Reading between models

Does a language model see something FinBERT misses?

Shared signal. Different readers.186 firms. 55 months. One harder question.
01 / THE QUESTION

What this explores

A study of large language model and FinBERT sentiment on UK regulatory disclosures, separating shared sentiment from model disagreement.

02 / THE APPROACH

How it comes together

Score the same disclosures with both models, separate common sentiment from disagreement, then examine subsequent returns and portfolio performance.

03 / WHERE IT STANDS

Evidence before claims.

Model disagreement did not show reliable next-month predictive value. Transaction costs are central to interpreting portfolio results.

04 / SUPPORTING MATERIAL

This is the design preview. Reports, repository links and demos will be connected when the publication-ready materials are supplied.
