Capabilities

Extract financial alpha with zero infrastructure overhead

Our Zacks scraper handles complex HTML table structures, dynamic charts, and financial data normalisation. We manage the proxy rotation and session limits to deliver clean quantitative data directly to your models.

Zacks Rank Extraction

Capture the proprietary 1 to 5 Zacks Rank for thousands of equities, updated daily before market open.

Earnings ESP Tracking

Extract the Expected Surprise Prediction percentage to identify stocks likely to beat or miss consensus estimates.

VGM Style Scores

Scrape Value, Growth, and Momentum letter grades alongside the composite VGM score for granular factor modelling.

EPS Estimate Revisions

Track upward and downward estimate revisions across 7-day, 30-day, and 60-day windows to capture analyst sentiment shifts.

Industry & Sector Ranks

Extract the Zacks Industry Rank and Sector Rank to build top down rotation strategies.

Broker Rating Distributions

Capture the exact breakdown of Strong Buy, Buy, Hold, Sell, and Strong Sell recommendations from covering analysts.

Dividend & Yield Data

Scrape historical dividend payouts, current yields, and 5-year dividend growth rates for income portfolios.

Mutual Fund & ETF Ranks

Extract fund specific metrics including the Zacks Mutual Fund Rank, expense ratios, and asset allocation breakdowns.

Market Hours Scheduling

Configure pipelines to run immediately after market close or just before market open to ensure data freshness for trading models.

Under the hood

Overcoming financial data extraction hurdles

Financial portals deploy strict rate limits and complex DOM structures. Here is how we ensure reliable delivery of Zacks market data.

Intelligent request throttling and proxy rotation

Financial websites aggressively throttle IPs that request too many ticker pages in sequence. We use US residential proxies and apply randomised delays between requests to blend in with retail investor traffic, ensuring complete universe coverage without blocks.

Data normalisation
Parsing legacy HTML structures

Much of Zacks data is embedded in dense, nested HTML tables rather than clean APIs. Our extraction logic maps specific table cells to strict schema fields, handling missing values and structural inconsistencies across different asset classes.

Market timing
Precision scheduling around market hours

Stale financial data is useless. We orchestrate pipelines via Apache Airflow to trigger extraction jobs exactly when Zacks updates its daily ranks, guaranteeing your models ingest the latest estimate revisions before the opening bell.

Change detection
Isolating rank upgrades and downgrades

Instead of processing the entire dataset daily, we can compute diffs against previous runs. This allows us to emit lightweight webhook payloads specifically when a ticker experiences a Zacks Rank upgrade or downgrade.

Type safety
Strict financial type enforcement

A string where a float should be breaks trading models. We enforce strict data types during the validation phase, stripping currency symbols, converting percentages to decimals, and handling 'N/A' values appropriately before delivery.

Applications

Who uses Zacks data and how

Teams across industries use zacks.com data to build competitive products and smarter operations.

01
Quantitative Trading Models

Systematic funds ingest daily Zacks Ranks and EPS estimate revisions as alpha factors in multi-factor equities models.

02
Earnings Surprise Prediction

Analysts monitor the Zacks ESP metric combined with recent broker rating changes to position portfolios ahead of earnings calls.

03
Factor Investing

Asset managers screen thousands of equities using VGM Style Scores to construct portfolios tilted towards Value or Momentum.

04
Equity Research

Fundamental analysts track long term EPS estimate trends and industry rank changes to validate qualitative investment theses.

05
Financial App Aggregation

Fintech platforms enrich their user facing ticker pages with consensus analyst ratings and dividend yield histories.

06
Risk Management

Risk teams monitor sudden downward estimate revisions or rank downgrades across portfolio holdings to trigger review alerts.

Why DataFlirt

"Zacks holds the industry standard for earnings estimate revisions and surprise predictions, but extracting that alpha requires a resilient extraction pipeline."

Financial data decays rapidly. Relying on manual exports or fragile scripts means missing critical rating changes. DataFlirt builds production grade pipelines that handle Zacks rate limits and complex table structures, delivering clean market data directly to your quantitative models before the opening bell.

Common questions.

About zacks.com scraping, legality, and pipeline operations.

Ask us directly →
Is scraping Zacks legal?

Scraping publicly available financial data is generally permissible under applicable law. DataFlirt extracts only public, non authenticated data such as the public Zacks Rank, ESP metrics, and consensus estimates. We do not bypass paywalls to access Zacks Premium or Ultimate content. Clients should review terms of service and consult legal counsel for specific trading use cases.

How fresh are the Zacks Ranks and estimates?

We typically schedule extraction pipelines to run daily, immediately after Zacks updates its ranks and estimates. This ensures your models have the latest data before the US market opens.

Can you track historical changes in the Zacks Rank?

Yes. Every pipeline run produces a timestamped snapshot. Over time, this builds a time series dataset allowing you to backtest strategies based on Zacks Rank upgrades and downgrades.

Do you extract data for mutual funds and ETFs?

Yes. Our pipelines can extract the Zacks Mutual Fund Rank, ETF profiles, expense ratios, and asset allocation data alongside standard equities.

How do you handle missing values or 'N/A' in the data?

Financial data often contains gaps. Our validation layer enforces strict typing. Missing numeric values are explicitly cast to null rather than left as string artifacts, ensuring downstream quantitative models do not break.

What is the minimum viable engagement for Zacks data?

We typically start with a defined universe, such as the Russell 3000 or S&P 500, delivered daily. Pricing scales based on the number of tickers tracked and the frequency of extraction.

Can I get a sample of the extracted data?

Yes. We offer a sample run for a subset of tickers during the scoping phase. This allows your quant team to validate the schema, data types, and completeness before committing to a production pipeline.
