[FinBERT: A Large Language Model for Extracting Information from Financial Text](https://bm.hkust.edu.hk/bizinsight/2026/01/finbert-large-language-model-extracting-information-financial-text)

We show that FinBERT incorporates finance knowledge and can better summarize contextual information in financial texts. Using a sample of researcher-labeled sentences from analyst reports, we document that FinBERT substantially outperforms the Loughran and McDonald
