Quant Links: Does Longer Historical Training Improve HMM Market-Regime Out-of-Sample Performance?
ORIGINAL / Recent Quant Links from Quantocracy as of 10/14/2026
Quantocracy's recent quant links as of October 14, 2026 highlight a study asking whether longer historical training periods improve the out-of-sample performance of an HMM market-regime model, with attention to the difficulty of out-of-sample evaluation. This is useful for quantitative researchers because it frames training-window length, market-regime modeling, and out-of-sample evaluation together.
01 ABSTRACT
