Non-Linearity and Chaotic Behaviour in Cyprus Stock Market

The intention of this research is to investigate the aspect of non-linearity and chaotic behaviour of the Cyprus stock market. For this purpose, we use non-linearity and chaos theory. We perform BDS, Hinich-Bispectral tests and compute Lyapunov exponent of the Cyprus General index. The results show that existence of non-linear dependence and chaotic features as the maximum Lyapunov exponent was found to be positive. This study is important because chaos and efficient market hypothesis are mutually exclusive aspects. The efficientmarket hypothesis which requires returns to be independent and identically distributed (i.i.d.) cannot be accepted.
