Founding Editor, Systems & Forecasts
Founder, Signalert Asset Management
Gerald founded Signalert in 1973 after several years’ experience as a financial columnist and trader for his own account. He was among the pioneers of using technical analysis to trade mutual funds with the goal of increasing the safety of normally risky stock market investments. Among his many contributions to the field is his invention of the MACD indicator in the late 1970s, which is still widely used by traders.
At the time he founded Signalert, Gerald was a practicing psychotherapist. He graduated Brooklyn College and did his graduate studies at New York University.
