Abstract

fetched live from OpenAlex

Forecasting firms ’ earnings has long been an interest of market participants and academics. Tra-ditional forecasting studies in a multivariate time series setting do not take into account that the timing of data release for a specific time period of observation is often spread over several days or weeks. This paper focuses on the separation of announcement timing or data release and the use of econometric real-time methods, which we refer to as an updated vector autoregression (VAR) fore-cast, to predict data that have yet to be released. In comparison to standard time series forecasting, we show that the updated forecasts will be more accurate the higher the correlation coefficients among the standard VAR innovations are. Forecasting with the sequential release of information has not been studied in the VAR framework, and our approach to the six Canadian banks shows its value. By using the updated VAR forecast, we find that the relative efficiency gain is 33 % in the one-step-ahead forecast compared to the ordinary VAR forecast, and 7 % compared to profes-sional consensus forecasts. Thought experiments suggest that if banks ’ order of information release were to change, forecast errors could be substantially reduced. These experiments emphasize that evaluating the release ordering is crucial in determining forecast accuracy.

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.
