Quant Radio: Seemingly Virtuous Complexity in Return Prediction

Can machine learning really predict stock market returns with just 12 months of data? This episode explores a bold claim made by a prominent academic paper using Random Fourier Features (RFF) to forecast market movements with stunning accuracy — and the fascinating rebuttal that followed.

Join us as we break down:

• The mechanics behind the KMZ RFF strategy

• Why its seemingly impressive performance might just be mathematical coincidence

• How it unintentionally mimics a simple momentum strategy with built-in volatility timing

• What this means for the limits of learning in finance, especially with small data

Through empirical results, intuitive analogies, and critical analysis, we unpack whether complexity in financial models is truly virtuous — or just cleverly disguised simplicity.

💡 Perfect for anyone interested in quant finance, machine learning, or the truth behind flashy claims.
