In 1978 Len Zacks published a seminal article which first documented the value of using earnings estimate revisions to select stocks. A few years later we originated the concept of the EPS surprise which has now become widely used in the investment industry. This work led, in 1982, to the development of the Zacks Performance Rank (view PDF), a proven, proprietary stock-ranking model which is the core of the Zacks Investment Philosophy. At Zacks, a staff of PhDs develops and refines our own proprietary quantitative models and reviews hundreds of academic investment research articles each year in order to uncover new insights into making investment decisions.

Over the past 25 years, the core of our investment management process remains unchanged. The most important fundamental factor affecting stock prices is earnings. The changes in stock values, over time, have always been attributable to earnings. Our studies of analyst estimate revisions have proven to be the most powerful leading indicator in forecasting and predicting material changes in earnings. The end result is an active management approach that has generated which we believe to be exceptional results and we will continue to adhere to this discipline in all market cycles.
