alpha-combination-and-neutralization
Score several alphas, combine them, and strip the exposures you did not mean to take. TRIGGER - information coefficient, IC, rank IC, ICIR, IC decay, "is my IC good", IC t-stat, Newey-West on IC, overlapping forward returns; combining alphas, blending signals, alpha weighting, z-score or rank combination, multi-factor signal; sector neutral, beta neutral, market neutral signal, industry neutralization, residualize the alpha, cross-sectional regression residuals, orthogonalize signals; winsorize, clip outliers, cross-sectional standardization; turnover-aware combination, signal smoothing, "my alpha dies after costs". SKIP for one time-series trend signal (trend-following-models), for the factor library and the alphalens forward-return convention (factor-and-timeseries-research, lib-alphalens), for weights under constraints (portfolio-and-risk), and for whether the survivor is real (backtest-validation).
factor-and-timeseries-research
Judge whether a cross-sectional factor predicts returns, and forecast financial series. TRIGGER - information coefficient, IC, quantile returns, factor decay, turnover, alphalens; Fama-French, Fama-MacBeth, PanelOLS, linearmodels, cross-sectional asset pricing; event study, abnormal returns, CAR, BHAR; Alpha101, Alpha158, symbolic alpha mining, gplearn; or forecasting with ARIMA, GARCH, volatility models, arch, Nixtla, statsforecast, mlforecast, sktime, darts, Prophet or a time-series foundation model. SKIP for computing the indicator itself (signal-construction) and for portfolio weights or Sharpe (portfolio-and-risk).
factor-research
Evaluate whether a cross-sectional factor genuinely predicts returns. Trigger for "这个因子有效吗", "算一下IC", "动量因子在A股还有效吗", "帮我评估这个选股信号", "factor IC", "is this signal predictive", "compare momentum vs value factors", or whenever the user (1) proposes or computes a ranking/score across assets and asks if it works, (2) asks which factor explains recent moves, (3) wants factors screened/ranked before building a strategy, or (4) hands a signal to strategy construction. Fire even for informal phrasing ("这个指标选股靠谱吗"). Do NOT trigger for single-asset technical indicator questions (no cross-section) or for validating a finished strategy's returns (that is backtest-validation).
