About Zacks

Company Profile

Zacks is a privately owned 550 person Chicago-based firm with 30 years of experience providing U.S. equity investors with the investment information required to operate their investment processes. Since its founding in 1978 as a provider of consensus EPS forecasts, Zacks has expanded its services to US equity investors to encompass the full range of investment information, research and tools required to effectively manage individual and institutional US equity investment processes

Zacks now provides investment data, market data systems, proprietary quantitative models and analyst written research to institutional investors, brokerage firms, individual investors and corporations.

Zacks has been a leader in innovation. In 1981 Zacks originated the concept of the EPS surprise based on consensus estimates of quarterly earnings and in 1982 expanded the EPS surprise to create the Zacks Rank, our proprietary 1-to-5 stock scoring system, whose #1 ranked stocks have generated an average return of over 30% per year over the last 25 years. The proven ability of the Zacks Rank to statistically predict the future relative performance of groups of stocks is the core of many of our services today.

1performance is based on equal weighted portfolios, re-balanced monthly with zero transaction costs
