We provide statistical estimates of individual security mispricing which is defined as the departure of the market price from the prediction of a fundamental asset pricing model. We show that there is a return premium associated with systematic mispricing risk which is the dependence of the individual security mispricing on a market wide mispricing factor. The risk or characteristic-adjusted re...

T his paper ascertains the extent of mispricing in equity portfolios, mispricing-divestment relation, and the role of African equities as risk diversification strategies during commodity market turbulence. Following Baur and Lucey (2010), one identifies an arbitrary commodity market crisis to be 1%, 5%, and 10% declining moments in returns. However, their approach is extended by usin...

This paper develops a general equilibrium, continuous time model where portfolio constraints generate mispricing between redundant securities. Constrained consumption-portfolio optimization techniques are adapted to incorporate redundant, possibly mispriced, securities. Under logarithmic preferences, we provide explicit conditions for mispricing and closed-form expressions for all economic quan...

Testing market effi ciency in betting markets does not necessarily get around the joint hypothesis problem because the result depends on the assumed role of bookmakers. In a simple model of monopolistic competition, bookmakers’ rational pricing induces the Favorite-Longshot Bias even without bettors’irrationality (Rational Mispricing) and accommodates bettors’irrational beliefs to exploit betti...

This paper studies pricing patterns in a speculative market with asymmetric information populated by both sophisticated and naive traders. Three pricing regimes arise in equilibrium: perfect pricing, with prices equalling asset values, partial mispricing and complete mispricing. Perfect pricing obtains when the presence of naive traders is small although not necessarily zero. When the fraction ...

We study a discontinuous mispricing model of a risky asset under asymmetric information where jumps in the asset price and mispricing are modelled by Lévy processes. By contracting the filtration of the informed investor, we obtain optimal portfolios and maximum expected utilities for the informed and uninformed investors. We also discuss their asymptotic properties, which can be estimated usin...

We investigate optimal portfolio selection problems with mispricing and model ambiguity under a financial market which contains a pair of mispriced stocks. We assume that the dynamics of the pair satisfies a “cointegrated system” advanced by Liu and Timmermann in a 2013 manuscript. The investor hopes to exploit the temporary mispricing by using a portfolio strategy under a utility function fram...

the objective of this study is to examine the effect of mispricing on firm’s investment behavior and capital structure. it also tests the role of the level of financial constraints in the relationship between mispricing , investment and capital structure. using data of 110 firms of tehran stock exchang from 1384-1389, results indicated that mispricing has negative impact to firms investment. ho...

Regulation G requires all companies to quantitatively reconcile pro forma earnings with GAAP earnings. This paper provides three findings related to the impact of reconciliations on mispricing of pro forma earnings. First, prior to Reg G, we find that mis-pricing of pro forma earnings is limited to firms with low reconciliation quality. There is no evidence of mispricing for firms with high rec...
