Complexity in Factor Pricing Models

Didisheim, Antoine; Ke, Shikun; Kelly, Bryan T.; … - 2023

We theoretically characterize the behavior of machine learning asset pricing models. We prove that expected out-of-sample model performance—in terms of SDF Sharpe ratio and average pricing errors—is improving in model parameterization (or “complexity”). Our results predict that the best...

The Virtue of Complexity Everywhere

Kelly, Bryan T.; Malamud, Semyon; Zhou, Kangying - 2022

We investigate the performance of non-linear return prediction models in the high complexity regime, i.e., when the number of model parameters exceeds the number of observations. We document a "virtue of complexity" in all asset classes that we study (US equities, international equities, bonds,...

Information and inventories in high-frequency trading

Muhle-Karbe, Johannes; Webster, Kevin - 2015

We study how short-term informational advantages can be monetized in a high-frequency setting, when large inventories are explicitly penalized. We find that if most of the additional information is revealed regardless of the high-frequency traders' actions, then fast inventory management allows...

Asset pricing with arbitrage activity

Hugonnier, Julien; Prieto, Rodolfo - 2013

We study an economy populated by three groups of logarithmic agents: Constrained agents subject to a portfolio constraint that limits their risk-taking, unconstrained agents subject to a standard nonnegative wealth constraint, and arbitrageurs with access to uncollateralized credit. Such credit...

Detecting informed trading activities in the options markets

Chesney, Marc; Crameri, Remo; Mancini, Loriano - 2011

We develop statistical methods to detect informed trading in options markets. We apply these methods to 31 companies from various sectors over 14 years analyzing approximately 9.6 million option prices. We find that option informed trading tends to cluster prior to certain events, takes place...

Detecting informed trading activities in the options markets : appendix on subprime financial crisis

Chesney, Marc; Crameri, Remo; Mancini, Loriano - 2011

This appendix extends the empirical results in Chesney, Crameri, and Mancini (2011). Informed trading activities on put and call options are analyzed for 19 companies in the banking and insurance sectors from January 1996 to September 2009. Our empirical findings suggest that certain events such...

Mutual fund competition in the presence of dynamic flows

Breton, Michèle; Hugonnier, Julien; Masmoudi, Tarek - 2008

This paper analyzes competition between mutual funds in a multiple funds version of the model of Hugonnier and Kaniel. We characterize the set of equilibria for this delegated portfolio management game and show that there exists a unique Pareto optimal equilibrium. The main result of this paper...
