Factor model performance rankings and pricing errors vary materially with test portfolio construction methods, making construction a key design choice in model evaluation.
Benchmark of 15 time-series architectures on equity portfolios finds no model dominates, with TransEnc-8 at 0.352 rank-1 acceptability and all promoted models showing negative net Sharpe at 20 bps costs under constraints.
