In this paper we establish a simple hybrid cognition system which is based on neural netwoks and fuzzy decision theory.For the purpose of analyzing the trends of stock market, we expect that the system can reflect the dynamical character or chsot ic performance of a trading stock market. The whole procedure of the system include: data preprocessing, neural network classif icat ion, fuzzy decision and forecast ing,
