Zacks
Earnings estimates and analyst research. Factual profile only: no rankings, no ratings.
Last updated Oct 2, 2026
What it does
Zacks Investment Research is built around earnings estimate data. Its core idea is that revisions to analyst earnings estimates tend to move stock prices, so the site tracks how estimates change and groups stocks with its Zacks Rank system.
Alongside the rankings, Zacks publishes analyst-written research reports, market commentary, and earnings calendars, and it maintains mutual fund and ETF research. The site's long history in estimate tracking makes it a standard reference for earnings-focused investors.
Who it is for
Investors who follow earnings closely use Zacks to see how analyst estimates are trending for the stocks they own. Value and momentum investors use the ranking system as one input in their screening.
Readers who want professional research without a brokerage account use the site's published reports and commentary. Fund investors use its mutual fund and ETF pages for performance data and analyst views.
Key capabilities
The Zacks Rank assigns stocks to categories based on earnings estimate revisions, updated as analysts change their forecasts. Earnings calendars track upcoming reports and past surprises.
Research reports cover individual stocks, industries, and market themes. Fund and ETF pages include performance data and analyst commentary, and the site publishes daily market commentary from its analysts.
