Stock market forecasting presents numerous challenges due to volatility, complexity, and nonlinear behaviour of financial markets. Recently, many deep learning models have been employed in stock market forecasting, outperforming traditional machine learning techniques. This work examines four artificial neural network models, namely, simple RNN, GRU, LSTM and Bi-LSTM for carrying out comparative study in stock market forecasting. We trained the networks using historical stock data from Standard and Poor’s 500 index and evaluated them based on performance metrics. Based on the experimental results, the LSTM model outperforms all competing configurations.

摘要

Stock market forecasting presents numerous challenges due to volatility, complexity, and nonlinear behaviour of financial markets. Recently, many deep learning models have been employed in stock market forecasting, outperforming traditional machine learning techniques. This work examines four artificial neural network models, namely, simple RNN, GRU, LSTM and Bi-LSTM for carrying out comparative study in stock market forecasting. We trained the networks using historical stock data from Standard and Poor’s 500 index and evaluated them based on performance metrics. Based on the experimental results, the LSTM model outperforms all competing configurations.
