MacroSignal — An Enhanced Macro-Driven Machine Learning Framework for Equity Selection
Bibliographic record
Abstract
Classical equity selection prioritizes firm-specific attributes, such as valuation multiples and momentum signals. However, the background of macroeconomic dynamics is usually neglected. When changes in economic regimes, money policies, or unexpected inflation occur, usual factor models are no longer valid. This study develops a macro-driven machine learning framework: MacroSignal. It consists of six key macroeconomic indicators: GDP growth, CPI, M2, federal funds rate, unemployment rate, and industrial production, combined with the classical financial features to predict the 5-day stock returns. There are 21 stocks in the U.S market taken during different market cycles from 2015 to 2025. Based on similar attributes, two versions of modelling have been constructed: binary and multi-class. The binary model performs better than the multi-class version–by about 68% against 54%. Money supply growth is the most powerful predictor and thus implies that individual stocks are directly influenced by Fed Policy. About 11% excess return is generated by this framework during the turbulent times of 2020-2021, thereby indicating its truly practical value.

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.
