A great proportion of stock dynamics can be explained using publicly available information. The relationship between dynamics and public information may be of nonlinear character. In this paper we offer an approach to stock picking by employing so-called decision trees and applying them to XETRA...

Portfolio Dynamics and Expected Returns Under Illiquidity

Buchner, Axel - 2015

Using a novel continuous-time framework, this paper explores the effects of illiquidity on portfolio dynamics and expected returns. In summary, the paper makes three key contributions to the existing literature on asset pricing and illiquidity. First, it illustrates that illiquidity leads to...

Dispersion in Options Investors’ Versus Analysts’ Expectations : Predictive Inference for Stock Returns

Andreou, Panayiotis C. - 2019

We create a market-wide measure of dispersion in options investors' expectations by aggregating across all stocks the dispersion in trading volume across moneynesses (DISP). DISP exhibits strong negative predictive power for future market returns and its information content is not subsumed by...

Expected Equity Returns Should Correlate with Idiosyncratic Risk

Bruno, Giovanni - 2018

law of one price, and is present in all but risk-neutral economies. We test the cross-sectional predictions of our theory … equity than for assets, and stronger for more levered firms — consistent with the theory. We test also the timeseries … implications of the theory. Time variation in asset ivol causes time variation in the option value of equity that translates into …

Institutional Investors, Heterogeneous Benchmarks and the Comovement of Asset Prices

Buffa, Andrea M - 2018

We study the equilibrium implications of a multi-asset economy in which asset managers are subject to different benchmarks, and demonstrate how heterogeneous benchmarking generates a mechanism through which fundamental shocks propagate across assets. Fluctuations in asset managers' capital...

Asymmetric Information, Trading Volume, and Portfolio Performance

Jackson, Antony - 2013

In dealership markets, asymmetric information feeds through to higher transaction costs as dealers adjust their bid-ask spreads to compensate for anticipated losses. In this paper, we show that the presence of asymmetric information can also provide a positive externality to those market...

Price impact and portfolio impact

Cvitanić, Jakša; Malamud, Semyon - 2010

We study survival, price impact and portfolio impact in heterogeneous economies. We show that, under the equilibrium risk-neutral measure, long-run price impact is in fact equivalent to survival, whereas longrun portfolio impact is equivalent to survival under an agent-specific, wealth-forward...

Multivariate tests of mean-variance efficiency and spanning with a large number of assets and time-varying covariances

Gungor, Sermin; Luger, Richard - 2013

We develop a finite-sample procedure to test for mean-variance efficiency and spanning without imposing any parametric assumptions on the distribution of model disturbances. In so doing, we provide an exact distribution-free method to test uniform linear restrictions in multivariate linear...
