3Frameworks

Framework

Is the model overfit to historical data?

Too many degrees of freedom relative to training period?

847 parameters trained on 5 years = 169 obs/param

Walkforward test degrades 22% vs IS test

Inadvertent look-ahead bias in feature engineering?

Future volume used to compute liquidity score

End-of-day close prices available at 3:59pm UTC

Has market regime shifted since backtest period?

Volatility and correlation changed?

VIX: 12.3 (backtest avg) → 18.7 (live)

Inter-asset correlation +0.34, reduced diversification benefit

Alpha factor under pressure or crowded?

Factor returns -120bps vs +340bps in backtest

23 funds trade same signal, live decay -45%

Implementation and execution issues?

Slippage and market impact underestimated?

Expected slippage 8bps, actual 24bps on live fills

Order size 2.5% of avg volume, moving price against us

Trade timing and execution delays costly?

180ms latency signal generation → order

Alpha half-life 4 minutes, 180ms delay = 13% decay
