Abstract

fetched live from OpenAlex

After the completion of a merger and acquisition (M&A) transaction, the target firm is delisted, but some analysts who covered it retain coverage of the merged firm. We hypothesize that this decision is based on two factors: the analyst's ability to cover the merged firm and his or her assessment of the M&A deal. Consistent with these hypotheses, we find that the remaining target analysts provide more accurate earnings forecasts and more optimistic stock recommendations and growth forecasts for the merged firms than do the remaining acquirer analysts. We also find that a higher percentage of target analysts choosing to cover the merged firm is associated with better operating and long-term stock performance of that firm, but we do not find this relation with acquirer analysts. Our results extend the literature by showing that target analysts' coverage decisions reveal valuable information about a merged firm's future performance. This paper was accepted by Wei Jiang, finance.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
