Our Research. Your Success.

At the center of everything we do is a strong commitment to independent research and sharing its profitable discoveries with investors. This dedication to giving investors a trading advantage led to the creation of our proven Zacks Rank stock-rating system. For more than a quarter century, it has more than doubled the S&P 500 with an average gain of +23.68% per year. These returns cover a period from January 1, 1988 through August 5, 2024.

Helping investors find success has been the lifes 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.

With this crucial finding, he developed the Zacks Rank to harness the power of earnings estimates. Note this quantitative stock-rating system is purely mathematical. Were not influenced by Wall Street or some agenda to determine the ratings. So you can use this stock-selection tool to trade with confidence and accomplish your financial goals.

Today, were characterized by a team of experts who are passionate about your investing success. And everyone is focused on sharing the same reliable investment research they would want for themselves.

This has brought us to other breakthroughs such as:

  • Price Response Indicator: Shows what a stock price is likely to do after an earnings report.
  • Most Accurate Estimate: Knowing the earnings consensus for a stock is nice. Being one of the few that knows the Most Accurate Estimate is even better.
  • Earnings ESP (Expected Surprise Prediction): Determines the likelihood of an earnings surprise BEFORE its reported.
  • Zacks Equity Research: Professional-grade research that combines quantitative models with insight provided by our equity analysts.
