Zacks Investment Research

Zacks is built around one core insight: earnings estimate revisions are the most powerful force driving stock prices. The Zacks Rank — which rates stocks 1 (Strong Buy) to 5 (Strong Sell) based primarily on earnings estimate momentum — has an audited track record of outperforming the market. Zacks #1 Ranked stocks have averaged +24.3% per year since 1988.

The platform provides earnings estimates, analyst recommendations, financial data, and a stock screener that filters on the Zacks Rank and related metrics. Zacks Premium ($249/year) adds the Zacks Rank for all stocks, Focus List portfolio, Equity Research reports, and a premium screener.

Zacks' emphasis on earnings revisions is based on decades of academic research showing that analyst upgrades and earnings surprises predict future stock returns. For investors who want a systematic, quantitative approach to stock selection based on the single most predictive factor in equity returns, Zacks delivers.
