Zacks Investment Research is known for its proprietary Zacks Rank system, which rates stocks from 1 (Strong Buy) to 5 (Strong Sell) based on earnings estimate revisions. The system has a proven track record, with Zacks #1 ranked stocks historically outperforming the market by a significant margin.
The free tier provides basic stock quotes, Zacks Rank ratings, and limited research. Zacks Premium at $249/year adds the full stock screener, premium research reports, earnings calendars, and access to the complete Zacks Rank database with detailed scoring breakdowns.
Zacks is particularly strong for earnings-focused investors, providing comprehensive earnings estimate data, surprise history, and consensus estimates from Wall Street analysts. The stock screener lets users filter by Zacks Rank, value scores, growth scores, and numerous fundamental criteria.
