This meetup summary covers factor research, equity strategy design, AI models, and live signal timing. For factor processing, it recommends checking both the source data and the calculation logic, including data coverage and accuracy. It suggests studying…
The document raises practical execution questions from a live Chinese stock strategy that submits market buys shortly after the open using a VWAP setting. The trader reports fills above the observed opening price and asks whether VWAP means immediate…
The post lists proposed translations of features from one version of a quantitative research platform to another. Examples include cross-sectional percentile ranks of current and lagged returns, industry-group ranking, candle direction, rolling price and…
This tutorial explains how to construct target labels for supervised learning in equity selection. It distinguishes classification labels, which group observations into discrete outcomes, from continuous regression targets. Label definitions should reflect…
The document describes how the BigAlpha 2026 final evaluates projects across factor discovery, end-to-end large models, and AI open innovation. A team's result combines a leaderboard-based component worth 30 points with a live judging component worth 70. The…
This note offers practical guidance for developing and operating AI-driven equity strategies. It recommends judging possible strategy failure by comparing live maximum drawdown with the largest drawdown observed in a long backtest that spans a full bull and…
This monthly review assesses equity factors using information coefficients and market-neutral long-short returns. Its February 2018 discussion reports stronger results for profitability and growth measures, including return on assets, return on equity,…

The discussion asks how to combine a traditional stock-selection strategy with a machine-learning ranker. The user has a screening method that produces too many candidates and wants to rank those stocks afterward. The post contrasts traditional strategies,…
This overview discusses how machine learning can address high-dimensional and nonlinear return-prediction problems that strain conventional econometric methods. It frames the challenge through empirical asset pricing, including factor models, a proliferation…
The document outlines a two-stage quantitative investing workflow: combine several signals into a single factor score, then optimize portfolio weights against a chosen objective. It names linear combination as one approach to factor synthesis and mentions an…
