Abstract
Predicting rare events in financial markets is a major challenge, and the traditional models of predicting extreme price Features haven't worked well for drastic price changes. The study presents a novel model for timing and forecasting unusual equity returns, particularly a 30% rise in ten trading days. Additionally, the methodology employs a two-stage pipeline that combines an advanced machine learning classification algorithm or model, such as Gradient-Boosting, Random Forest, or Support Vector Machine, with a Generalized Additive Model (GAM) to interpret nonlinear feature extraction. The most challenging issues in financial prediction are also taken into account by the framework, such as class imbalance using unique prediction metrics like PR-AUC (Area Under the Percision-Recall Curve) and Precision at K and dynamic risk control using quantile-based take-profit and stop-loss strategies. With a PR-AUC of 0.72—much higher than that of conventional techniques—the analysis shows that XGBoost produces better results. By providing a solid, logical framework for forecasting infrequent occurrences in erratic markets, the study advances our understanding and has applications for algorithmic trading patterns and risk management instruments.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
