Empirical Asset Pricing via Learning-to-Rank
A new study introduces the learning-to-rank method, widely used in information retrieval, to empirical asset pricing in finance. The authors show that ranking stocks by predicted returns is more effective than traditional regression models. Their tests on financial data reveal that learning-to-rank models better identify top-performing stocks. The paper also suggests new ways to evaluate asset pricing models, though it notes the need for more detailed results and discussion of model interpretability and market adaptability.
What it examines
This paper explores how learning-to-rank, a machine learning approach, can be used in finance for predicting asset returns. It reviews existing algorithms and literature, aiming to show how ranking methods can improve empirical asset pricing, which has been mostly overlooked in financial research.
What it concludes
The study finds that learning-to-rank methods can enhance return prediction and asset pricing. These techniques may help investors and financial analysts make better decisions. Limitations include the need for more data and testing. Future research could refine these models and expand their use in real-world finance applications.
Evidence objects
Researchers introduce learning-to-rank, a machine learning technique from information retrieval, to asset pricing, arguing it offers more practical and informative stock ranking than traditional regression-based predictions in finance.
