We present a finite-horizon model of asset pricing with rational speculation and behavioral trading. Unlike the existing literature, our model brings together three key elements characteristic of the bitcoin, dot com, and housing bubbles: (i) time-varying risk based on market sentiment which may evolve into mass hysteria (manias), (ii) inherent difficulties of rational speculation to time the market, and (iii) relatively low volatility of the asset fundamental value. We study various properties of the equilibrium dynamics as well as changes in trading volume. The impact of new information on equilibrium values may be magnified by arbitrageurs’ preemptive motive to move away from the risky asset.
