LEADING INDICATORS
Built from Custom Web-Based Data Pipelines

Potent Pages designs and operates custom web crawling systems that generate proprietary leading indicators. The goal is simple: earlier visibility into real-world activity using durable, repeatable data collection that your fund controls.

  • Proprietary signals, not vendor feeds
  • Long-run persistence and monitoring
  • Structured time-series delivery
  • Backtest-ready pipelines

Why leading indicators matter

Leading indicators are forward-looking signals that change before price, revenue, or reported fundamentals adjust. For hedge funds, the advantage is not just access to information. It is the ability to observe real-world behavior early, continuously, and in a way that competitors cannot easily replicate.

Practical lens: A signal is valuable when it is early, repeatable, and aligned with your time horizon. The data must persist long enough to validate, backtest, and operationalize.

From raw web data to investable signals

Public websites contain structured and semi-structured information that reflects real economic activity. When collected systematically and normalized over time, this becomes a foundation for leading indicators. Potent Pages focuses on building pipelines that translate messy web sources into clean, structured datasets suitable for research.

Inventory depletion velocity

Track in-stock to out-of-stock transitions across retailers to infer demand strength and supply constraints.

Pricing and discount behavior

Monitor promotions, markdown depth, and regional dispersion to detect margin pressure and competitive responses.

Hiring dynamics

Measure posting cadence, time-to-fill signals, and role churn to identify expansion or contraction patterns.

Review and sentiment momentum

Quantify changes in review volume and sentiment to detect demand inflections earlier than reported sales.

Why custom data instead of vendor feeds

Commercial alternative datasets can be useful for exploration, but competitive signals rarely remain competitive after broad distribution. Funds often move to custom data acquisition to preserve exclusivity, auditability, and control over the universe and schema.

  • Vendor signals become consensus quickly.
  • Methodologies are often opaque and hard to audit.
  • Universes and definitions shift without notice.
  • Data availability can disappear when vendors pivot.
  • It is difficult to adapt the dataset to a specific thesis.
Custom advantage: You own the crawler logic, the collection process, and the resulting signal. That ownership matters when you need stability over years, not weeks.

How Potent Pages builds production-grade pipelines

Potent Pages does not sell prepackaged datasets. We build and operate data systems designed around your use case. The emphasis is durability and operational reliability, so the pipeline continues to function as websites change.

1

Signal definition and feasibility

Clarify the hypothesis, universe, cadence, and backtest requirements, then validate sources and collection paths.

2

Crawler design and change detection

Engineer site-specific collection that handles modern web stacks, including JavaScript-heavy pages when needed.

3

Normalization and schema enforcement

Transform raw captures into consistent tables and time-series datasets with versioned schemas and validation rules.

4

Monitoring, alerting, and continuity

Detect breakage early, repair quickly, and preserve historical continuity for research and production signals.

5

Delivery to your workflow

Deliver via database, API, or flat files, aligned to your research stack and scheduling expectations.

What makes a leading indicator investable

Not all alternative data is useful. For a leading indicator to be investable, it needs operational integrity and analytical clarity. We build pipelines that support these requirements from day one.

  • Persistence: Collection that can run for months or years.
  • Low latency: Capture events quickly enough to matter.
  • Stable definitions: Versioned schemas and controlled changes.
  • Bias control: Practices that reduce survivorship bias and universe drift.
  • Backtest-ready outputs: Structured data that supports validation.
  • Economic intuition: A clear rationale for why the signal should lead outcomes.

Build a signal you can own

If your fund is exploring non-consensus signals derived from web-based data, we can help design and operate a pipeline built for durability, scale, and research credibility.

Web Crawlers

Data Collection

There is a lot of data you can collect with a web crawler. Often, xpaths will be the easiest way to identify that info. However, you may also need to deal with AJAX-based data.

Development

Deciding whether to build in-house or finding a contractor will depend on your skillset and requirements. If you do decide to hire, there are a number of considerations you'll want to take into account.

It's important to understand the lifecycle of a web crawler development project whomever you decide to hire.

Web Crawler Industries

There are a lot of uses of web crawlers across industries to generate strategic advantages and alpha. Industries benefiting from web crawlers include:

Building Your Own

If you're looking to build your own web crawler, we have the best tutorials for your preferred programming language: Java, Node, PHP, and Python. We also track tutorials for Apache Nutch, Cheerio, and Scrapy.

Legality of Web Crawlers

Web crawlers are generally legal if used properly and respectfully.

Hedge Funds & Custom Data

Custom Data For Hedge Funds

Developing and testing hypotheses is essential for hedge funds. Custom data can be one of the best tools to do this.

There are many types of custom data for hedge funds, as well as many ways to get it.

Implementation

There are many different types of financial firms that can benefit from custom data. These include macro hedge funds, as well as hedge funds with long, short, or long-short equity portfolios.

Leading Indicators

Developing leading indicators is essential for predicting movements in the equities markets. Custom data is a great way to help do this.

GPT & Web Crawlers

GPTs like GPT4 are an excellent addition to web crawlers. GPT4 is more capable than GPT3.5, but not as cost effective especially in a large-scale web crawling context.

There are a number of ways to use GPT3.5 & GPT 4 in web crawlers, but the most common use for us is data analysis. GPTs can also help address some of the issues with large-scale web crawling.
