This paper re-examines the issue of mean reversion in stock prices by incorporating the structural break effect in the long horizon regression. Before adjusting for structural break, the paper finds that previous studies understate the evidence of mean-reversion. The understatement is mainly due...

This thesis consists of four papers. The first three deal with deterministic chaos in exchange rate series whereas the fourth deals with technical analysis in the foreign exchange market. Paper [i] (

Can nominal exchange rates be characterized by deterministic chaos? To answer this question, a statistical framework utilizing a blockwise bootstrap procedure is used to test for the presence of a positive Lyapunov exponent in an observed stochastic time series (Bask and Gencay, 1998). Daily...
