A Mispricing Model Of Stocks Under Asymmetric Information

The authors extend the theory of asymmetric information in mispricing models for stocks following geometric Brownian motion to constant relative risk averse investors. Mispricing follows a continuous mean - reverting Ornstein - Uhlenbeck process. Optimal portfolios and maximum expected log - linear utilities from terminal wealth for informed and uninformed investors are derived. They obtain analogous but more general results which nests those of Guasoni (2006) as a special case of the relative risk aversion approaching one.
