Zacks Investment Research is one of the largest providers of independent stock, ETF and mutual fund research in the U.S. The performance of our stock research recommendations has consistently ranked among the top research firms in the U.S. by independent evaluators of equity research. This research anchors our active trading services, long-term investor services, and powerful resources and tools.

At the center of everything we do is a strong commitment to independent research and sharing its profitable discoveries with investors. In fact, helping investors find success has been the life's work of our Founder and CEO, who in 1978 armed with his PhD from MIT, hit upon a key discovery:

Earnings estimate revisions are the most powerful force impacting stock prices.

This crucial finding led to the creation of our proven Zacks Rank stock-rating system that harnesses the power of earnings estimates. Since 1988, the private Zacks #1 Rank List has more than doubled the S&P 500.
