Abstract

fetched live from OpenAlex

This study examines the ability of security analysts to provide objective earnings forecasts for firms with which the analyst’s brokerage firm has a director affiliation. The affiliation that we examine is where the brokerage firm has, on its board of directors, a director or an upper management individual from the firm which an analyst at the brokerage firm provides coverage. We find that affiliated analysts tend to provide earnings forecasts that are insignificantly different from unaffiliated analysts in terms of accuracy. However, we also find that forecasts provided by affiliated analysts tend to be significantly more pessimistic than those provided by their unaffiliated counterparts. This pessimistic bias in their earnings forecast will more easily allow the covered firm to beat earnings expectations when earnings are realized. We find that this bias surfaced after the Global Settlement decision, an enforcement agreement between large investment banks and the Securities and Exchange Commission (SEC) regarding issues surrounding conflicts of interest.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
