CUSTOM ALTERNATIVE DATA
For Macro Hedge Funds and Global Macro Research

Potent Pages builds custom web crawling systems and data pipelines that turn public-web signals into structured, backtest-ready datasets. Capture policy shifts, real-economy activity, and geopolitical risk earlier using data your fund controls.

  • Proprietary datasets, not shared feeds
  • Change-tracked history and revisions
  • Cross-asset macro use cases
  • Production-grade monitoring

Why macro hedge funds build custom alternative data

Macro funds operate across rates, FX, commodities, equities, and volatility. The best opportunities often emerge when policy direction changes, supply chains break, inflation dynamics shift, or geopolitical risk accelerates.

Traditional datasets and vendor feeds can be useful, but they are increasingly commoditized. Custom web-based collection gives you control over definitions, cadence, and historical continuity. That control matters when you need signals that persist long enough to validate and deploy.

Core idea: Custom alternative data helps you observe real-world behavior directly, instead of waiting for a monthly release or relying on a dataset every peer can buy.

What “custom macro data” looks like in practice

Public websites contain structured and semi-structured signals that reflect economic activity, policy posture, and risk perception. When captured consistently, normalized, and change-tracked, this becomes a foundation for proprietary macro indicators.

Policy and central bank shifts

Monitor statement deltas, speeches, calendars, and subtle language changes that signal forward guidance shifts.

Real-economy activity proxies

Track pricing, inventories, shipping flows, hiring, and production signals that move before official macro releases.

Inflation pressure indicators

Measure product-level price changes, discount depth, and supply constraints to estimate inflation before it prints.

Geopolitical and trade risk

Detect escalation patterns, sanctions exposure, chokepoint stress, and regional instability through curated sources.

Track economic, fiscal, and monetary policy signals in real time

Macro markets often move on expectations, not releases. Timing advantage comes from monitoring changes continuously and capturing revisions, not simply reading headlines after the fact.

  • Government agencies: Employment, inflation, GDP, fiscal announcements, and revision history.
  • Central banks: Statements, minutes, pressers, speeches, and forward guidance deltas.
  • Regulators: New rules, enforcement posture, and policy implementation details.
  • News feeds: Curated, topic-scoped sources with alerting when narrative velocity changes.
Upgrade over “monitoring”: We can track exact content changes over time so your research can quantify how language and posture evolves.

Gauge public and political sentiment at scale

Macro outcomes are influenced by sentiment around inflation, growth expectations, political legitimacy, and social stability. Crawlers can capture sentiment across platforms, regions, and languages to quantify narrative shifts.

  • Social platforms: Topic-specific tracking to measure narrative acceleration and divergence.
  • Forums and communities: Niche sentiment signals that often lead mainstream coverage.
  • News comments: Useful for consumer and political mood indicators in specific regions.
Macro lens: Instead of simple positive vs negative scoring, focus on topic clustering, velocity, and geographic dispersion.

Build proprietary macro indicators using alternative data

Alternative data is most useful when it becomes a repeatable time series aligned to a hypothesis. Custom crawlers can generate indicators that complement traditional releases and reduce reliance on crowded vendor signals.

  • Supply chain stress: Shipping activity, port congestion, delays, and route disruptions.
  • Consumer demand: Real-time pricing, availability, and discount behavior across retailers.
  • Labor market: Hiring intensity, wage signals, and sector-level vacancy dynamics.
  • Energy and commodities: Production disclosures, export constraints, infrastructure disruptions.
Backtest-ready output: The goal is clean, normalized data with consistent definitions that supports validation and research workflows.

Identify structural trends and second-order macro effects

Macro investing often depends on understanding how structural shifts propagate. Crawlers can track changes across industries and regions to surface second-order effects that impact growth, inflation, and capital flows.

  • Industry publications and regulatory changes that reshape competitive dynamics.
  • Corporate disclosures, partnerships, and product roadmaps that signal capital allocation shifts.
  • Trade policy and sanctions activity that changes routing, sourcing, and pricing behavior.

Monitor geopolitical and trade risk globally

Geopolitical risk is a direct driver of volatility regimes. Crawlers can track curated sources to surface early signals of escalation, disruptions to trade routes, and policy changes that matter for cross-asset positioning.

  • News and official sources: Conflict progression, elections, sanctions, and diplomatic posture.
  • Regional sentiment: Early indicators of instability through localized discourse.
  • Trade chokepoints: Watchlists for shipping lanes, ports, and routing constraints.

Flag governance issues and systemic credibility risks

Even for macro strategies, credibility issues can matter at the sector or jurisdiction level. Crawlers can detect signals of governance failure, regulatory pressure, and reputation deterioration that may contribute to broader systemic risk.

  • Regulatory filings and disclosures for anomalies and methodology shifts.
  • Investigative reporting and negative press trend monitoring.
  • Public allegations, whistleblower chatter, and risk narrative formation.
