Small Trade, Retail Investors and Asset Dynamics
نویسنده
چکیده
In this paper, we construct a model incorporating the retail trader’s reluctance to sell into losses. We show that in this setup the informed trader always buys the asset when he receives a favorable signal. However, when the informed trader receives an unfavorable signal, he may not sell the asset if the signal is moderately bad and the retail trader is reluctant to realize losses. Hence the asset price exhibits steady climbs with sharp and sudden drops. We then test the empirical implications using a set of high-tech stocks, many of which are dominated by retail investors. We show that the prices of these companies exhibit pattern of steady rises with sudden drops. The more trading activities by the retail investors, the more pronounced this pattern. ∗Fuqua School of Business, Duke University, Durham, NC 27708. email: [email protected].

متن کاملDynamic Trading and Asset Prices: Keynes vs. Hayek
We investigate the dynamics of prices, information and expectations in a competitive, noisy, dynamic asset pricing equilibrium model with long-term investors. We argue that the fact that prices can score worse or better than consensus opinion in predicting the fundamentals is a product of endogenous short-term speculation. For a given, positive level of residual payoff uncertainty, if noise tra...
