Overview
As financial markets grow increasingly complex, traditional stock selection models often struggle to capture the intricate interplay between macroeconomic conditions and individual stock performance. In our latest paper, we explore a breakthrough approach— leveraging neural networks within a learning-to-rank framework — to enhance stock selection accuracy.
This paper builds on our prior work with machine learning in portfolio management, incorporating global macroeconomic indicators and advanced optimization techniques to refine predictive power. By dynamically adjusting factor exposures based on real-time economic shifts, our model seeks to improve risk-adjusted returns and deliver a more resilient investment strategy.
How do macro trends influence equity signals? What role do ensemble learning and ranking-based optimisation play in refining stock forecasts? Discover the insights behind our cutting-edge approach.
