Robust reverse engineering of cross-sectional returns and improved portfolio allocation performance using the CAPM
Ni, Xiaohui; Malevergne, Yannick; Sornette, Didier; … - 2011
Following Levy and Roll [2010], we posit that the market portfolio is the efficient tangent Markowitz portfolio, i.e., it is mean-variance efficient. We then reverse engineer the expected returns and variance terms with constraints imposed by empirical data on a hierarchy of asset baskets. This...

Selection in asset markets : the good, the bad, and the unknown
Bottazzi, Giulio; Dindo, Pietro - 2011
We provide simple examples to illustrate how wealth-driven selection works in asset markets. Our examples deliver both good and bad news. The good news is that if individual assets demands are expressed as a fractions of wealth to be invested in each asset, e.g. because traders maximize an...

Measuring financial risk and portfolio optimization with a non-Gaussian multivariate model
Kim, Young Shin; Giacometti, Rosella; Račev, Svetlozar T. - 2012
In this paper, we propose a multivariate market model with returns assumed to follow a multivariate normal tempered stable distribution. This distribution, defined by a mixture of the multivariate normal distribution and the tempered stable subordinator, is consistent with two stylized facts...

Investor protection and the demand for equity
Giannetti, Mariassunta; Koskinen, Yrjö - 2004 - Rev. February 23, 2004
Anecdotal evidence suggests that investor protection affects the demand for equity, but existing theories emphasize only the effect of investor protection on the supply of equity. We build a model showing that the demand for equity is important in explaining financial development. If the level...

Far from the madding crowd : collective wisdom in prediction markets
Bottazzi, Giulio; Giachini, Daniele - 2016
We investigate market selection and bet pricing in a simple Arrow security economy which we show is equivalent to the repeated prediction market models studied in the literature. We derive the condition for long run survival of more than one agent (the crowd) and quantify the information content...

Tracking the Evolution of Idiosyncratic Risk and Cross-Sectional Expected Returns for US REITSs
Cakici, Nusret - 2014
This paper adopts the methodology in Bali and Cakici (2008) in tracking the evolution of the relation between equity REITs' idiosyncratic risk and their cross-sectional expected returns between 1981 and 2010. In addition to the full sample period, we study this relation for (i) all sample REITs,...

Spanning tests for Markowitz stochastic dominance
Arvanitis, Stelios; Scaillet, Olivier; Topaloglou, Nikolas - 2018 - Current draft: January 2018
Using properties of the cdf of a random variable defined as a saddle-type point of a real valued continuous stochastic process, we derive first-order asymptotic properties of tests for stochastic spanning w.r.t. a stochastic dominance relation. First, we define the concept of Markowitz...
