textsfinance

Textsfinance is an interdisciplinary concept describing the use of textual data for financial analysis and decision making. It encompasses methods and practices that extract structured information from unstructured texts to support investment research, risk management, regulatory compliance, and market monitoring. The term often refers to the application of natural language processing, machine learning, and information extraction to sources such as financial news articles, earnings call transcripts, regulator filings (for example, company annual reports and 10-K/10-Q documents), central bank communications, analyst reports, and social media posts.

Typical workflows include data collection and cleaning, sentiment or event detection, topic modeling, and the construction of signals or indicators for downstream models. Applications include generating trading signals, forecasting macro variables, assessing credit or liquidity risk, detecting fraud or market manipulation, and monitoring reputational risk.

Challenges include data quality and noise, labeling scarcity, domain-specific language, imbalanced signals, multilingual text, and regulatory and ethical considerations such as privacy and fair disclosure. Evaluation relies on labeling accuracy, backtesting of signals, and predictive performance of downstream tasks, with emphasis on robustness and interpretability.

The field has grown with advances in NLP and access to large financial text corpora, but it remains diverse and non-standardized across institutions. Researchers and practitioners emphasize transparent methodologies, reproducible experiments, and careful validation when applying textsfinance to real-world decisions.
