A Workflow for Multi-Factor Research with VeighNa Alpha

Summary

This overview introduces VeighNa’s alpha research framework as a linked workflow for equity research: organize local market and constituent data, build factor and label datasets, train prediction models, generate scores, and test portfolio strategies. It explains the responsibilities of the research workspace, dataset, model, and strategy components. Dataset preparation includes common cross-sectional steps such as missing-value handling, standardization, outlier treatment, and ranking; the modeling examples include linear, tree-based, and neural network approaches. A strategy layer converts scores into holdings, with a top-ranked portfolio offered as an example.

The article also lists basic environment concepts, dependencies, data preparation notebooks, and full workflow examples, and recommends starting with data setup before running a complete model pipeline. It is an introductory map rather than a comparative evaluation: it reports no model performance, trading results, or evidence that any listed factor set or model is superior. Readers still need suitable historical data and must define and validate their own labels, portfolio rules, and out-of-sample evaluation.

Key ideas

• The framework connects local data preparation, factor and label construction, model prediction, and portfolio backtesting.
• The research workspace organizes inputs and outputs, while the dataset layer handles panel preparation and preprocessing.
• Models turn factor tables into daily stock scores, and strategy rules translate those scores into holdings.
• The article presents several example models and notebooks as starting points, without comparing their performance.
