The signal

NLP scoring of news, press releases, filings, earnings-call transcripts and social posts into machine-readable tone, novelty and event signals per company. The category converts unstructured text flow into quantitative inputs that investment models can consume at scale.

Information reaches prices with a lag, so shifts in media tone and story novelty anticipate short-horizon returns, volatility spikes and reversal windows. Funds use sentiment momentum around earnings, controversy screens as risk overlays, and transcript-tone deterioration to flag weakening fundamentals before estimate revisions. Story-level deduplication ensures a single scoop is counted once rather than once per syndicated copy. Article-level records carry entity tags, relevance scores, sentiment scores and event labels (guidance changes, litigation, management departures), together with source metadata and links. Aggregation layers produce company-day sentiment, momentum and novelty series plus cross-sectional dispersion measures. Vendors increasingly ship factor-ready outputs such as controversy indices and earnings-call tone deltas.

Pipelines ingest licensed newswires, regulatory feeds, transcript services and social APIs, then tag entities using curated dictionaries with disambiguation by ticker and corporate hierarchy. Language models tuned for financial tone score each item; established vendors publish dozens of sentiment-related fields per entity and cover a dozen or more languages. Point-in-time discipline is central: timestamps reflect publication time, and dictionaries and models are versioned so backtests remain reproducible.

Caveats and compliance

Sentiment scores are model-dependent and unstable around sarcasm, hedging and translated text. Coverage volume scales with market capitalization, so unnormalized activity proxies company size rather than information. Clustering errors double-count events, and silent vendor model upgrades can rewrite historical values.

Redistributing article text requires publisher agreements, while derived scores are generally safer to ship. Social-media ingestion adds platform terms-of-service constraints, and text-and-data-mining exceptions in EU copyright law do not override contractual restrictions.

Who uses this signal

Quantitative equity funds consume sentiment and novelty scores as model features; event-driven desks monitor controversy and novelty alerts around catalysts. Risk teams apply negative-news screening to portfolios and counterparty surveillance.
