Deep Portfolio Theory

By applying deep learning (DL) to classic portfolio optimisation, we show how to capture (or ‘learn’) non-linear features which are invisible to classic portfolio theory. We develop a self-contained four step routine of encode, calibrate, validate, and verify to improve ex-post performance in index tracking and benchmark outperformance.
