82 Stock Market Trend Prediction Using Levenberg-Marquardt Neural Network Optimized by Genetic Algorithm Available to Purchase

Financial time series forecasting has long been an application area for soft computing techniques. The essential problem is to find a soft computing model that is compatible with technical analysis models used in stock markets. Backpropagation neural networks have often been used to emulate a technical analyst’s prediction. In this paper, two primary technical indicators, William’s %R and Moving Average Convergence Divergence (MACD), have been used for feature extraction from price data. We have focused on optimizing the separabilty of the resulting feature space. Levenberg-Marquardt variation of backpropagation algorithm has been found to be an effective decision engine to predict stock market trends. Due to the complexity of input data feature space, this algorithm converges to sub-optimal minima. Hence, genetic algorithms have been identified as an effective optimization tool to converge closer to global minimum. Accuracy using this method is found to be 50% to 80% for a number of stocks listed on the Bombay Stock Exchange (BSE).
