Panel Coupled Matrix-Tensor Clustering for Asset Pricing

This paper addresses the limitations of traditional asset pricing models by introducing a novel Panel Coupled Matrix-Tensor Clustering (PMTC) model. It leverages both a characteristics tensor and a return matrix to improve clustering accuracy and factor loading estimation, particularly in noisy and sparse data scenarios. The integration of multiple data sources and the development of computationally efficient algorithms are key contributions. The empirical application to U.S. equities suggests practical value, showing improved out-of-sample performance.
