Hedge funds and asset managers increasingly rely on alternative data to generate and validate ideas. The question is not whether to use it, but which sources to use and how to combine them. Surveys show that a large majority of investment managers plan to increase their use of alternative data, and many already use at least two datasets. The following five source categories are among the most widely used and discussed in 2026.
1. Search and intent data
Search volume and search mix (what people look for on Google, Amazon, YouTube, and similar platforms) are used to gauge demand, interest in products or brands, and early shifts in behavior. Funds use this data to:
- Anticipate demand for a product or category before it shows up in sales or earnings
- Track interest in a company or theme over time
- Compare relative interest across competitors or regions
Search data is often normalized and mapped to listed companies or themes so it can be used in screens, models, or discretionary research. It is typically combined with other sources rather than used alone. Providers and platforms that offer multi-source search data (e.g. Paradox Intelligence) help funds avoid building and maintaining pipelines for each search product separately.
2. News and text sentiment
News sentiment, earnings-call sentiment, and other text-based signals are used to capture narrative shifts, event risk, and changes in how a company or sector is discussed. Common use cases include:
- Monitoring sentiment around earnings or events
- Detecting when a theme or company is moving from niche to mainstream (or the reverse)
- Flagging unusual spikes in negative or positive coverage
Sentiment alone is rarely a sufficient investment signal; it is often combined with price, fundamentals, or other alternative data. The value is in consistency (same methodology over time) and in pairing sentiment with behavioral or outcome data (e.g. search or traffic) to reduce noise.
3. Consumer and transaction data
Aggregated card data, receipt data, and other spending proxies are frequently cited as among the most valuable alternative data types for consumer and retail coverage. Funds use them to:
- Estimate demand or same-store sales ahead of announcements
- Compare growth rates across brands or categories
- Identify mix shifts or geographic differences
Access to this data is often expensive and subject to strict compliance and licensing. Many funds use it for a subset of names or strategies rather than as a universal input.
4. Web and app traffic
Website and app traffic, downloads, and engagement metrics are used to assess execution, demand, and competitive position for digital-first or digitally relevant companies. Use cases include:
- Tracking traffic to a company’s site or app relative to peers
- Monitoring conversion or engagement trends
- Supporting thesis work on market share or product adoption
Traffic data is often paired with search or sentiment to form a more complete picture of demand and narrative.
5. Social and engagement data
Data from social platforms (e.g. volume of mentions, hashtags, or engagement around a brand, product, or theme) is used to capture buzz, sentiment, and early adoption signals. Funds use it to:
- Gauge interest in a product launch or campaign
- Compare share of voice across competitors
- Identify emerging themes or viral content that may affect demand or narrative
Like sentiment, social data is usually used as one input among several. It can be noisy, so normalization and mapping to companies or themes improve usability.
How funds combine sources
Few strategies rely on a single alternative data source. The norm is to combine two or more: for example, search + sentiment, or transactions + traffic. The goal is to confirm that a signal is not an artifact of one dataset and to improve conviction before acting. Platforms that offer multiple sources in one place, with consistent identifiers and update schedules, reduce the integration burden and make it easier to run multi-signal workflows.
