This paper tests for the presence of herding on the New York Stock Exchange (NYSE). We measure the degree of herding from 1998-2001, the “bubble” period and its collapse. We estimate the incidence of herding by applying a test of serial independence in the observed interarrival times of...

We show in a simple framework that momentum trading can exist in equilibrium and momentum trading is profitable. Properties of the model fit the empirics well. First, the model captures in a parsimonious manner both short-term overreaction and long-term reversals. Second, it predicts that...

We study the equilibrium in the model proposed by Kyle in 1985 and extended that we consider a framework where the price pressure can be random. We also allow for a random release time of the fundamental value of the asset. This framework includes all the particular Kyle models proposed in the...

This paper sheds new light on the mutual relationship between investor sentiment and excess returns corresponding to the bubble component of stock prices. We propose to use the wavelet concept of the phase angle to determine the lead-lag relation between these variables. The wavelet phase angle...
