“…There are many papers that test conditional versions of factor models. For instance, Boguth, Carlson, Fisher, and Simutin (2011), Ferson and Harvey (1999), Farnsworth, Ferson, Jackson, and Todd (2002), Jagannathan and Wang (1996), Kelly, Pruitt, and Su (2019), Lettau and Ludvigson (2001), Lewellen and Nagel (2006), and Moreira and Muir (2017). Our contribution relative to this literature is to show that MHR in asset pricing tests effectively serve as conditioning variables endogenous to the model and that, empirically, multi-horizon factor returns indeed are informative in terms of uncovering novel conditional dynamics of prominent factor models.…”
