Abstract:
Abstract. The use of intelligent systems for stock market predictions has been widely established. In this paper, we investigate how the seemingly chaotic behavior of stock markets could be well represented using Flexible Neural Tree (FNT) ensemble technique. We considered the Nasdaq-100 index of Nasdaq Stock Market SM and the S&P CNX NIFTY stock index. We analyzed 7-year Nasdaq-100 main index values and 4year NIFTY index values. This paper investigates the development of novel reliable and efficient techniques to model the seemingly chaotic behavior of stock markets. The structure and parameters of FNT are optimized using Genetic Programming (GP) like tree structure based evolutionary algorithm and Particle Swarm Optimization (PSO) algorithms, repectively. A good ensemble model is formulated by the Local Weighted Polynomial Regression (LWPR). This paper investigates whether the proposed method can provide the required level of performance, which is sufficiently good and robust so as to provide a reliable forecast model for stock market indices. Experimental results show that the model considered could represent the stock indices behavior very accurately. Key Words: Flexible neural tree, GP-like tree structure based evolutionary algorithm, particle swarm optimization, ensemble learning, stock index 1
