader on the Winnipeg Commodity Exchange for many years.
[1] After graduating, he worked as director of research for Rauscher Pierce, senior investment officer with Seligman, and senior editor of the Value Line Investment Service.
In 1977, he founded his first investment firm, Dreman Value Management, LLC., and has served as its president and chairman.
[2] In 2009 his firm chose to hold on to banking stocks as they were crashing, in line with his contrarian value investing philosophy.
As a result, his firm was removed from management of his flagship DWS Dreman High Return Equity Fund by the board of Deutsche Bank, citing weak performance.
