Mispricing and the five-factor model under different market sentiments

A discontinuous mispricing model under asymmetric information

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...

Market Sentiments Distribution Law

The Stock Exchange is basically ruled by the extreme market sentiments of euphoria and fear. The type of sentiment is given by the color of the candlestick (white = bullish sentiments, black = bearish sentiments), meanwhile the intensity of the sentiment is given by the size of it. In this paper you will see that the intensity of any sentiment is astonishingly distributed in a robust, systemati...

A mispricing model of stocks under asymmetric information

We 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. We obtain analogous but more g...

Rational Mispricing and Irrational Mispricing in Betting Markets: Implications for Market Effi ciency Tests∗

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...
